Approval, on an Advisory Basis, of the Compensation of our Named Executive Officers
We are asking our shareholders to approve, on a non-binding, advisory basis, the compensation of our named executive officers. The Board believes that our executive compensation policies are designed appropriately and are functioning as intended to produce long-term value for our shareholders.
Fiscal 2017 Executive Compensation Elements
Type		Form			General Purpose and Terms
Cash		Base Salary			Retention component that is reviewed annually and adjusted as needed, and executives are generally eligible for an annual increase.
		Non-Equity Performance Incentive Plan ("PIP")			Motivates and rewards performance by linking a significant portion of compensation to profitability. Earned monthly based upon a fixed percentage, or participation factor, of our pre-tax income. No payment unless pre-tax income exceeds a required minimum performance threshold.
Equity-based		Restricted Stock			Aligns executive compensation with Company performance and shareholder value. Any shares earned generally vest in increments of 33% per year on the anniversary of the grant date, subject to continued service requirements.
Other Employee Benefits		401(k) Plan			Retirement plan with Company match; executive officers receive the same benefit as all employees.
		Nonqualified Deferred Compensation Plan			Supplemental retirement benefit; can defer significant percentages of annual base salary and monthly non-equity performance-based incentive compensation.

Fiscal 2017 Compensation Decisions
The principal factors in the Compensation Committee’s executive compensation decisions for 2017 were our financial performance, the relationship of executive compensation to our pre-tax income, the amount of compensation that is performance-based, and the review and analysis conducted by its independent compensation consultant, Pearl Meyer. Based on our industry-leading financial results for 2017 and our outlook for 2018, the Compensation Committee approved a 3.0% increase in the base salaries for our named executive officers effective in January 2018. In keeping with our philosophy of pay-for-performance, PIP payments to our named executive officers increased in 2017 as compared to 2016, as these payments were directly aligned with our financial performance.
Fiscal 2017 Compensation Summary
The following table summarizes the compensation of our Chief Executive Officer, our Chief Financial Officer, and our next three most highly compensated executive officers, to whom we refer to collectively as our named executive officers, for the fiscal year ended December 31, 2017.

GENERAL INFORMATION

The accompanying proxy is solicited by and on behalf of our Board of Directors (the "Board"), and the entire cost of such solicitation will be borne by us. This solicitation is being made by mail and may also be made in person or by fax, telephone, or Internet by our officers or employees. In addition, arrangements will be made with brokerage houses and other custodians, nominees and fiduciaries to send proxy materials to their principals, and we will reimburse them for their reasonable expenses in connection therewith.

The accompanying proxy is for use at the 2018 Annual Meeting of Shareholders (the “Annual Meeting”) if a shareholder either will be unable to attend in person or will attend but wishes to vote by proxy. “Registered holders” who have shares registered in the owner's name through our transfer agent may vote by either: (i) completing the enclosed proxy card and mailing it in the postage-paid envelope provided; (ii) voting over the Internet by accessing the website identified on the proxy card and following the on-line instructions; or (iii) calling the toll-free telephone number identified on the proxy card. Proxies submitted via the Internet or by telephone must be received by 11:59 p.m. Eastern Daylight Time on Tuesday, May 15, 2018.

For shares held in “street name,” that is, shares held in the name of a brokerage firm, bank or other nominee, you should receive a voting instruction form from that institution in lieu of a proxy card. The voting instruction form should indicate whether the institution has a process for beneficial holders to vote over the Internet or by telephone. Many banks and brokerage firms participate in the online program offered by Broadridge Financial Solutions, Inc. This program provides eligible shareholders who receive a paper copy of the proxy statement the opportunity to vote over the Internet or by telephone. The Broadridge Internet and telephone voting facilities will close at 11:59 p.m. Eastern Daylight Time on Tuesday, May 15, 2018. The Broadridge Internet and telephone voting procedures are designed to authenticate the shareholder's identity and to allow shareholders to vote their shares and confirm that their instructions have been properly recorded. If the voting instruction form does not reference Internet or telephone information, or if the shareholder prefers to vote by mail, please complete and return the paper voting instruction form in accordance with the instructions provided to you.

If you decide to attend the meeting in person, upon your arrival you will need to register with our receptionist in the main lobby of our principal executive offices at 500 Old Dominion Way, Thomasville, North Carolina 27360. Please be sure to have your state or government issued photo identification with you at the time of registration. After a determination that you are a registered holder of Old Dominion common stock as of the record date, you will be allowed to access the meeting room and attend our Annual Meeting. If you are not a registered shareholder but beneficially own shares of our common stock as of the record date, please be sure that you bring your state or government issued photo identification as well as either (i) a proxy issued to you in your name by your brokerage firm, bank or other nominee, or (ii) a brokerage statement showing your beneficial ownership of our common stock as of the record date (and a legal proxy from your brokerage firm, bank or other nominee if you wish to vote your shares at the Annual Meeting) to present to us at the time of registration.

The Board of Directors has fixed March 8, 2018 as the record date for the determination of shareholders entitled to notice of and to vote at the Annual Meeting. On March 8, 2018, there were 82,336,522 outstanding shares of our common stock, each entitled to one vote. The presence in person or by proxy of a majority of the shares of common stock outstanding on the record date constitutes a quorum for purposes of conducting business at the Annual Meeting. Shareholders do not have cumulative voting rights in the election of directors.

Brokers that are members of certain securities exchanges and that hold shares of our common stock in street name on behalf of beneficial owners have authority to vote on certain items when they have not received instructions from beneficial owners. Under the applicable rules governing such brokers, the proposal to ratify the appointment of our independent registered public accounting firm is considered a “discretionary” item. This means that brokers may vote using their discretion on this proposal on behalf of beneficial owners who have not furnished voting instructions. In contrast, certain items are considered “non-discretionary,” and a “broker non-vote” occurs when brokers do not receive voting instructions from beneficial owners with respect to such items because the brokers are not entitled to vote such uninstructed shares. All proposals in this proxy statement, with the exception of the proposal to ratify the appointment of our independent registered public accounting firm, are considered “non-discretionary,” which means that brokers cannot vote your uninstructed shares when they do not receive voting instructions from you.

-5-

Assuming the existence of a quorum at the Annual Meeting, the voting options for each proposal presented in this proxy statement, as well as the vote required to approve each proposal at the Annual Meeting, are as follows:

Proposal 1 - Election of Directors: With respect to this proposal, you may cast your vote “for all,” “withhold all” or “for all except” with respect to the director nominees. The nominees receiving a plurality of the votes cast will be elected as directors.

Proposal 2 - Approval, on an Advisory Basis, of the Compensation of Our Named Executive Officers: With respect to this proposal (the results of which will not be binding upon Old Dominion or the Board), you may vote “for,” “against,” or “abstain” from voting. For this non-binding vote to be approved by the shareholders, the votes cast “for” this proposal must exceed the votes cast “against” this proposal.

Proposal 3 - Ratification of the Appointment of Our Independent Registered Public Accounting Firm: With respect to this proposal, you may vote “for,” “against,” or “abstain” from voting. For this proposal to be approved by the shareholders, the votes cast “for” this proposal must exceed the votes cast “against” this proposal.

Abstentions, shares that are withheld as to voting and broker non-votes (if any) will be counted for determining the existence of a quorum, but will not be counted as a vote cast with respect to any of these proposals and, therefore, will have no effect on the outcome of the vote for any of these proposals.

Where a choice is specified on any proxy as to the vote on any matter to come before the Annual Meeting, the proxy will be voted in accordance with such specification. If no specification is made but the proxy is otherwise properly completed, the shares represented thereby will be voted “for” the election of the director nominees named in this proxy statement, “for” the approval, on an advisory basis, of the compensation of our named executive officers, and “for” the ratification of the appointment of our independent registered public accounting firm. Any shareholder submitting the accompanying proxy has the right to revoke it by notifying our Corporate Secretary in writing at any time prior to the voting of the proxy. A proxy is suspended if the person giving the proxy attends the Annual Meeting and properly elects to vote in person.

Management is not aware of any matters, other than those specified above, that will be presented for action at the Annual Meeting. If any other matters do properly come before the Annual Meeting, the persons named as agents in the proxy will vote upon such matters in accordance with their best judgment.

PROPOSAL 1 - ELECTION OF DIRECTORS

Our Bylaws currently provide that the number of directors shall be not less than five nor more than twelve. Upon the recommendation of its Governance and Nomination Committee, the Board has determined to increase its size from nine directors to eleven directors. The Board, upon the recommendation of its Governance and Nomination Committee, has nominated nine current directors and two new nominees - Sherry A. Aaholm and Greg C. Gantt - for election to the Board at the Annual Meeting. The Governance and Nomination Committee discussed multiple candidates as potential director nominees following an extensive selection process, including due consideration of diversity and other criteria as set forth in our Corporate Governance Guidelines relating to the recommendation of director nominees, and also obtained input from our CEO and other members of management

-9-

as appropriate. In recruiting Ms. Aaholm, the Board paid a fee to a third-party search firm to help identify director prospects, perform candidate outreach, and provide other related services. Following completion of this process and multiple meetings with members of the Board and Old Dominion’s management team, Ms. Aaholm was formally nominated for election to the Board at the Annual Meeting. Mr. Gantt, who will assume the role of the Company’s President and Chief Executive Officer on May 16, 2018, was formally nominated to the Board based on his experience in serving as our President and Chief Operating Officer and our long-standing practice of having our Chief Executive Officer serve as a member of the Board. If elected, the eleven nominees identified herein will serve until our 2019 annual meeting of shareholders and until their respective successors have been elected and qualified or until their death, resignation, removal or disqualification or until there is a decrease in the number of directors. Unless authority is withheld, it is intended that proxies received in response to this solicitation will be voted in favor of the nominees.

The age and a brief biographical description of each director nominee, his or her position with us, certain board memberships, and the nominee’s specific experience, qualifications, attributes and skills that led our Board to conclude that the candidate is well-qualified to serve as a member of our Board are set forth below. This information and certain information regarding beneficial ownership of securities by such nominees contained in this proxy statement has been furnished to us by the nominees or obtained from filings with the SEC. All of the nominees have consented to serve as directors, if elected.

CORPORATE GOVERNANCE

Board Leadership Structure

Historically, our Chairman of the Board has also served as our Chief Executive Officer, and these dual roles were held for many years by our current Executive Chairman of the Board, Earl E. Congdon. In 2007, however, following Earl E. Congdon's decision to resign from the Chief Executive Officer position effective on January 1, 2008, the Board determined that it was in the best interests of our shareholders to appoint David S. Congdon, who had been serving as our President and Chief Operating Officer, as our Chief Executive Officer and to redesignate Earl E. Congdon as Executive Chairman of the Board. The Board took these actions because it wanted to preserve the ability of Earl E. Congdon to continue to have a significant executive role on our management team. The Board also believes that strong, independent Board leadership is an important aspect of effective corporate governance and, as a result, appointed Robert G. Culp, III in January 2010 to serve as our Lead Independent Director. Our Lead Independent Director's responsibilities and authority include presiding at meetings of our independent directors, coordinating with our Executive Chairman and Chief Executive Officer on Board meeting agendas, schedules and materials and otherwise acting as a liaison between the independent directors, our Executive Chairman and our Chief Executive Officer. For these reasons, the Board believes that this leadership structure, as further enhanced by the changes described below effective May 16, 2018, is appropriate for us. The Board believes that there is no specific generally accepted leadership structure that applies to all companies, nor is there one specific leadership structure that permanently suits us. As a result, our decision as to whether to combine, separate or add to the positions of Chairman and Chief Executive Officer and whether to have a Lead Independent Director may vary from time to time, as industry or our own conditions and circumstances warrant. The independent directors of the Board consider the Board's leadership structure on an annual basis to determine the structure that is most appropriate for the governance of Old Dominion.

On March 8, 2018, the Board, as part of its designed succession plan, approved strategic leadership changes effective May 16, 2018. Specifically, Greg C. Gantt will serve as our President and Chief Executive Officer, David S. Congdon will serve as our Executive Chairman and Earl E. Congdon will serve as our Senior Executive Chairman. These changes will continue to maintain the general characteristics of the leadership structure described above, while preserving the ability of Earl E. Congdon and David S. Congdon to have significant roles on our management team.

Independent Directors

In accordance with the listing standards of The Nasdaq Stock Market, LLC (“Nasdaq”), our Board of Directors must consist of a majority of independent directors. The Board, upon the recommendation of the Governance and Nomination Committee, has determined that current directors Messrs. Culp, Gabosch, Hanley, Kasarda, Suggs and Wray and director nominee Ms. Aaholm are each independent in accordance with Nasdaq listing standards. The Board performed a review to determine the independence of its members and Ms. Aaholm and made a subjective determination as to each that no transactions, relationships or arrangements exist that, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director of Old Dominion. In making these determinations, the Board considered information provided by the current directors as well as Ms. Aaholm and Mr. Gantt, in addition to information obtained by us, with regard to each individual's business and personal activities as they may relate to us and our management. Our Corporate Governance Guidelines direct the independent directors of the Board to meet in executive session at least twice each year, and they met five times in 2017. Shareholders may communicate with the independent directors by following the procedures set forth in “Shareholder Communications with the Board” in this proxy statement.

-13-

Attendance and Committees of the Board

Pursuant to our Corporate Governance Guidelines, directors are expected to attend the Annual Meeting and all meetings of the Board, including all meetings of Board committees of which they are members. All directors then in office were present at the 2017 Annual Meeting that was held on May 17, 2017. Our Board of Directors held five meetings during 2017. The Board of Directors has three standing committees: the Audit Committee, the Compensation Committee and the Governance and Nomination Committee. Each member of the Audit Committee, the Compensation Committee and the Governance and Nomination Committee is an “independent director” as such term is defined under applicable SEC rules and regulations and Nasdaq listing standards. In 2017, all incumbent directors attended at least 75% of the aggregate meetings held by the Board and their assigned committees during the period for which they served on the Board or such committees.

Audit Committee

The Audit Committee, which is a separately-designated standing Audit Committee established in accordance with section 3(a)(58)(A) of the Exchange Act, currently consists of D. Michael Wray (Chair), Robert G. Culp, III, Bradley R. Gabosch, and Patrick D. Hanley, each of whom the Board of Directors has determined is independent pursuant to applicable SEC rules and regulations and Nasdaq listing standards. The Board of Directors has determined that all Audit Committee members are financially literate and that Messrs. Gabosch, Hanley and Wray each qualify as an “audit committee financial expert” as defined by applicable SEC rules. Please refer to the experience described for each of these members under “Proposal 1 - Election of Directors” in this proxy statement.

The Audit Committee is governed by a written charter approved by the Board of Directors, which is available on our website at http://www.odfl.com/Content/corpGovernance.faces. The Committee annually reviews this charter to reassess its adequacy and recommends any proposed changes to the Board of Directors for approval. Committee members are nominated annually by the Governance and Nomination Committee and approved by our Board of Directors to serve for one-year terms. Information regarding the functions performed by this committee is set forth in the “Report of Audit Committee,” which is included in this proxy statement. The Audit Committee met four times and held seven telephonic meetings in 2017. The Audit Committee holds telephonic meetings after each quarterly period to discuss with both management and our independent registered public accounting firm, Ernst & Young LLP (“EY”), the financial results to be included in our periodic filings with the SEC prior to their release.

Compensation Committee

Our Compensation Committee currently consists of Robert G. Culp, III (Chair), Patrick D. Hanley, Leo H. Suggs and D. Michael Wray, each of whom the Board of Directors has determined to be independent pursuant to applicable SEC rules and regulations and Nasdaq listing standards. Committee members are nominated annually by the Governance and Nomination Committee and approved by our Board of Directors to serve for one-year terms.

The Compensation Committee is responsible for reviewing the components of our compensation plans for our officers, including an evaluation of the components of compensation, the standards of performance measurements and the relationship between performance and compensation. The Compensation Committee is also responsible for reviewing the results of our most recent “say-on-pay” vote and any shareholder feedback from our shareholder outreach initiatives, and considering whether any adjustments to our compensation policies and practices are necessary or appropriate in light of such “say-on-pay” vote or shareholder feedback. Please refer to our compensation philosophy described in the “Compensation Discussion and Analysis” section of this proxy statement for further discussion, including the role of executive officers in determining or recommending the amount or form of executive and director compensation. The Compensation Committee also reviews and evaluates our non-employee director compensation program, and recommends changes as deemed necessary to maintain alignment with our compensation philosophy.

The Compensation Committee is governed by a written charter approved by the Board of Directors, which is available on our website at http://www.odfl.com/Content/corpGovernance.faces. The Committee annually reviews this charter to reassess its adequacy and recommends any proposed changes to the Board of Directors for approval. The Committee meets periodically and is authorized to obtain opinions or reports from external or internal sources as it may deem appropriate or necessary to assist and advise it in connection with its responsibilities. The Compensation Committee met four times in 2017. In addition, the Chair of the Compensation Committee meets periodically with our Chief Executive Officer and our President to review and evaluate our executive compensation

-14-

program and the relationship between performance and compensation. In accordance with its charter, the Committee may delegate authority to one or more members of the Committee as deemed necessary to fulfill its responsibilities. No such authority was delegated in 2017.

To assist the Compensation Committee with its review and analysis of executive, non-employee director and employee compensation matters, the Compensation Committee has engaged the services of an independent compensation consulting firm, Pearl Meyer, periodically since 2013. In July 2015, Pearl Meyer was instructed to conduct a review and analysis of our executive compensation program as well as our non-employee director compensation program. In June 2016, Pearl Meyer was instructed to conduct a review and analysis of our executive compensation program. In July 2017, the Compensation Committee once again engaged Pearl Meyer to review the competitiveness of and provide recommendations for our executive compensation program, to analyze our business performance and executive compensation relative to our peer group, to provide input on our short- and long-term incentive programs, and to conduct a review and analysis of our non-employee director compensation program. For a more detailed discussion of the nature and scope of the role of Pearl Meyer with respect to our compensation programs, please see “Compensation Discussion and Analysis - Role of the Compensation Consultant” and “Director Compensation - Components of Compensation” below.

Governance and Nomination Committee

The Governance and Nomination Committee currently consists of John D. Kasarda (Chair), Bradley R. Gabosch and Leo H. Suggs, each of whom the Board of Directors has determined is independent pursuant to applicable Nasdaq listing standards. This Committee makes recommendations concerning the size and composition of the Board of Directors, evaluates and recommends candidates for election as directors (including nominees recommended by shareholders), coordinates the orientation (in conjunction with our Chief Executive Officer) and educational requirements of new and existing directors, develops and implements our corporate governance policies and assesses the effectiveness of the Board of Directors and its committees. We also maintain a corporate membership in the National Association of Corporate Directors (“NACD”), which provides our Board members with opportunities and resources to continue to enhance their knowledge of current governance best practices and emerging issues faced by public company directors.

The Governance and Nomination Committee is governed by a written charter approved by the Board of Directors, which is available on our website at http://www.odfl.com/Content/corpGovernance.faces. The Committee annually reviews this charter to reassess its adequacy and recommends any proposed changes to the Board of Directors for approval. Committee members are appointed annually by a majority of the Board of Directors to serve for one-year terms. The Governance and Nomination Committee met four times in 2017.

Corporate Governance Guidelines

The Board has adopted written Corporate Governance Guidelines, which provide the framework for fulfillment of the Board's duties and responsibilities in light of various best practices in corporate governance and applicable laws and regulations. The Corporate Governance Guidelines address a number of matters applicable to directors, including director qualification standards, our withhold vote policy, meeting requirements and responsibilities of the Board and its committees. The Corporate Governance Guidelines are available on our website at http://www.odfl.com/Content/corpGovernance.faces.

Code of Business Conduct

Shareholder Communications with the Board

Any shareholder desiring to contact the Board or any individual director serving on the Board may do so by written communication mailed to: Board of Directors (Attention: (name of director(s), as applicable)), care of the Corporate Secretary, Old Dominion Freight Line, Inc., 500 Old Dominion Way, Thomasville, North Carolina 27360. Any communication so received will be processed by our Corporate Secretary and be promptly delivered to the appropriate member(s) of the Board.

Director Nominations

The Governance and Nomination Committee will consider qualified director nominees recommended by shareholders when such recommendations are submitted in accordance with our bylaws and policies regarding director nominations. Shareholders may submit in writing the names and qualifications of potential director nominees to our Corporate Secretary (500 Old Dominion Way, Thomasville, North Carolina 27360) for delivery to the Chair of the Governance and Nomination Committee for consideration. When submitting a nomination to the Governance and Nomination Committee for consideration, a shareholder must provide the following minimum information for each director nominee: (i) full name, age, business address and, if known, residence address; (ii) principal occupation or employment; (iii) number of our shares of common stock beneficially owned; (iv) all information relating to such person that would be required to be disclosed in a proxy statement for the election of directors (including such person's written consent to being named in the proxy statement as a nominee and serving as a director if elected); and (v) a description of all direct and indirect compensation or other material monetary agreements during the past three years, and any other material relationships between or among the nominating shareholder (and his respective affiliates and associates) and the director nominee (and his respective affiliates and associates). The shareholder's nomination must also include, among other things, information regarding that shareholder's economic, voting and other interests that may be material to our and our shareholders' evaluation of the director nominee.

Shareholder nominations for director must also be made in a timely manner and otherwise in accordance with our bylaws, as described in more detail in Article 3, Section 6 of our bylaws. If the Governance and Nomination Committee receives a director nomination from a shareholder or group of shareholders who (individually or in the aggregate) have beneficially owned greater than 5% of our outstanding stock for at least one year prior to the date of nomination, we, to the extent required by applicable securities law, will identify the candidate and shareholder or group of shareholders recommending the candidate and will disclose in our proxy statement whether the Governance and Nomination Committee chose to nominate the candidate, as well as certain other information required by SEC rules and regulations.

In addition to any director nominees submitted by shareholders, the Governance and Nomination Committee considers any candidates submitted by directors, as well as self-nominations by directors, and it also may consider candidates submitted by a third-party search firm hired for the purpose of identifying director candidates. Also, from time to time the Governance and Nomination Committee may also consider candidates identified through outside networks or other sources focused on diversity in gender, race, ethnicity, culture/viewpoint, geography, or other qualities or attributes that the Governance and Nomination Committee believes are important in evaluating qualified director candidates. The Governance and Nomination Committee investigates potential director candidates and their individual qualifications, and all such candidates, including those submitted by shareholders, are similarly evaluated by the Governance and Nomination Committee.

In evaluating prospective nominees, the Governance and Nomination Committee considers the criteria outlined in our Corporate Governance Guidelines, which include personal and professional ethics, integrity and values; director independence; relevant educational and business experience; willingness to devote the time required to fulfill the duties of a director and to develop additional insight into our operations; and a willingness to represent the best interests of us and our shareholders and be objective in evaluating management's effectiveness. The Governance and Nomination Committee also considers various skills, attributes and qualities of prospective nominees, as well as current Board members, that are particularly relevant to our business and a strong and effective Board, which include the following:

• Industry - Extensive knowledge and experience in the freight transportation and logistics industry;

-16-

• Executive Management - Senior level experience in operations, strategic planning, risk management and oversight, finance and economics, and treasury and securities markets;

• Diversity - Diverse talents, perspectives and backgrounds (including with respect to gender, race, ethnicity and national origin);

• Human Resources and Safety - Knowledge of employee relations, safety and environmental issues;

• Shareholder Relations - Understanding of public company governance and institutional investor considerations;

• Customer Relations - Insight into marketing, sales and customer relationship management;

• Information Technology - Understanding of information technology, cybersecurity, information systems and related issues;

• International/Global - Knowledge of global trends and considerations relating to supply chain management and multimodal transportation solutions; and

• Legal/Regulatory/Government Affairs - Understanding of legal and regulatory implications, including a strong grasp of the workings of government and public policy on a local, state and national level.

In addition to these specific categories, the Governance and Nomination Committee considers a number of other factors in considering director candidates, including board dynamics, reputation of potential nominees, and expected contributions of the nominee to the Board and its committees.

In seeking and evaluating prospective director nominees, diversity in gender, race, ethnicity, culture, tenure of Board service, viewpoint, geography, and other qualities and attributes are important factors to consider in connection with the criteria outlined above and equal opportunity principles. Although we do not have a formal policy for the consideration of diversity in identifying director nominees, we and the Governance and Nomination Committee are committed to the consideration of diversity in connection with the criteria outlined above and as set forth in our Corporate Governance Guidelines when recommending director nominees so that the Board, as a whole, will possess the appropriate background, skills, experience and expertise to oversee our business. Although we and the Governance and Nomination Committee believe that the current composition of the Board of Directors, together with Ms. Aaholm and Mr. Gantt, reflects a highly talented group of individuals best suited to perform oversight responsibilities for us and our shareholders at this time, we will continue to consider diversity factors as we evaluate the current and future composition of our Board. The Governance and Nomination Committee regularly monitors the effectiveness of its prospective director evaluation process, including its consideration of diversity, through our internal self-evaluation process in which directors discuss and evaluate the composition and functioning of the Board and its committees.

After the prospective director evaluation process is concluded, the Governance and Nomination Committee selects and submits nominees to the Board for further consideration and approval.

Effect of Withheld Votes on an Uncontested Election

In an uncontested election of directors, any director nominee who receives a greater number of votes "withheld" from his or her election than votes "for" such election shall immediately offer his or her resignation for consideration by the Governance and Nomination Committee. This resignation is conditioned upon the Board's acceptance and thus shall not be effective unless and until the Board of Directors, after considering the recommendation of the Governance and Nomination Committee, accepts the director nominee's offer to resign. Nevertheless, if the director nominee does not wish to remain a director, he or she shall so state and shall tender a non-conditional resignation, which shall be effective as of the date thereof.

The Governance and Nomination Committee will promptly consider the director nominee's offer to resign and will recommend to the Board of Directors whether to accept or reject it. In making this recommendation, the Governance and Nomination Committee will consider all factors deemed relevant by its members, including, without limitation, the stated reasons, if any, why shareholders "withheld" votes for election from such director nominee, the

-17-

length of service and qualifications of the director nominee, the director nominee's contributions to us, our Corporate Governance Guidelines, whether accepting the offered resignation would cause us to fail to meet any applicable SEC or Nasdaq requirements and whether the director's resignation from the Board of Directors would be in the best interests of us and our shareholders.

The Board of Directors will act on the Governance and Nomination Committee's recommendation no later than 90 days following the date of the shareholders' meeting at which the election occurred. In considering the Governance and Nomination Committee's recommendation, the Board of Directors will consider the information and factors considered by the Governance and Nomination Committee and such additional information and factors as the Board of Directors deems relevant.

Any director nominee who offers his or her resignation for consideration pursuant to our Corporate Governance Guidelines will not participate in the Governance and Nomination Committee or Board of Directors deliberations regarding whether to accept the director nominee's offer to resign.

Risk Management

The Board is responsible for the oversight of our policies, procedures and systems in place to manage our risk exposure. Our Chief Executive Officer and Chief Financial Officer are responsible for the assessment and management of our risks and regularly report their findings to our Board directly or through their communications with our Audit Committee. Our Corporate Risk Manager is responsible for identifying, assessing and monitoring risks inherent to our business and providing guidance to senior management and our Audit Committee regarding our enterprise risk management, insurance portfolio, business continuity programs, crisis management, claims management and governance, record retention, and risk and compliance initiatives. Our Director of Internal Audit also reports risks that are identified during the internal audit process and our Information Technology Security Team reports on the risks associated with our information technology systems. After gathering and assessing information about our risk exposure, our Audit Committee reports the results of its review to the Board on a regular basis.

Other committees of the Board have risk oversight responsibility as well. The Governance and Nomination Committee is responsible for the oversight of risks associated with succession planning and corporate governance matters, and the Compensation Committee is primarily responsible for the oversight of risks associated with employment agreements, compensation arrangements and the attraction and retention of qualified employees. The Chairs of both the Governance and Nomination Committee and the Compensation Committee report the results of their meetings and reviews to the Board on a regular basis.

Our Lead Independent Director promotes effective communication and consideration of matters presenting significant risks to us through his role in coordinating with our Executive Chairman and Chief Executive Officer on meeting agendas, advising committee chairmen, chairing meetings of the independent directors and communicating between the independent directors, our Executive Chairman and our Chief Executive Officer.

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee has adopted a writtenpolicy that requires advance approval of all audit services, audit-related services, tax services and other services performed by our independent registered public accounting firm. The policy provides for pre-approval by the Audit Committee of specifically defined audit and permissible non-audit services. Unless the specific service has been pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent registered public accounting firm is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to pre-approve permitted services under $20,000 provided that the Chair reports any decisions to all members of the Audit Committee at the earliest convenience. In the event the Chair is unavailable, the remaining members must unanimously approve any request for permitted services, not to exceed $20,000, and notify the Chair at the earliest convenience.

Policy for Accounting Complaints

The Audit Committee has established procedures for (i) the receipt, retention and processing of complaints related to accounting, internal accounting controls and auditing matters, and (ii) the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters. The Audit Committee has contracted with a third party to provide a toll-free telephone number and internet service that is

-18-

staffed 24 hours a day, seven days a week. This service documents the complaint, assigns a reference number to the complaint for tracking purposes and forwards that information, through email, to the Audit Committee Chair and the Director of Internal Audit. In the event the complaint concerns an internal audit matter, only the Audit Committee Chair is notified. Either the Audit Committee Chair or Director of Internal Audit, using whatever resources are required, investigates the complaint. Corrective action, if deemed necessary, is decided upon by the Audit Committee Chair and then implemented as needed. The identity of the individual submitting the complaint and the details of the complaint remain anonymous throughout this process. We periodically test this process to ensure that complaints are handled in accordance with these procedures.

Compensation Committee Interlocks and Insider Participation

The current members of the Compensation Committee are Messrs. Culp (Chair), Hanley, Suggs and Wray. None of the current members of the Compensation Committee has ever served as an officer or employee of our Company or had any relationship during the year ended December 31, 2017 that would be required to be disclosed pursuant to the SEC's Item 404 of Regulation S-K. No interlocking relationships exist between our current Board of Directors, executive officers or Compensation Committee and the board of directors or compensation committee of any other company.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires certain of our officers, directors and persons who own more than 10% of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Such officers, directors and shareholders are required by SEC regulations to furnish us with copies of all such reports that they file. Based solely on a review of copies of the reports filed with the SEC since January 1, 2017 and on representations by certain officers and directors, all persons subject to the reporting requirements of Section 16(a) filed the reports required to be filed on a timely basis.

REPORT OF AUDIT COMMITTEE

The Audit Committee oversees our financial reporting, internal controls and audit functions on behalf of the Board of Directors and operates under a written charter, which is reviewed on an annual basisand was most recently revised on May 17, 2017. The Audit Committee is comprised solely of independent directors as defined by SEC rules and regulations and Nasdaq listing standards. Three of the four members of the Audit Committee, including the Chair, have been designated as “audit committee financial experts” as that term is defined by SEC rules and regulations. The Chair reports the Audit Committee's actions and deliberations to the Board at quarterly scheduled Board meetings.

During the fiscal year ended December 31, 2017, the Audit Committee fulfilled its duties and responsibilities as outlined in the charter. Among its actions, the Audit Committee:

• reviewed and discussed our quarterly earnings releases and the quarterly financial statements filed on Forms 10-Q with the SEC, with management and our independent registered public accounting firm, EY;

• reviewed with management, the internal auditor and EY the audit scope and plan for the audit of the fiscal year ended December 31, 2017; and

• met with the internal auditor and EY individually, outside the presence of management, to discuss, among other things, our financial disclosures, accounting policies and principles and internal controls.

In fulfilling its oversight responsibilities, the Audit Committee also reviewed and discussed the audited financial statements in the Annual Report on Form 10-K with management. The Audit Committee also has reviewed and discussed with management and EY management’s assessment of the effectiveness of our internal control over financial reporting and EY’s evaluation of our internal control over financial reporting.

The Audit Committee has discussed with EY the matters required to be discussed by Auditing Standard 1301, Communications with Audit Committees, issued by the Public Company Accounting Oversight Board (the “PCAOB”). In addition, the Audit Committee has received the written disclosures and the letter from EY required by

-19-

applicable requirements of the PCAOB regarding EY's communications with the Audit Committee concerning independence, and has discussed with EY that firm's independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2017 for filing with the SEC.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

Our guiding principles in the development of our executive compensation philosophy have been to align executive compensation with both our business objectives and the interests of our shareholders. We have attempted to balance the principal elements of our compensation program (base salary, short-term performance-based pay and longer-term incentives) to motivate our executives to achieve our short-term financial objectives as well as our long-term objectives of increasing our market share and shareholder value, which is substantially dependent on our achievement of our short-term objectives. We believe a significant portion of executive compensation should be based upon performance, and we have designed our elements of compensation accordingly. We do not believe the elements of our executive compensation program encourage excessive risk-taking, and we and our Board review our program periodically to ensure it is operating in accordance with our objectives.

Our executive compensation program ties a significant portion of current cash compensation directly to corporate performance primarily through the Performance Incentive Plan (the “PIP”). As described below, the PIP provides for monthly bonuses of a specified percentage of our monthly pre-tax income to the plan participants, subject to a minimum profitability threshold requirement. We believe this plan has been instrumental in motivating our named executive officers and other participating officers to consistently achieve and sustain superior profitability in our industry.

We believe long-term incentives are also necessary to align pay with performance, reward loyalty, and create shareholder value. As in 2016, all equity grants issued to named executive officers and other officers in 2017 were made under the Old Dominion Freight Line, Inc. 2016 Stock Incentive Plan (the “2016 Plan”), our primary plan for equity-based incentive compensation. Equity grant levels are tied to performance requirements, with any earned shares provided in the form of restricted stock subject to continued service vesting provisions to further enhance retention. Other elements of our executive compensation program include employee deferrals of short-term cash compensation into our Nonqualified Deferred Compensation Plan and contributions to our 401(k) retirement plan, which are also described in more detail below.

The principal factors in the Compensation Committee’s executive compensation decisions for 2017 were our financial performance, the relationship of executive compensation to the Company’s pre-tax income, the amount of compensation that is performance-based, and the review and analysis conducted by its independent compensation consultant.

The Company ended 2017 with strong growth in revenue, an industry-leading operating ratio, and a strong balance sheet, which we believe will strategically position us for growth in 2018. As a result, the Compensation Committee approved an increase of 3.0% in the base salaries for our named executive officers effective in January 2018. This increase followed an earlier increase of approximately 3.0% provided to non-officer employees effective in September 2017. In keeping with our philosophy of pay-for-performance, PIP payments to our named executive officers increased in 2017 as compared to 2016, as these payments were directly aligned with our financial performance. As a result, total annual cash compensation for our named executive officers as a group increased

-20-

20% in 2017 from 2016, which was consistent with the 20% increase in the Company’s income before taxes for the same period.

Objectives of Our Executive Compensation Program

Our executive compensation program is designed to achieve the following objectives, consistent with the principles and philosophy outlined above:

• provide meaningful and competitive compensation opportunities with a primary emphasis on variable incentives to encourage superior corporate performance and long-term shareholder value creation;

• motivate and reward our executives to increase Company earnings; and

• promote and foster an environment of cooperation and “OD family spirit.”

We also believe it is critical that our executive compensation program is structured to:

• attract talented, knowledgeable and experienced executives, who are critical to our success in the highly competitive transportation industry;

• retain our executives so they can add further value in current and future roles by providing long-term incentives that reward loyalty, retention and growth in shareholder value; and

• provide a reasonable level of compensation protection to our executive officers to offset some of the risks of a change in ownership.

In 2017, we believe the strengthening economy and a favorable pricing environment, coupled with the discipline instilled across our organization by the named executive officers to remain committed to our yield philosophy during a period of tightening industry capacity, yielded strong financial results. We also delivered strong total shareholder returns for the one, three, and five-year periods ended December 31, 2017 that significantly outperformed the companies in our peer group. These results reinforce the determination by our Compensation Committee and Board of Directors that our executive compensation program is achieving its desired objectives.

Role of Compensation Committee and Independent Directors

The Compensation Committee is comprised entirely of independent directors, and this committee is charged with recommending to our Board the compensation of our Chief Executive Officer and determining the compensation paid to our other named executive officers. Additionally, the Compensation Committee makes recommendations to the Board regarding the adoption of, and changes to, our executive compensation plans.

David S. Congdon, our current Vice Chairman of the Board and Chief Executive Officer, has a significant role in the compensation-setting process, including:

• providing recommendations to the Compensation Committee on business performance targets and objectives;

• evaluating individual performance; and

• providing recommendations to the Compensation Committee for salary and equity or non-equity based awards.

Neither Earl E. Congdon, our current Executive Chairman, nor David S. Congdon participates in the Compensation Committee’s deliberations regarding his individual performance, salary level, non-equity incentive plan compensation or other compensation that may be granted to him.

The Compensation Committee has the authority to hire outside advisers, such as compensation consultants, to render guidance and assistance when the Committee deems it appropriate and advisable. The

-21-

Compensation Committee, at its discretion, determines both the frequency that outside consultants are engaged and the scope of work these consultants perform. Prior to selecting or receiving advice from a compensation consultant or other adviser, the Compensation Committee assesses the independence of such adviser and thereafter conducts an annual assessment of any potential conflicts of interest raised by the work of such adviser.

Role of the Compensation Consultant

Since 2013, the Compensation Committee has periodically engaged Pearl Meyer & Partners, LLC, an independent compensation consulting firm, to assist it with its review and analysis of executive and non-employee director compensation matters. The Compensation Committee initially selected and has continued to engage Pearl Meyer based primarily on its skill sets, strengths, professionals, industry knowledge and resources.

In July 2017, the Compensation Committee engaged Pearl Meyer to conduct a review and analysis of the Company’s executive compensation program for officers and a separate review and analysis of the Company’s non-employee director compensation program. With respect to the executive compensation program, Pearl Meyer conducted a competitive market review, business performance analysis, total shareholder return analysis and pay and performance alignment review. In conducting its analysis, Pearl Meyer determined that the same publicly-traded companies included in Pearl Meyer’s analysis conducted during 2016 continued to be appropriate, with the exception of Roadrunner Transportation Systems, Inc., which was removed from the peer group given that company’s restatement of its prior period financial statements. As a result, the peer group consisted of the thirteen publicly-traded transportation companies listed below. Subsequent to Pearl Meyer’s peer group analysis, the previously announced merger of Knight Transportation, Inc. and Swift Transportation Company was completed in September 2017.

XPO Logistics, Inc.	Swift Transportation Company	Werner Enterprises, Inc.
J.B. Hunt Transport Services, Inc.	Landstar System, Inc.	Saia, Inc.
YRC Worldwide, Inc.	ArcBest Corporation	Ryder System, Inc.
C.H. Robinson Worldwide, Inc.	Expeditors International of Washington, Inc.	Hub Group, Inc.
Knight Transportation, Inc.

Following the peer group selection by the Compensation Committee, Pearl Meyer conducted a review and analysis of our executive compensation program, which would be considered by the Compensation Committee and the Board when making 2018 compensation decisions. With respect to our executive compensation program, Pearl Meyer was requested to review the competitiveness of the program and analyze recent business results in order to evaluate the strength of the relationship between pay and performance. Pearl Meyer’s analysis of our executive compensation program: (i) included each of our executive officer positions; (ii) focused on position level pay data (with respect to base salary, short-term incentives, total cash compensation, long-term incentives and total direct compensation (sum of base salary, short-term incentives and long-term incentives)); and (iii) comparisons to market (based on publicly available proxy statements and further supplemented by published survey data).

Based on its review and analysis, Pearl Meyer determined, among other things, that: (i) our aggregate total direct compensation levels were above the 75th percentile of the market; (ii) our performance was above the 75th percentile results for the thirteen publicly-traded transportation companies identified above based on a variety of financial and stockholder metrics over multiple time periods; (iii) our executive pay structure yields a much higher variable compensation mix as compared to market; and (iv) our executive compensation program continues to align pay and performance and receive strong shareholder support. For these reasons, Pearl Meyer did not recommend any changes to our executive compensation program.

The Compensation Committee has reviewed and considered the results of Pearl Meyer’s analysis and will continue to consider these results in making future compensation decisions. Although peer data is utilized in Pearl Meyer’s analysis, and the Compensation Committee reviews and considers such data in making compensation decisions, we do not benchmark compensation to any particular peer group percentile for any of our named executive officers. Given our strong financial performance, the large majority of total compensation for our named executive officers over the past several years has been delivered through the PIP. The Compensation Committee periodically reviews all aspects of our compensation program, including the pay mix for officers, to ensure alignment with desired objectives.

-22-

In connection with its engagement of Pearl Meyer, the Compensation Committee conducted a conflict of interest assessment and determined that Pearl Meyer was independent and that its engagement did not present any conflicts of interest. During fiscal 2017, Pearl Meyer only worked for the Compensation Committee and performed no additional services for the Company or any of the named executive officers. The Compensation Committee pre-approved all work performed by Pearl Meyer.

During fiscal 2017, neither the Compensation Committee nor our management used the services of any other compensation consultant other than Pearl Meyer.

Elements of Compensation

The following discusses each of the components of our executive compensation program and the decisions the Compensation Committee made in connection with 2017 and, where appropriate, 2018 compensation.

Annual Base Salary

Base salaries for our executives are designed to reflect job responsibilities and to provide competitive, fixed pay to balance performance-based risks. We have historically increased the base salaries of our named executive officers annually for an inflationary factor and, in some instances, an incremental adjustment attributable to our overall growth and financial performance. The Compensation Committee may also approve additional salary increases for certain officers, including certain named executive officers, when job performance, promotions and increased job responsibilities and/or other factors warrant. Base salaries have historically been positioned conservatively compared to companies in our peer group due to our executive compensation program’s primary emphasis on variable, performance-based incentives.

The Compensation Committee determined that our named executive officers should receive an increase in annual base salary of 3.0%, effective in January 2018. This followed an increase of approximately 3.0% for our non-officer employees that was effective in September 2017. The table below reflects the annual base salaries for our named executive officers that have been approved by the Compensation Committee for 2018, and the actual base salaries that were approved and paid in 2017 and 2016:

Named Executive Officer	2018 Base Salary (1) ($)	2017 Base Salary (1) ($)	2016 Base Salary (1) ($)
Earl E. Congdon (2)	630,895	612,519	594,679
David S. Congdon	630,895	612,519	594,679
Greg C. Gantt (3)	575,353	558,595	542,325
Adam N. Satterfield	283,635	275,374	267,353 (4)
Kevin M. Freeman	288,945	280,529	272,358

(1) The base salaries reported in this table and corresponding amounts reflected in the Summary Compensation Table may differ due to the timing of effective dates for base salary changes.

(2) As previously disclosed, effective May 16, 2018, Mr. Earl E. Congdon will transition to the role of Senior Executive Chairman, and his base salary will be reduced, effective June 1, 2018, to $400,000. See “Compensation Discussion and Analysis - Executive Leadership Team Transition” below.

(3) As previously disclosed, effective May 16, 2018, Mr. Gantt will transition to the role of President and Chief Executive Officer, and his base salary will be increased, effective June 1, 2018, to $650,000. See “Compensation Discussion and Analysis - Executive Leadership Team Transition” below.

(4) Mr. Satterfield’s 2016 annual base salary was increased from $228,989 to $267,353, effective July 1, 2016.

In approving the increases in base salary for our named executive officers that became effective in January 2018, the Compensation Committee considered the salaries of executive officers at peer companies, the 3.0% increase provided to non-officer employees in September 2017, the Company’s industry-leading financial results for 2017 and the Company’s outlook for 2018. Based on the data and analysis provided by Pearl Meyer, the base

-23-

salaries for most of our named executive officers are below the market median. The increases in base salaries were designed to maintain the current balance of base salary and performance-based and at-risk compensation for our named executive officers while also maintaining the desired level of competitiveness in compensation. As a result, and based on our strong financial performance throughout 2017, the Committee determined that the base salary adjustments for 2018 were appropriate for our named executive officers.

Non-equity Incentive Plan

The Compensation Committee has determined that the majority of compensation provided to our named executive officers should be performance-based. Accordingly, during 2017, our named executive officers participated with certain other employees in our PIP, which is an incentive cash bonus plan designed to incentivize participants to achieve the Company’s strategic and financial goals for the fiscal year, using a formulaic calculation. The PIP is administered by the Compensation Committee. Participants were selected by the Compensation Committee, with input by senior management, to receive a monthly cash incentive payment based upon a fixed percentage, or participation factor, of our pre-tax income if our pre-tax income exceeds 2% of revenue for that month. The Compensation Committee approved the participation factors for our named executive officers and other key participants and monitored the compensation derived from the PIP.

The material terms of the PIP were reapproved by our shareholders at our 2013 Annual Meeting. Shareholder approval enabled us to maximize our income tax deductions for compensation paid to certain employees under our cash incentive program pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”).

The formula applied for each participant in the PIP is shown below:

Monthly Income Before Income Taxes x Participation Factor = Monthly Payout

As a guideline for managing executive compensation, the Committee has determined that the majority of each named executive officer’s cash compensation should be performance-based, with base salary comprising the remaining portion of cash compensation. The PIP has been very effective in focusing our executive officers and other participants on continuous operational excellence and aligning pay with performance. Compensation earned under the PIP is “at risk” and performance-based, and will vary over time based on our profitability.

The Compensation Committee established the 2017 participation factor for each of our named executive officers at the same level as it was at year-end 2016. The following table shows the 2017 participation factors and the payouts earned by each of our named executive officers for each of 2017 and 2016:

Named Executive Officer	2017 PIP Participation Factor (%)	2017 PIP Payout ($)	2016 PIP Payout ($)
Earl E. Congdon (1)	1.04	6,090,369	4,966,908
David S. Congdon	1.04	6,090,369	4,966,908
Greg C. Gantt (2)	0.40	2,342,449	1,910,349
Adam N. Satterfield	0.20	1,171,225	955,175
Kevin M. Freeman	0.20	1,171,225	955,175

(1) As previously disclosed, effective May 16, 2018, Mr. Earl E. Congdon will transition to the role of Senior Executive Chairman, and his new PIP participation factor, effective June 1, 2018, will be decreased to 0.35%. See “Compensation Discussion and Analysis - Executive Leadership Team Transition” below.

(2) As previously disclosed, effective May 16, 2018, Mr. Gantt will transition to the role of President and Chief Executive Officer, and his new PIP participation factor, effective June 1, 2018, will be increased to 0.50%. See “Compensation Discussion and Analysis - Executive Leadership Team Transition” below.

The cash incentive provided by the PIP is determined on a monthly basis and paid to participants only if our pre-tax income exceeds 2% of revenue for that month. We met this minimum threshold of profitability for each

-24-

month in 2017, and as a result, our named executive officers received cash compensation from the PIP each month based upon their respective participation factor and our pre-tax income. In keeping with our philosophy of pay-for-performance, PIP payouts to our officers, including our named executive officers, in 2017 were directly aligned with the percentage increase in our pre-tax income.

The Compensation Committee recognizes that the PIP can produce higher-than-market cash compensation during periods of high profitability, including periods when our period-over-period performance may have declined. However, the PIP can also produce lower-than-market cash compensation during periods of low profitability, including periods when our period-over-period performance has improved and/or outperformed peers.

The Compensation Committee has considered whether our employee compensation policies and practices, including our PIP, create inadvertent incentives for executive management and other participants to make decisions that are reasonably likely to have a material adverse effect on us, and believes they do not. The Committee believes the overarching characteristic of the PIP is its ability to create a highly motivated and aligned management team that is focused on consistently executing our operating plan, improving our performance, and creating long-term value for our shareholders.

2016 Stock Incentive Plan

In 2016, as part of our ongoing commitment to review and assess the appropriateness and competitiveness of our executive compensation program, we determined to shift our equity compensation policy to allow for stock-settled awards. We believe stock-settled awards serve as a stronger incentive and retention tool and more closely align participant and shareholder interests than our historical phantom stock awards. To further this objective, the Compensation Committee and the Board adopted the 2016 Plan, which was subsequently approved by our shareholders at our 2016 Annual Meeting. The Compensation Committee has determined to grant restricted stock awards (“RSAs”) for shares of our common stock under the 2016 Plan to our named executive officers as well as other officers and members of the Board.

The 2016 Plan permits the grant of a broad array of equity award types, including RSAs, stock options and stock appreciation rights. The 2016 Plan authorizes the issuance of up to 2,000,000 shares of our common stock. Grants under the 2016 Plan are based on attainment of Company performance objectives, with no awards provided when results fall below a minimum performance threshold. The Compensation Committee generally determines the awards based on a percentage of annual base salary in relation to our operating ratio for the previous fiscal year. Operating ratio is a profitability measure used within the transportation industry and calculated by dividing total operating expenses by revenue. The Compensation Committee may approve an award under the 2016 Plan in an amount ranging from 0% up to 100% of an officer’s base salary for achieving a progressively lower operating ratio. No grants are made for an operating ratio greater than 95%. The Compensation Committee believes the underlying performance hurdles are challenging and would generally require us to perform at or above industry norms to earn grants in the upper half of the award opportunity range.

If the minimum performance threshold is met, any earned awards are provided in the form of RSAs that vest in equal annual installments over a period of three years, subject to continued employment, to further enhance executive retention and incentive. Vesting may also occur on the earliest of: (i) the date of a change in control of our ownership, which includes a “double trigger” and assumes the RSAs are not substituted, assumed, or continued; or (ii) the participant’s employment is terminated without cause or by the participant for good reason within six months before or one year after the effective date of the change of control; or (iii) the participant’s employment is terminated as a result of death or disability.

Our operating ratio continued to lead the LTL industry at 83.8%, 83.2% and 84.2%, for the years 2016, 2015, and 2014, respectively. To reward the achievement of these operating results, the Compensation Committee approved RSA grants under the 2016 Plan equal to 60% of each named executive officer’s annual base salary in May 2016 (considered compensation for fiscal year 2016) and January 2017 (considered compensation for fiscal year 2017). The number of shares awarded for each individual was calculated by dividing the cash value of the award by the 50-day moving average closing price of our common stock for the period ending on the trading day immediately preceding each grant date. The fair value at each grant date is calculated by multiplying the number of shares granted for each individual by the closing price of our common stock on such grant date. See "Executive Compensation - 2017 Grants of Plan-Based Awards" for more information about the 2017 RSA grants.

Named Executive Officer	Value of Restricted Stock Award At Grant ($)
	2017	2016
Earl E. Congdon	378,973	341,056
David S. Congdon	378,973	341,056
Greg C. Gantt	345,625	311,004
Adam N. Satterfield	170,366	131,333
Kevin M. Freeman	173,537	156,205

In 2017, our operating ratio improved by 110 basis points to 82.9%, once again leading the industry. As a result, each of our named executive officers earned RSA grants equal to 70% of base salary. Since the grants were made in February 2018, they will be included in tabular disclosures for fiscal 2018, based on current SEC reporting requirements.

Phantom Stock Plan

Prior to 2016, phantom stock awards were historically used to reward our named executive officers for creating shareholder value and to provide a long-term retirement incentive for our named executive officers. We do not provide a supplemental retirement plan for our named executive officers, although we do offer a voluntary, self-funded and unsecured deferred compensation program. See “Nonqualified Deferred Compensation Plan” below. These phantom stock awards were granted under the Old Dominion Freight Line, Inc. Phantom Stock Plan, as amended (the “2005 Phantom Stock Plan”), and the Old Dominion Freight Line, Inc. 2012 Phantom Stock Plan, as amended (the “2012 Phantom Stock Plan”, and together with the 2005 Phantom Stock Plan, the “Employee Phantom Stock Plans”). Each share of phantom stock awarded to eligible employees under the Employee Phantom Stock Plans represents a contractual right to receive an amount in cash equal to the fair market value of a share of our common stock on the settlement date, provided that vesting provisions have been satisfied.

All phantom stock awards not vested upon termination of employment are forfeited, although the Board of Directors has discretionary authority to modify or accelerate the vesting of awards. No shares of common stock will be issued upon settlement as these awards are settled in cash upon termination of employment. Because of the required vesting period and settlement provisions, this component of compensation generally facilitates the retention of key employees, rewards longevity and provides a retirement benefit to our named executive officers that is directly tied to shareholder value. Vesting and settlement provisions for each plan are discussed below.

Our Board of Directors approved, and we adopted, the 2005 Phantom Stock Plan in May 2005. The 2005 Phantom Stock Plan expired in May 2012; however, grants under this plan remain outstanding. Awards under the 2005 Phantom Stock Plan vest upon the earlier to occur of the following, provided the recipient is employed by us on such date: (i) the date of a change of control in our ownership; (ii) the fifth anniversary of the grant date; (iii) the date of the recipient’s death; (iv) the date of the recipient’s total disability; or (v) the date the recipient attains the age of 65. If termination of employment occurs for cause or prior to attaining the age of 55, all vested and unvested awards are generally forfeited unless the termination results from death or total disability or the Compensation Committee determines otherwise. Vested phantom stock awards are settled in cash upon the earlier of the recipient’s: (i) termination of employment on or after reaching 55 years of age for any reason other than death, total disability, or for cause; (ii) death while employed by us; or (iii) termination of employment as a result of total disability. Subject to restrictions under Section 409A of the Code, settlements are paid in 24 equal monthly installments.

Following expiration of the 2005 Phantom Stock Plan, our Board of Directors approved, and we adopted, the 2012 Phantom Stock Plan in October 2012. Under this plan, a maximum of one million shares of phantom stock may be awarded to eligible employees, subject to adjustment to prevent dilution or enlargement caused by changes in our outstanding shares of common stock. Each award vests in 20% increments on the anniversary of the grant date and is fully vested on the fifth anniversary of the grant date provided that the recipient: (i) has been continuously employed by us from the grant date until each respective vesting date; (ii) has been continuously employed by us for at least 10 years on the respective vesting date; and (iii) has reached the age of 65 on the respective vesting date. Vesting also occurs on the earliest of: (i) the date of a change in control of our ownership; (ii) the date of the recipient’s death; or (iii) the date of the recipient’s total disability, in each case provided that the recipient has been continuously employed by us from the grant date until the date of the respective event. Vested phantom stock awards are settled in cash on the settlement date, which is the earliest of the date of the recipient’s: (i) termination of employment for any reason other than death, total disability or for cause; (ii) death while employed

-26-

by us; or (iii) termination of employment as a result of total disability. Settlements are generally paid in 24 equal monthly installments, although recipients may, with respect to each grant, provide for payment in any other manner for up to five years following settlement subject to the limitations set forth in each individual award agreement. Each recipient also has the ability to defer the annual installments payable under an award agreement for a period of five years by filing a written election with the administrator at least one year in advance of the date on which payment of the annual installments would otherwise commence. Any payment may be delayed, if necessary, to comply with Section 409A of the Code.

As a result of the approval of the 2016 Plan, no phantom stock awards were issued in 2016 or 2017. The table below outlines the shares previously awarded under the 2012 Phantom Stock Plan for 2015 valued at grant date fair value. The number of shares awarded was calculated by dividing the value of each award by the 50-day moving average of a share of our common stock, with such averaging period ending on the trading day immediately preceding the grant date. The chart below is presented for historical reporting purposes and describes the phantom stock awards granted to our named executive officers in fiscal year 2015.

Named Executive Officer	2015 Value of Phantom Stock Award at Grant ($)
Earl E. Congdon	283,476
David S. Congdon	283,476
Greg C. Gantt	208,414
Adam N. Satterfield	(1)
Kevin M. Freeman	(1)

(1) Neither Mr. Satterfield nor Mr. Freeman was a named executive officer for the year ended December 31, 2015.

Stock Ownership Policy

The Compensation Committee strongly believes that our officers’ financial interests should be aligned with the long-term interests of our Company and its shareholders. To further this goal, the Compensation Committee has adopted a stock ownership and retention policy (the “Stock Ownership Policy”) applicable to members of the Board and officers of the Company. Each officer is required to achieve and maintain a level of ownership in our common stock based on a multiple of annual base salary as described below.

Covered Individuals	Base Salary Multiple Threshold
Chief Executive Officer	6.0x (600%) annual base salary
President and Chief Financial Officer	2.0x (200%) annual base salary
Other Executive Officers	1.5x (150%) annual base salary
All other Officers	1.0x (100%) annual base salary

For purposes of determining whether an officer has satisfied the Stock Ownership Policy, eligible equity may include: (i) shares owned by the officer; (ii) shares owned jointly with the officer’s spouse and/or dependent children; (iii) shares owned by the officer’s spouse or dependent children; (iv) shares held by the officer in a 401(k) plan; (v) shares held in individual brokerage accounts or other custodial accounts or in trust for the benefit of the officer or the officer’s spouse and/or dependent children; (vi) shares underlying time-based RSAs, restricted stock units, deferred stock units or similar awards (whether vested or unvested); (vii) shares received upon the exercise of stock options, stock appreciation rights or similar awards; and (viii) shares received upon the vesting or earning of performance awards. Shares of phantom stock awarded under the Employee Phantom Stock Plans are not considered eligible equity for purposes of determining compliance with the Stock Ownership Policy.

Officers may utilize grants under the 2016 Plan to satisfy the Stock Ownership Policy. Until the applicable thresholds of ownership outlined above are met, an officer is required to retain 50% of the net shares (those shares of common stock that remain after shares are sold, delivered, or withheld in payment of withholding taxes related to

-27-

equity awards) resulting from the vesting or earning of all RSAs granted under the 2016 Plan, and 50% of the net shares resulting from the exercise of any stock options granted under the plan.

Clawback Policy

The Compensation Committee and the Board believe it is desirable and in the best interests of the Company and its shareholders to maintain a culture of accountability and discourage conduct detrimental to the Company’s growth. To reinforce this objective, in July 2017, the Board of Directors adopted, upon the recommendation of the Compensation Committee, a clawback policy for the recovery of cash and equity incentive compensation from the Company’s officers and other employees deemed subject to the policy by the Board or the Compensation Committee. The policy provides that a covered individual may be required to forfeit or return to the Company all or a portion of any cash-based incentive compensation and/or equity-based incentive compensation received. Subject to the discretion of the Compensation Committee, reimbursement may be required (i) if such compensation was received based on quarterly or annual financial statements of the Company that are subsequently restated (other than due to changes in applicable financial reporting standards or under similar circumstances) in a manner that would decrease the amount of the compensation to which the covered individual was otherwise entitled, and (ii) such restatement is the result of, in whole or in part, the misconduct of the covered individual.

401(k) Retirement Plan

Our named executive officers may participate in our 401(k) retirement plan, which includes a matching provision that is based upon the participant’s contributions and, at our option, a discretionary contribution that is allocated to all 401(k) participants. Although we consider this match in our evaluation of overall compensation, we believe the maximum employee contribution and matching limits in our plan are, alone, insufficient to enable our named executive officers to save an amount that is adequate for their retirement or to be competitive with similarly-situated executives at other companies in our industry. As a result, we offer certain employees, including our named executive officers, the opportunity to participate in a non-qualified deferred compensation plan.

Nonqualified Deferred Compensation Plan

Because we do not provide a significant retirement plan for our named executive officers, we offer them an alternative vehicle for self-funding their retirement through our 2006 Nonqualified Deferred Compensation Plan. This plan allows eligible participants, including our named executive officers, to defer percentages of both their annual base salary and their monthly non-equity incentive compensation. The retirement benefits for our named executive officers are largely self-funded and unsecured, and the availability of these retirement benefits will depend on our ability to fund future payments. The plan is described in further detail under the caption “Executive Compensation - 2017 Nonqualified Deferred Compensation” in this proxy statement.

Tax Considerations

For tax years prior to January 1, 2018, Section 162(m) of the Code generally allowed us to deduct certain compensation paid to certain of our named executive officers under the Section 162(m) qualified performance-based compensation exemption. For taxable years beginning January 1, 2018, the qualified performance-based compensation exemption is no longer available, except in limited situations that are eligible for transition relief. Going forward, we will therefore not be eligible to take a full deduction under Section 162(m) for qualified performance-based compensation except in limited grandfathered situations, for which we may not qualify. The Compensation Committee may modify compensation that was initially intended to be exempt from Section 162(m), to the extent permitted by applicable law and the relevant governing documents, as well as its mix of compensation elements if it determines that such modifications are consistent with our business needs. Tax deductibility is one of many factors the Compensation Committee considers in evaluating executive compensation. We will continue to structure our executive compensation program to place primary emphasis on performance-based incentives that are intended to align pay with performance in support of long-term shareholder value creation.

Employment Agreements

We currently maintain employment agreements with Earl E. Congdon, currently our Executive Chairman of the Board, and David S. Congdon, currently our Vice Chairman of the Board and Chief Executive Officer. These employment agreements are designed to:

-28-

• establish non-competition and non-solicitation agreements, in order to limit our exposure to competition by any of these executives in the event of termination of his employment;

• provide long-term incentives to retain David S. Congdon and to ensure the continuity of leadership upon the retirement of Earl E. Congdon;

• provide protection to these executives in the event we experience a change in control; and

• limit our exposure to a sudden and significant drop in the market value of our common stock that could result from a liquidation of shares by the estate of these executives in the event of death.

Each agreement was tailored to address the competitive and financial exposures to both us and the employee referred to above. The terms and provisions of these agreements are described in more detail under the caption “Executive Compensation - Employment Agreements” in this proxy statement. See also “Compensation Discussion and Analysis - Executive Leadership Team Transition” below.

Change of Control and Post-Employment Benefit Considerations

The employment agreements for each of Earl E. Congdon and David S. Congdon provide for post-employment benefits that result from a change in control. In addition, David S. Congdon is entitled to receive post-employment benefits upon termination by us without cause or voluntary termination for “good reason.” A “change of control” does not constitute “good reason,” but a fundamental disagreement with the Board following a change of control does constitute “good reason.” The employment agreements, including post-employment benefits, are described in more detail under the caption “Executive Compensation - Employment Agreements” in this proxy statement.

The Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives, as amended, provides for post-employment benefits in the event of termination resulting from a change in control to eligible key executives, including three named executive officers: Greg C. Gantt, Adam N. Satterfield and Kevin M. Freeman. The benefits provided by this plan are described in more detail under the caption “Executive Compensation - Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives” in this proxy statement.

We believe that the employment agreements and the Change of Control Severance Plan for Key Executives provide a reasonable level of protection to our named executive officers in the event we experience a change of control. We also believe the post-employment benefits provided in the employment agreement for David S. Congdon are an effective incentive for retaining this key executive officer.

Other Benefits and Perquisites

Our named executive officers participate equitably, except as noted below, with all employees in our employee benefits, which include medical, dental, vision, short-term disability and group life insurance. Each named executive officer receives term-life insurance benefits insuring his life for $300,000, if under the age of 70, or $150,000, if over the age of 70. In addition, the employment agreement with David S. Congdon provides for the reimbursement of certain costs with respect to a $10,000,000 life insurance policy, subject to certain limitations. This benefit was granted to Mr. Congdon to protect us from a sudden and significant drop in the market value of our common stock that could result from a liquidation of shares by his estate in the event of his death. Earl E. Congdon has obtained, at his own expense, additional life insurance benefits that we deem adequate in mitigating this risk; therefore, no additional life insurance benefits were provided to him.

We provide basic employee group health and dental coverage for all employees but charge a premium for dependent and family coverage. We have waived the premiums for basic coverage for our named executive officers’ families, which are included in the “All Other Compensation” column of the Summary Compensation Table under the caption “Executive Compensation - Summary Compensation Table” in this proxy statement.

In 2017, we once again offered our officers, including our named executive officers, the opportunity to participate, on a voluntary basis, in an executive health program. For participants in this program, we paid the costs for a comprehensive health assessment to address their overall medical needs and assess their health risks. Mr. Earl Congdon, Mr. David Congdon and Mr. Freeman chose to participate in this program, and our cost for each was

-29-

$1,970, $2,100, and $3,687, respectively, which cost is included in the “All Other Compensation” column of the Summary Compensation Table under the caption “Executive Compensation - Summary Compensation Table” in this proxy statement. We plan to continue to provide this benefit for our officers, including our named executive officers, on an annual basis.

In 2017, Mr. Earl E. Congdon, Mr. David S. Congdon and Mr. Gantt elected to use a Company-provided vehicle, and Messrs. Satterfield and Freeman elected to receive a vehicle allowance provided by the Company. The taxable value of the personal use of these automobiles and applicable vehicle allowances is included in the “All Other Compensation” column of the Summary Compensation Table under the caption “Executive Compensation - Summary Compensation Table” in this proxy statement.

The employment agreements for Earl E. Congdon and David S. Congdon allow for personal use of our corporate aircraft. In 2017, personal use of our corporate aircraft by our named executive officers represented approximately 8.1% of the total hours that our aircraft were utilized. The incremental cost for the personal use of our corporate aircraft is included in the “All Other Compensation” column of the Summary Compensation Table under the caption “Executive Compensation - Summary Compensation Table” in this proxy statement. We do not provide any tax gross-up payments on any perquisites or benefits.

Executive Leadership Team Transition

Effective May 16, 2018, Earl E. Congdon will transition to the role of Senior Executive Chairman, David S. Congdon will transition to the role of Executive Chairman, and Greg C. Gantt will transition to the role of President and Chief Executive Officer. In connection with these transitions, we expect to enter into a third amendment to the amended and restated employment agreement with David S. Congdon, and Earl E. Congdon’s employment agreement will be permitted to expire in accordance with its terms on November 1, 2018. In addition, Mr. Gantt’s base salary will increase to $650,000 and Earl E. Congdon’s base salary will decrease to $400,000, each effective as of June 1, 2018. David S. Congdon’s base salary will remain the same. Also effective June 1, 2018, the participation factors for these officers in the PIP will be as follows:

Name	PIP Participation Factor (%)
Earl E. Congdon	0.35
David S. Congdon	1.04 (1)
Greg C. Gantt	0.50

(1) Mr. David Congdon’s current PIP participation factor was not changed in connection with his transition to Executive Chairman.

Advisory Vote on Executive Compensation

Since our 2011 Annual Meeting, we have conducted an advisory vote on the approval of compensation for our named executive officers each year at our annual meeting of shareholders. While this is a non-binding vote, we believe it is important for our shareholders to have an opportunity to vote on this proposal on an annual basis as a means to express their views regarding our executive compensation philosophy, our compensation policies and programs and our decisions regarding executive compensation, all of which are disclosed in our proxy statement. Our Board of Directors and Compensation Committee value the opinions of our shareholders and, to the extent there is any significant vote against the compensation of our named executive officers as disclosed in the proxy statement, we will carefully consider our shareholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns. In addition to our annual advisory vote on executive compensation, we are committed to ongoing engagement with our shareholders on executive compensation and corporate governance issues. These engagement efforts take place throughout the year through meetings, telephone calls and correspondence involving our senior management, directors and representatives of our shareholders.

At our 2017 Annual Meeting, 98% of the votes cast on the advisory vote to approve the compensation of our named executive officers were in favor of the proposal. Our Compensation Committee and our Board of Directors have considered the advisory vote results, and based in part on the high level of shareholder approval obtained at our 2017 Annual Meeting, continue to believe that our existing executive compensation program has been and

-30-

remains tailored to our business strategies, is consistent with our pay-for-performance philosophy, aligns executive and shareholder interests, reflects competitive pay practices, and appropriately rewards or penalizes our management team based on the level of financial success of our Company each year. Our strong, industry-leading financial performance in 2017 reinforces the view of our Compensation Committee and Board of Directors that our executive compensation program is achieving its desired objectives.

Nevertheless, we remain committed to periodically evaluating our executive compensation program to ensure that it remains competitive while also providing appropriate incentives for our management to create further shareholder value. In 2017, the Compensation Committee engaged Pearl Meyer to conduct a review and analysis of the Company’s executive compensation program for officers and a separate review and analysis of the Company’s non-employee director compensation program. Based on its review of our executive compensation program, Pearl Meyer concluded that our financial performance and total shareholder return continue to be strong (both on an absolute basis and relative to our competition) and that executive compensation was directionally aligned with our performance relative to our industry peers, and as a result, did not recommend any changes to our executive compensation program. Pearl Meyer also concluded that our executive compensation program continues to align pay with performance and reinforce our desired objectives. See “Compensation Discussion and Analysis - Role of the Compensation Consultant” above.

The Compensation Committee and the Board of Directors will continue to consider shareholders’ sentiments about our core principles and objectives and the analysis of Pearl Meyer when determining future executive compensation. As part of that commitment, we have determined that our shareholders should vote on a say-on-pay proposal each year, consistent with the preference expressed by our shareholders most recently at our 2017 Annual Meeting. Our Board of Directors unanimously recommends that you vote “FOR” Proposal 2 at the Annual Meeting. See “Proposal 2 - Approval, on an Advisory Basis, of the Compensation of our Named Executive Officers” in this proxy statement. Our shareholders will once again have the opportunity to express a preference on the frequency of say-on-pay votes at our 2023 Annual Meeting.

Conclusions

Our Compensation Committee has considered all of the elements of compensation described above and the objective of each element in determining the total amount of current compensation for our named executive officers. The Compensation Committee also considered whether our compensation policies and practices promote or encourage unnecessary and excessive risks and concluded they do not. Our compensation practices, which provide a balanced mix of short- and long-term incentives and use multiple performance metrics, together with our insider trading policy’s prohibitions on hedging and pledging of our securities, our stock ownership requirements and our recently implemented clawback policy, mitigate excessive risk-taking by our named executive officers. In addition, the Compensation Committee considered the review and analysis of our executive compensation program conducted by Pearl Meyer, which helped the Compensation Committee to reaffirm the Company’s compensation strategy and approach. The Compensation Committee believes the amount of each element of pay and the total amount of compensation for each named executive officer are reasonable and appropriate in light of the officer’s experience and individual performance, our operational and financial performance relative to our own expectations and the industry, and the officer’s role in creating shareholder value.

COMPENSATION COMMITTEE REPORT

The Compensation Committee of the Board of Directors has reviewed and discussed the above Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with our management.

(2) Includes the following: (i) the taxable excess group term-life insurance premiums under our group term-life insurance policy for all employees; and (ii) reimbursement of certain costs with respect to a $10,000,000 life insurance policy as further described under the caption “Executive Compensation – Employment Agreements – Employment Agreement with David S. Congdon” in this proxy statement.

(3) We offered our employees a choice in group health and dental plans that vary by the level of benefits available and premiums paid by the employee. Employee premiums for our basic group plans are waived for our named executive officers. If our named executive officers elect to enroll in plans with higher benefits and premiums, they are required to pay the difference in premiums between the basic plan and the more robust plan selected. The amount in the table reflects (i) the value of the basic group health and dental premiums that we waived for our named executive officers in 2017 ($2,899 for each of Mr. Earl Congdon, Mr. David Congdon, Mr. Gantt, and Mr. Freeman, and $3,536 for Mr. Satterfield); and (ii) our cost to provide to our named executive officers the opportunity to participate, on a voluntary basis, in an executive health program ($1,970 for Mr. Earl Congdon, $2,100 for Mr. David Congdon, and $3,687 for Mr. Freeman).

(4) For Messrs. Earl Congdon, David Congdon and Gantt, the amount reflects compensation for the personal use of a Company-provided vehicle calculated by allocating the fixed and variable costs of the vehicle over the percentage of personal versus total mileage driven. For Messrs. Satterfield and Freeman, the amount reflects compensation for a vehicle allowance in lieu of a Company-provided vehicle for 2017.

(5) Each of our named executive officers is eligible to participate in the Old Dominion 401(k) Employee Retirement Plan on the same basis as other employees. Employee contributions are limited to a percentage of their compensation, as defined in the plan. We guarantee a match of 30% of the first 6% of all employee contributions. Additional employer contributions may be awarded on a non-discriminatory basis to all participants at the discretion of our Board of Directors, and such discretionary employer contributions were awarded in 2017.

(6) Each participant in the 2016 Plan accumulates dividends for each unvested RSA. We paid one dividend of $0.10 per share before participants vested in one-third of the shares granted on May 26, 2017. Mr. Earl Congdon and Mr. David Congdon both vested 1,778 shares in 2017 and received a payment for their accumulated dividends of $178. Mr. Gantt vested 1,622 shares in 2017 and received a payment for his accumulated dividends of $162. Mr. Satterfield vested 685 shares in 2017 and received a payment for his accumulated dividends of $68. Mr. Freeman vested 815 shares in 2017 and received a payment for his accumulated dividends of $81. For more details, refer to the "2017 Stock Vested" table below.

(1) The 2017 grant of restricted stock reflects an award to the named executive officer equal to 60% of his base salary on the grant date divided by the average closing price of our common stock for the 50-day period beginning November 28, 2016 and ending February 8, 2017. Additionally, our Compensation Committee considers the value of the grant as part of the compensation in the year of grant when evaluating compensation to our named executive officers.

(2) The grant date fair value of restricted stock awards, computed in accordance with ASC 718, was determined by the number of shares set forth above multiplied by the grant date closing share price of $90.62, as reported on the Nasdaq Global Select Market.

(1) These unvested restricted stock awards under the 2016 Plan are scheduled to vest in accordance with the vesting provisions described in this proxy statement under “Compensation Discussion and Analysis - Elements of Compensation - 2016 Stock Incentive Plan".

(2) These unvested phantom stock awards under the 2012 Phantom Stock Plan are scheduled to vest in accordance with the vesting provisions described in this proxy statement under “Compensation Discussion and Analysis - Elements of Compensation - Employee Phantom Stock Plans." No shares of common stock may be issued pursuant to the 2012 Phantom Stock Plan, as the awards are required to be settled in cash.

(3) The market value of phantom stock awards and restricted stock awards that have not vested as of December 31, 2017 for each named executive officer is determined by multiplying the number of shares set forth above by the December 29, 2017 (the last business day of our fiscal year) closing share price of $131.55 as reported on the Nasdaq Global Select Market.

2017 Stock Vested

The following table displays vested stock awards to our executive officers that vested during 2017 under our Employee Phantom Stock Plans and the 2016 Plan, respectively.

		Stock Awards
Name	Award Type	Number of Shares Acquired on Vesting (#)	Value Realized on Vesting ($)
Earl E. Congdon(1)	Phantom Stock(2)	3,346.6	(4)
	Restricted Stock(3)	1,778.0	158,349
David S. Congdon	Phantom Stock(2)	12,322.6	(5)

Kevin M. Freeman	Phantom Stock(2)	5,436.4	(8)
	Restricted Stock(3)	815.0	72,584

(1) Earl E. Congdon attained the age of 65 while employed with us, and therefore, all of his awards under the 2005 Phantom Stock Plan vested prior to 2017. All phantom stock awards that vested in 2017 were granted under the 2012 Phantom Stock Plan.

(2) Participants are only entitled to receive cash amounts due for each vested share of phantom stock on the settlement date, which is distributed from our general funds. As a result, the value of the phantom shares vested during 2017, as well as prior-year vested phantom shares, is deferred until the settlement date. The value realized on the settlement date will be based on the fair market value of our common stock on such date as defined in the plans. Unless determined otherwise by the Compensation Committee, the settlement date generally is the earliest of: (i) the date of the participant's termination of employment on or after attaining age 55 (for awards under the 2005 Phantom Stock Plan), or age 65 (for awards under the 2012 Phantom Stock Plan), for any reason other than death, total disability, or for cause; (ii) the date of the participant's death while employed by us; or (iii) the date of the participant's termination of employment as a result of total disability.

(3) The value realized upon vesting of restricted stock awards is computed by the number of shares set forth above multiplied by the closing share price of $89.06 on the May 26, 2017 vesting date, as reported on the Nasdaq Global Select Market.

(4) The market value of phantom shares that vested during 2017 for Earl E. Congdon was $440,245, as determined by multiplying the number of phantom shares that vested in 2017 set forth above by the December 29, 2017 closing share price of $131.55 as reported on the Nasdaq Global Select Market. The market value of Earl E. Congdon's total 65,221.8 vested phantom shares at year-end 2017 was $8,579,928.

(5) The market value of phantom shares that vested during 2017 for David S. Congdon was $1,621,038, as determined by multiplying the number of phantom shares that vested in 2017 set forth above by the December 29, 2017 closing share price of $131.55 as reported on the Nasdaq Global Select Market. The market value of Mr. David Congdon's total 58,136.6 vested phantom shares at year-end 2017 was $7,647,863. Mr. David Congdon is under the age of 65; therefore, Mr. David Congdon has 10,819.8 vested shares under the 2012 Phantom Stock Plan that remain subject to the forfeiture provisions.

(6) The market value of phantom shares that vested during 2017 for Mr. Gantt was $1,191,922, as determined by multiplying the number of phantom shares that vested in 2017 set forth above by the December 29, 2017

-36-

closing share price of $131.55 as reported on the Nasdaq Global Select Market. The market value of Mr. Gantt's total 36,513.2 vested phantom shares at year-end 2017 was $4,803,305. Mr. Gantt is under the age of 65; therefore, Mr. Gantt has 7,955.4 vested shares under the 2012 Phantom Stock Plan that remain subject to the forfeiture provisions.

(7) The market value of phantom shares that vested during 2017 for Mr. Satterfield was $368,432, as determined by multiplying the number of phantom shares that vested in 2017 set forth above by the December 29, 2017 closing share price of $131.55 as reported on the Nasdaq Global Select Market. The market value of Mr. Satterfield's total 5,340.3 vested phantom shares at year-end 2017 was $702,516. Mr. Satterfield is under the age of 55; therefore, all vested shares under the 2005 Phantom Stock Plan and the 2012 Phantom Stock Plan remain subject to the forfeiture provisions.

(8) The market value of phantom shares that vested during 2017 for Mr. Freeman was $715,158, as determined by multiplying the number of phantom shares that vested in 2017 set forth above by the December 29, 2017 closing share price of $131.55 as reported on the Nasdaq Global Select Market. The market value of Mr. Freeman's total 22,515.2 vested phantom shares at year-end 2017 was $2,961,875. Mr. Freeman is under the age of 65; therefore, Mr. Freeman has 4,773.2 vested shares under the 2012 Phantom Stock Plan that remain subject to the forfeiture provisions.

2017 Nonqualified Deferred Compensation

The following table provides information regarding our named executive officers' contributions and earnings in our deferred compensation plans in 2017:

Name	Executive Contributions in Last FY ($)(1)	Registrant Contributions in Last FY ($)	Aggregate Earnings in Last FY ($)(2)	Aggregate Withdrawals/ Distributions ($)	Aggregate Balance at Last FYE ($)
Earl E. Congdon	—	—	907,974	—	7,935,234
David S. Congdon	—	—	1,268,351	—	8,812,807
Greg C. Gantt	—	—	64,880	233,015	1,494,643
Adam N. Satterfield	—	—	2,670	—	19,509
Kevin M. Freeman	—	—	35,861	252,013	797,497

(1) Contributions represent deferrals of certain amounts of salary and cash incentives awarded pursuant to our PIP, which are included in the "Salary" and "Non-Equity Incentive Plan Compensation" columns of the Summary Compensation Table. Our named executive officers did not defer any compensation for 2017.

(2) Aggregate earnings represent the return on the investment options selected by each named executive officer in 2017 in our deferred compensation plans. Earnings are not guaranteed rates of return and reflect actual market fluctuations of the funds in which they are deemed to be invested. These earnings are calculated in the same manner and at the same rate as earnings on externally managed funds or are based upon other market determined rates; therefore, participant earnings in the deferred compensation plans are not considered as above-market or preferential earnings and are not included in the Summary Compensation Table.

2006 Nonqualified Deferred Compensation Plan of Old Dominion Freight Line, Inc.

Effective January 1, 2006, we adopted the 2006 Nonqualified Deferred Compensation Plan of Old Dominion Freight Line, Inc. (the “Nonqualified Deferred Compensation Plan”) to permit certain of our management employees, including each of the named executive officers, to defer receipt of current compensation. This plan was amended and restated effective January 1, 2009, and further amended effective January 1, 2010, November 10, 2011 and January 29, 2015. The Nonqualified Deferred Compensation Plan is an unfunded plan maintained primarily for the purpose of providing retirement benefits for eligible employees. Participating employees may elect to reduce their (i) regular base salary by a whole number percentage from one to fifty percent and/or (ii) non-equity incentive compensation by a whole number percentage from one to seventy-five percent. The deferred amount is credited to the deferred compensation account we maintain for each participant. While not funded, each participant is allowed to select one or more investment options that mirror the actual performance of publicly-traded funds. Deferral amounts, along with gains and losses on investment options in which participants are deemed invested, are posted to the deferred compensation account of each participant. The total deferrals, plus the cumulative gains and losses on the investment options, are eligible for distribution from our general corporate funds. Distributions are subject to elections made by the participants, which generally require a five-year waiting period for active employees; however, distributions can begin immediately in the event of retirement, disability, death or other termination of service. Distributions also may be made upon the occurrence of certain other events, such as an unforeseeable emergency, or delayed under certain circumstances, such as when a distribution might violate the terms of a Company borrowing agreement. Payments are made from the Nonqualified Deferred Compensation Plan in a lump sum or in annual installments over a certain term, as elected by the participant. The plan also allows us, in our sole discretion and without any participant discretion or election, to make a mandatory lump-sum payment in settlement of a participant's entire accrued benefit.

Prior to the adoption of the Nonqualified Deferred Compensation Plan, we offered a similar plan allowing participating employees to defer receipt of regular base salary and/or cash incentive compensation. The deferral of wages earned subsequent to December 31, 2004 is no longer permitted under this plan, as required by Section 409A of the Code.

Potential Payments Upon Termination or Change of Control

Potential payments and benefits upon termination without cause, which includes resignation, retirement, death and total disability, or change of control, are provided to our named executive officers pursuant to (i) the provisions of Earl E. Congdon's and David S. Congdon's employment agreements (to the extent applicable), (ii) the Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives (to the extent applicable), (iii) our Employee Phantom Stock Plans and (iv) our 2016 Plan. All payments and benefits are forfeited if termination of the named executive officer resulted (i) for cause, (ii) from failure to comply with the non-competition and non-solicitation provisions of the respective plan and/or agreement, or (iii) from termination by the executive for a reason not constituting “good reason.” A “change of control” does not constitute “good reason,” but a fundamental disagreement with the Board following a change of control does constitute “good reason.” The employment and severance agreements are discussed in further detail under “Employment Agreements” and “Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives” below.

Earl E. Congdon's employment agreement provides for a payment equal to three times the sum of his base salary before a triggering event plus the annual bonus under the PIP paid to him for the preceding calendar year. This estimated amount is payable in a lump sum and due only if his employment is terminated: (i) by our exercise of a 120-day notice exception; (ii) by Mr. Congdon for “good reason” as defined in the agreement; or (iii) as a result of the expiration of the employment agreement on November 1, 2018; and such termination occurs within 12 months after a change of control. There would be no payment upon termination if Mr. Congdon's employment is terminated as described above and such termination does not occur within 12 months of a change in control (or, in the case of a termination for “good reason” due to a fundamental disagreement with the Board, within three years after a change in control), or Mr. Congdon's employment is terminated at any time due to his resignation, retirement, death or total disability or by us for cause. In connection with Mr. Congdon’s transition to Senior Executive Chairman effective May 16, 2018, Mr. Congdon’s employment agreement will be permitted to expire in accordance with its terms on November 1, 2018. There will be no payment to Mr. Congdon in connection with this expiration of his employment agreement.

David S. Congdon's employment agreement provides for three years of salary continuation, calculated by averaging the highest three years of base salary and annual bonus paid under the PIP within the previous five years prior to a triggering event. The settlement provisions of this agreement are further described in the “Employment Agreements” section below.

Pursuant to the Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives, our other named executive officers are entitled to three times the sum of the executive's base salary in effect immediately before the triggering event and the average of cash incentives paid under the PIP in the preceding three full calendar years. This estimated amount is payable over the compensation continuance period on the normal payroll payment schedule for salaried employees and due only if the executive's employment is terminated within 12 months of a change of control, and is reduced to two-thirds of this amount if terminated within 13 to 24 months of a change in control and is further reduced to one-third of this amount if terminated within 25 to 36 months of a change in control. There would be no payment upon termination of employment for resignation, retirement, death, total disability or by us for cause.

Our named executive officers, or their beneficiaries, would also receive payments due to them at retirement, death or disability pursuant to our non-discriminatory 401(k) retirement plan, our Employee Phantom Stock Plans, our 2016 Plan and our deferred compensation plans. The vested amounts due to each named executive officer under our Employee Phantom Stock Plans, under our 2016 Plan and under our deferred compensation plans are provided under the captions “Executive Compensation - 2017 Phantom Stock Vested,” “Executive Compensation - 2016 Stock Incentive Plan," and “Executive Compensation - 2017 Nonqualified Deferred Compensation” in this proxy statement.

Below is a table showing the amount of post-employment compensation and benefits that would be provided to each named executive officer due to a termination of employment or a change in control of the Company,

-38-

assuming that the triggering event occurred on December 31, 2017. The amounts in the table below do not include payments for compensation and benefits earned prior to the triggering event or gross-ups for excise taxes.

(1) Pursuant to our Employee Phantom Stock Plans and our 2016 Plan, previously unvested awards of phantom stock and unvested awards of restricted stock would be accelerated upon termination of service without cause in the case of death or total disability for each of our named executive officers (calculated using the number of unvested shares and awards multiplied by the closing share price of our common stock of $131.55 at December 29, 2017, as reported on the Nasdaq Global Select Market).

(2) David S. Congdon, upon termination without cause, would also receive payments and benefits provided for under the provisions of his employment agreement of $17,936,335 and welfare benefits of $34,339 (welfare benefits are not provided if the termination of service results from death).

(3) A change in control, without termination of service for the named executive officers, provides for the accelerated vesting of: (i) previously unvested awards of phantom stock pursuant to our Employee Phantom Stock Plans; and (ii) only in the event such awards are not assumed or substituted by the surviving company, unvested awards of restricted stock pursuant to our 2016 Plan. The amounts in the “Without Termination of Service” column are calculated using the number of each named executive officer's unvested shares multiplied by the closing share price of our common stock of $131.55 at December 29, 2017, as reported on the Nasdaq Global Select Market. The amounts in the “With Termination of Service” column reflect acceleration of previously unvested awards of restricted stock under the 2016 Plan for each named executive officer in the event of a change of control if (i) such awards are not assumed or substituted by the surviving company, or (ii) his employment is terminated by the Company not for cause or by him for good reason within specified time periods (even if such awards are assumed or substituted by the surviving company).

(4) Earl E. Congdon, upon a change in control with termination of service, would receive payments and benefits provided for under the provisions of his employment agreement of $20,108,664.

(6) Greg C. Gantt, upon a change in control with termination of service, would receive payments and benefits provided for under the provisions of the employee severance agreement of $7,797,699 and welfare benefits of $34,339. Pursuant to our Employee Phantom Stock Plans, his previously unvested awards of phantom

Employment Agreements

We currently have employment agreements with Earl E. Congdon and David S. Congdon, which were approved by the Board of Directors based on the recommendation of the Compensation Committee. Each agreement requires the executive to perform duties customarily performed by a person holding his respective position and to perform other services and duties reasonably assigned to the executive from time to time.

In connection with the executive leadership team transition discussed above under “Compensation Discussion and Analysis - Executive Leadership Team Transition,” effective May 16, 2018, Mr. Gantt will serve as our President and Chief Executive Officer, David S. Congdon will serve as our Executive Chairman, and Earl E. Congdon will serve as our Senior Executive Chairman. In connection with these transitions, we intend to enter into a third amendment to the amended and restated employment agreement with David S. Congdon and we intend to allow Earl E. Congdon’s second amended and restated employment agreement to expire in accordance with its terms on November 1, 2018.

Employment Agreement with Earl E. Congdon

The second amended and restated employment agreement with Earl E. Congdon, as amended, entitles him, while employed by us, to: (i) receive a base salary to be reviewed annually in accordance with standard payroll practices and procedures applicable to our executive officers; (ii) participate in the PIP; (iii) participate in any of our other bonus or incentive plans (whether in existence on the date of the employment agreement or later established) in which our other senior executives are entitled to participate; (iv) receive a discretionary bonus if so awarded by the Board from time to time; (v) participate in certain other plans and benefits we offer to our senior executives generally; (vi) personal use of our corporate aircraft (in accordance with our general policy); and (vii) an automobile for personal and business use. Although the Board may also award a discretionary bonus to be paid in the manner specified by the Board at the time any such bonus is approved, no such bonuses were approved or paid during 2017.

Mr. Congdon's employment agreement shall continue until the earliest of: (i) November 1, 2018; (ii) the date of his death; (iii) the specified date of termination under either our or his exercise of a 120-day notice exception; (iv) the date of termination by the Company for cause; (v) the date he terminates his employment for Good Reason; or (vi) the date of termination resulting from his total disability.  “Good Reason” is generally defined as: (i) our material breach of any provision of the agreement; (ii) his failure to be elected or re-elected to the Board; (iii) a material reduction in his base salary or incentive bonus opportunities; (iv) the merger of the Company or transfer of a significant portion of its assets unless the successor assumes all of our duties and obligations under the agreement; (v) the assignment of duties to him inconsistent with his position in the Company; (vi) the exclusion of his participation in our employee benefit plans; (vii) the transfer of his primary work location to a location that is more than 30 miles from his current primary work location or the requirement that he relocate his principal residence more than 30 miles from his current primary work location; (viii) our requirement that he travel on Company business to a substantially greater extent than required immediately prior to the date of the agreement; or (ix) the occurrence of a Fundamental Disagreement. 

A “Fundamental Disagreement” is generally defined as a material disagreement between Mr. Congdon and the Board that occurs within three years after a Change of Control, concerns the strategic direction of the Company or another issue of fundamental importance to the Company and is deemed to be a Fundamental Disagreement by a majority of the members of the Board who are not also members of his family. 

Mr. Congdon is generally entitled to certain compensatory benefits under the agreement if his employment is terminated within 12 months of a Change of Control (other than a termination for cause or as a result of Mr. Congdon's death or total disability). Generally, a "Change of Control" is defined to be the earliest of: (i) the date any person or group of persons, directly or indirectly, becomes the beneficial owner of 35% or more of the combined voting power of our then outstanding shares of common stock (excluding Mr. Congdon, our employee benefit plans, and any member of Mr. Congdon's family unless a majority of the independent members of the Board determines that such family member's beneficial ownership creates a substantial threat to corporate policy and effectiveness); (ii) the date when individuals who at the beginning of any two-year period constitute the Board, plus new directors whose nomination or election was approved by at least two-thirds of the directors still in office who were directors at the beginning of the two-year period, cease for any reason during the two-year period to constitute at least two-thirds of the members of the Board; (iii) the date of an equity transaction that would result in our voting securities

-41-

immediately prior to the transaction representing less than 60% of the combined voting power of the Company or a surviving entity immediately after the transaction; (iv) the date of a complete liquidation or winding-up of the Company; (v) the date of the sale or disposition of all or substantially all of our assets; or (vi) the date of our bankruptcy filing.

If Mr. Congdon's employment is terminated by the Company by exercise of the 120-day notice exception, by Mr. Congdon for Good Reason, or as a result of the expiration of the term on November 1, 2018, and such termination occurs within 12 months after a Change of Control (or, in the case of a termination for Good Reason due to a Fundamental Disagreement, within three years after the Change of Control), he is entitled to receive a lump sum payment of any compensation due but not yet paid through the termination date plus a payment equal to three times the sum of (i) his annual base salary in effect at that time and (ii) the annual bonus paid to him for the preceding calendar year under the PIP. 

If Mr. Congdon's employment is terminated as described above and such termination does not occur within 12 months after a Change of Control (or, in the case of a termination for Good Reason due to a Fundamental Disagreement, within three years after the Change of Control), or Mr. Congdon's employment is terminated at any time due to his death or total disability or by the Company for cause, he is only entitled to receive in a lump sum any compensation due but not yet paid through the termination date. 

Any amounts payable to Mr. Congdon in connection with his termination will be paid on the first day of the seventh calendar month following the calendar month in which his termination occurs as required by Section 409A of the Code. If Mr. Congdon terminates his employment for Good Reason or we terminate him for cause, each party generally will have 30 days after the receipt of the notice of termination to cure the reason given in the notice.  In the event that such cure is timely and to the satisfaction of the parties, the notice of termination would become null and void.

Mr. Congdon is also subject to a non-competition and non-solicitation clause, which covers the term of his employment plus the twenty-four month period following his termination of employment. In addition, Mr. Congdon's bonus, incentive and/or equity-based compensation paid to him under or pursuant to the terms of the employment agreement or any other plan or program of the Company will be subject to any recoupment, "clawback" or similar policy adopted by the Board after the date of the employment agreement.

In connection with Mr. Congdon’s transition to Senior Executive Chairman effective May 16, 2018, Mr. Congdon’s employment agreement will be permitted to expire in accordance with its terms on November 1, 2018. There will be no payment to Mr. Congdon in connection with this expiration of his employment agreement.

Employment Agreement with David S. Congdon

The amended and restated employment agreement with David S. Congdon, as amended, entitles him, while employed by us, to: (i) a base salary, to be reviewed annually in accordance with standard payroll practices and procedures applicable to our executive officers; (ii) participate in the PIP, any of our other bonus or incentive plans (whether in existence at the date of the employment agreement or later established) in which our other senior executives are entitled to participate and certain other plans and benefits we offer to our senior executives generally; (iii) a discretionary bonus as determined by the Board; (iv) the personal use of our corporate aircraft (in accordance with our general policy); (v) an automobile for personal and business use; and (vi) receive a life insurance benefit that provides him and his family with up to $10,000,000 in coverage at preferred rates.

This agreement provides for a term that continues until the earliest of: (i) the death of the executive; (ii) written notice by the executive or us of a desire to terminate, subject to a 90-day notice requirement; (iii) termination for cause; (iv) termination by the executive for “Good Reason,” which is generally defined above under “Employment Agreement with Earl E. Congdon”; or (v) termination resulting from total disability. Unless written notification is provided by Mr. Congdon or us, the term is automatically extended on the first day of each month for one additional calendar month, unless Mr. Congdon or we desire to fix the term for a definite three-year period.

If termination of the employment of Mr. Congdon, either voluntarily or by us, results in a compensation continuance termination event, Mr. Congdon is entitled to receive his base salary through the last day of the month of termination and, for the three-year period following termination, an annual amount equal to the average of Mr. Congdon's base salary and his annual bonus under our non-equity incentive plan for the three calendar years within

-42-

the five calendar-year period preceding termination that produces the highest average annual compensation. A compensation continuance termination event is defined in the employment agreement to mean termination due to: (i) our exercise of a 90-day notice exception; (ii) Mr. Congdon's total disability; (iii) Good Reason; or (iv) the expiration of a three-year term after being fixed by us. If the excise tax under Section 4999 of the Code would apply to such payments, they will be reduced or otherwise adjusted so that the excise tax will not apply. Mr. Congdon's final average compensation payable during the first six months of the compensation continuance period shall be paid to him in a lump sum as of the first day of the seventh calendar month of the compensation continuance period. During such period, he will also receive continued coverage under our medical, dental, vision and life insurance benefit programs. If the termination does not result in a compensation continuance termination event, Mr. Congdon is due only his base salary through the last day of the month in which the termination date occurs.

Mr. Congdon is also subject to a non-competition and non-solicitation clause, which covers the term of his employment plus the twenty-four month period following his termination of employment. In addition, Mr. Congdon’s bonus, incentive and/or equity-based compensation paid to him under or pursuant to the terms of the employment agreement or any other plan or program of the Company will be subject to any recoupment, “clawback” or similar policy adopted by the Board after the date of the employment agreement.

Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives

On May 16, 2005, the Board approved and we adopted the Old Dominion Freight Line, Inc. Change of Control Severance Plan for Key Executives (the “Severance Plan”) for eligible key executives as determined by the Compensation Committee. Messrs. Gantt, Satterfield and Freeman are eligible key executives under the Severance Plan. Earl E. Congdon and David S. Congdon are parties to employment agreements that provide change of control and severance benefits as summarized above and, accordingly, do not participate in the Severance Plan. The Severance Plan was amended and restated effective January 1, 2009 to comply with Section 409A of the Code. Under the Severance Plan, termination of a participant's employment by us for any reason other than for cause, death or total disability, or by the participant for Good Reason occurring within 36 months following a change in control, entitles the participant to receive the following benefits: (i) receipt of base salary through the last day of the month in which the termination date occurs; (ii) a monthly benefit equal to the participant's monthly termination compensation, as defined in the Severance Plan, during the compensation continuance period; and (iii) continued participation in our welfare benefit plans until the earlier of the participant's death or the last day of the calendar month in which the participant receives his final payment of termination compensation. The compensation continuance period is equal to 12 calendar months plus three additional calendar months for each year of service completed by the participant as of the termination date in excess of 10 years, not to exceed 36 calendar months.

CEO Pay Ratio Disclosure

In August 2015, pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC adopted a rule requiring disclosure of the ratio of the median employee’s annual total compensation to the annual total compensation of the Chief Executive Officer (“CEO”). During the fiscal year ended December 31, 2017, our CEO was David S. Congdon. The pay ratio included below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K:

Median Employee annual total compensation	$67,657
CEO annual total compensation	$7,195,351
Ratio of CEO to Median Employee annual total compensation	106:1

In determining the median employee for 2017, a listing was prepared of all employees as of December 29, 2017.  The listing is comprised of all active employees including part-time and partial year employees, but excludes independent contractors and our CEO.  We used annual gross earnings for calendar year 2017 as the consistently applied compensation measure to identify the median employee and did not annualize compensation for partial year employees.  The median employee’s annual total compensation was calculated in accordance with the requirements of the Summary Compensation Table and includes: salary, bonus, and 401(k) employer matching contribution. SEC rules for identifying the median employee and calculating the pay ratio allow companies to use various methodologies and assumptions. As a result, our reported pay ratio may not be comparable to other companies’ pay ratios.

DIRECTOR COMPENSATION

2017 Compensation of Directors

The following table reflects compensation earned for services performed in 2017 by members of our Board of Directors who were not named executive officers:

Name	Fees Earned or Paid in Cash ($)	Stock Awards ($)(1)	All Other Compensation ($) (2)	Total ($)
John R. Congdon, Jr.	75,000	100,326	4,236	179,562
Robert G. Culp, III	105,000	100,326	1,649	206,975
Bradley R. Gabosch	75,000	100,326	4,849	180,175
Patrick D. Hanley	75,000	100,326	6,949	182,275
John D. Kasarda	85,000	100,326	1,649	186,975
Leo H. Suggs	75,000	100,326	1,649	176,975
D. Michael Wray	95,000	100,326	4,849	200,175

(1) Each non-employee director was awarded a grant of restricted stock on May 4, 2017, with the number of shares determined by dividing the target value of $100,000 by the 50-day average closing price of our common stock ($86.93) beginning February 22, 2017 and ending May 3, 2017. The grant date fair value of these awards, computed in accordance with ASC 718, was determined by multiplying the 1,150 shares of restricted stock underlying each award by the closing price of our common stock of $87.24 on the grant date of May 4, 2017, as reported on the Nasdaq Global Select Market. The value of each restricted stock award assumes that all shares will vest in accordance with the requirements of the 2016 Plan described in "Components of Compensation" below. As of December 31, 2017, the restricted stock award of 1,150 shares granted to each non-employee director on May 4, 2017 represented the only unvested shares for each non-employee director.

(2) The amount in the table reflects: (i) our contribution to a qualifying charitable organization, recognized as a tax-exempt organization under Section 501(c)(3) of the Code, made on behalf of the non-employee director ($1,000 for Mr. John Congdon, $1,500 for Mr. Culp, $1,500 for Mr. Gabosch, $1,500 for Mr. Hanley, $1,500 for Dr. Kasarda, $1,500 for Mr. Suggs and $1,500 for Mr. Wray); (ii) our cost to provide our non-employee directors with the opportunity to participate, on a voluntary basis, in an executive health program ($3,087 for Mr. John Congdon, $3,200 for Mr. Gabosch, $5,300 for Mr. Hanley, and $3,200 for Mr. Wray) and (iii) $149 of accumulated dividends on each non-employee director's restricted shares that vested in 2017. See the "Components of Compensation" section below for more information on vesting terms of the restricted stock granted to non-employee directors.

Components of Compensation

In 2017, the Compensation Committee engaged Pearl Meyer to evaluate the competitiveness of the compensation provided to our non-employee directors relative to the compensation arrangements provided to outside directors of comparable companies, including the publicly-traded companies in our selected peer group discussed above in "Compensation Discussion and Analysis - Role of the Compensation Consultant." Pearl Meyer found that our average total compensation per independent, outside director was below the median amounts reported by peer companies and survey data for comparable companies. Pearl Meyer developed various recommendations to increase the compensation of our outside, independent directors within the current structure to advance it to the median of peer company practices, taking into account the significant relevant experience of our directors, our sustained high performance compared to peers, and our need to attract and retain outside, independent directors with desired levels of experience.

-44-

The non-employee director compensation structure applicable for 2017 is provided below:

Director Role	Annual Cash Retainer Amount  ($)	Annual Restricted Stock Grant Amount ($)
Member (all non-employee directors)	75,000	100,000
Audit Committee Chair (1)	20,000	—
Compensation Committee Chair (1)	10,000	—
Governance and Nomination Committee Chair (1)	10,000	—
Lead Independent Director (1)	20,000	—

(1) Each non-employee Chair of a Board Committee and the Lead Independent Director receives an annual retainer for service as Chair of a Committee and/or as Lead Independent Director, which is in addition to the non-employee director retainer of $75,000.

Upon the recommendation of Pearl Meyer and the Compensation Committee, the Board determined that it would be in the best interests of the Company to increase the annual Board cash retainer for each non-employee director from $75,000 to $80,000 and increase the annual restricted stock grant value for each non-employee director from $100,000 to $120,000, each effective in connection with the Annual Meeting. Also upon the recommendation of Pearl Meyer and the Compensation Committee, the Board increased the Lead Independent Director cash retainer (from $20,000 to $25,000), the Audit Committee Chair cash retainer (from $20,000 to $25,000), the Compensation Committee Chair cash retainer (from $10,000 to $15,000) and the Governance and Nomination Committee Chair cash retainer (from $10,000 to $12,500), each effective in connection with the Annual Meeting.

The annual retainers, for both the Board and its Committees, are paid ratably at the end of each fiscal quarter. Directors receive reimbursement of certain business and travel expenses incurred in their capacities as directors. Otherwise, there is no additional compensation provided for attendance at in-person or telephonic meetings. As employees in 2017, Earl E. Congdon and David S. Congdon received no retainer or restricted stock awards for Board service.

Non-employee members of the Board are eligible to receive grants under the 2016 Plan. RSAs granted to non-employee directors under the 2016 Plan generally vest upon the earlier to occur of the following, provided the participant is still serving as a director: (i) the one-year anniversary of the grant date; (ii) the date of a change of control in our ownership; (iii) death; or (iv) total disability. Awards that are not vested upon termination of service as a director are forfeited. Each director is also subject to our Stock Ownership Policy and is required to achieve and maintain a stock ownership threshold equal to three times the annual Board cash retainer. The descriptions of eligible equity and treatment of grants under the 2016 Plan described above for officers also apply to directors. See “Compensation Discussion and Analysis - Stock Ownership Policy.”

-46-

historically had been primarily engaged in the business of leasing tractors, trailers and other vehicles as well as providing contract dedicated fleet services, was acquired by Penske Truck Leasing during the third quarter of 2017 (the “Penske Acquisition”).

In addition, we received $6,000 from Leasing for the rental of property in 2017.

Audit Committee Approval and Related Person Transaction Policy

Each of the foregoing transactions or series of transactions was reviewed and approved by the Audit Committee of our Board of Directors. In considering whether to approve such transactions, the Audit Committee determined that they were fair to us and that the terms and conditions of the transactions were substantially the same as, or more favorable to us than, transactions that would be available from unaffiliated parties. Any extensions, modifications or renewals of the foregoing transactions, or any new transactions that involve us and a related party, must be approved by the Audit Committee and must be on terms no less favorable to us than the terms that could be obtained in a similar transaction with an unaffiliated party in accordance with our written Related Person Transactions Policy.

Our Related Person Transactions Policy governs the procedures for review and consideration of all related person transactions in which we are a participant to help ensure that any such transactions are identified and given appropriate consideration. Generally, any financial transaction, arrangement or relationship in an amount exceeding $120,000 in which we are or would be a participant, and in which any related person, as defined by Item 404 of Regulation S-K under the Exchange Act, has or would have a direct or indirect material interest, is prohibited unless: (i) approved or ratified by the Audit Committee in accordance with the policy; (ii) approved by the Chair of the Audit Committee and ratified by the Audit Committee in accordance with the policy; or (iii) the transaction is of the type of pre-approved transactions listed in the policy. It is our policy to enter into or ratify such transactions only when the Board, acting through the Audit Committee, determines that the transaction is in, or is not inconsistent with, the best interests of the Company and our shareholders.

In conducting its review of any proposed related person transaction, the Audit Committee will consider all of the relevant facts and circumstances available to the Audit Committee, including, but not limited to: (i) whether the transaction was entered into in the ordinary course of business of the Company; (ii) the purpose of, and potential benefits to the Company of, the transaction; (iii) the approximate dollar value of the amount involved in the transaction, particularly as it relates to the related person; (iv) the related person’s interest in the transaction; (v) the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss; (vi) the impact on a director's independence in the event the related person is a director, an immediate family member of a director or an entity in which a director is a partner, shareholder or officer; (vii) the availability of other sources for comparable products or services; (viii) the terms available to unrelated third parties or to employees generally in an arms-length negotiation; (ix) required public disclosure, if any; and (x) any other information regarding the transaction or the related person that would be material to investors in light of the circumstances of the particular transaction. No member of the Audit Committee will participate in any review, consideration, approval or ratification of any related person transaction with respect to which such member or any of his or her immediate family members is the related person.

In accordance with the Related Person Transactions Policy, the Audit Committee will also perform an annual review of previously approved or ratified related person transactions that remain ongoing and have a remaining term of more than six months or remaining amounts payable to or receivable from the Company of more than $120,000, when aggregated with all other amounts received or paid. Based on all relevant facts and circumstances, the Audit Committee will determine if it is in our best interest to continue, modify or terminate any ongoing transaction, arrangement or relationship. Except as discussed above, since the beginning of our last fiscal year, no financial transactions, arrangements or relationships, or any series of them, were disclosed or proposed through our process for review, approval or ratification (as summarized above) with related persons in which the Company was or is to be a participant, the amount involved exceeded $120,000 and any related person had or will have a direct or indirect material interest.

PROPOSAL 2 - APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION

OF OUR NAMED EXECUTIVE OFFICERS

As required by Section 14A of the Exchange Act, we are providing our shareholders with the opportunity to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the compensation disclosure rules of the SEC (a "say-on-pay" vote). Taking into consideration the most recent voting results from our 2017 Annual Meeting concerning the frequency of the shareholder advisory vote to approve the compensation of our named executive officers, we determined that we will continue to hold an annual advisory vote to approve the compensation of our named executive officers until the next required advisory vote on the frequency of such votes.

Our financial results for 2017 reflect Company record increases in revenue, net income and earnings per diluted share. We believe our results were driven by the strengthening economy and a favorable pricing environment during a period of tightening industry capacity. Our consistent investments in our service center network and equipment have provided us with the capacity needed to serve our customers’ increasing freight demands and win market share. The increased freight density in our service center network and improvement in yield, combined with our continued focus on managing our variable costs, led to the 110 basis-point improvement in our operating ratio as compared to 2016. We believe the strength of our financial position was attributable to the execution of our strategic plan, which included key decisions made by our named executive officers. Furthermore, the review and analysis of our executive compensation program presented by Pearl Meyer to our Compensation Committee in October 2017 demonstrated that our program continues to align executive compensation with our performance, and that our program is well-aligned with our performance relative to our peers. Our exceptional financial performance in 2017 reinforces the views of our Compensation Committee and Board of Directors that our executive compensation program is achieving its objectives.

Highlights of our executive compensation program include the following:

• Pay-for-Performance

▪ Our PIP is designed to tie a significant portion of current cash compensation directly to corporate performance. PIP payouts are directly tied to changes in our profitability, ensuring that our executive compensation is aligned with our financial performance. Just as our PIP can produce higher-than-market cash compensation during periods of high profitability, including periods when our period-over-period performance may have declined, it can produce lower-than-market cash compensation during periods of low profitability, including periods when our period-over-period performance has improved and/or outperformed peers.

• Focus on Long-Term Success

▪ Historically, our compensation program provided for phantom stock awards designed to reward loyalty and the creation of shareholder value. These awards vest over five years but are not settled until retirement or termination of employment, which may be much later. The ultimate value of the award is linked directly to the value of our common stock. The 2016 Plan now serves as our primary equity incentive plan. It is important that our officers have financial interests that are aligned with the long-term interests of our Company and its shareholders.

• Alignment with Shareholder Interests

▪ Our compensation policies are designed to attract, motivate and retain key executives who are critical to our success.

▪ The PIP links a significant portion of executive compensation directly to our profitability.

▪ The RSAs under the 2016 Plan link a portion of executive compensation directly to Company performance and the creation of long-term shareholder value.

▪ Severance and change in control agreements do not include gross-ups for excise taxes.

-48-

▪ Our securities trading policy prohibits hedging or pledging of our securities by directors, officers and employees. The policy also prohibits directors, officers and employees from holding our securities in margin accounts or pledging our securities for a loan.

▪ Our Stock Ownership Policy subjects our directors, executive officers and other officers to minimum stock ownership and equity retention requirements.

▪ Our Clawback Policy, which was implemented in July 2017, maintains a culture of accountability and discourages conduct detrimental to our growth and financial performance by allowing the Company to recover cash and equity incentive compensation from our officers and certain other employees under specified circumstances.

We urge our shareholders to read the “Compensation Discussion and Analysis” section of this proxy statement for a more thorough discussion of our compensation philosophy, which is designed to align our key executives' compensation with both our business objectives and the interests of our shareholders. We also recommend that our shareholders review the application of our compensation philosophy and the elements of compensation provided to each named executive officer as reflected in the discussion and tables included under the caption “Executive Compensation” in this proxy statement.

For the reasons stated above, the Board recommends that our shareholders vote “for” the following advisory resolution at our Annual Meeting:

“RESOLVED, that the compensation paid to Old Dominion's named executive officers, as disclosed in the proxy statement for our 2018 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and related narrative discussion, is hereby APPROVED.”

To be approved, the number of votes cast “for” this advisory resolution must exceed the votes cast “against” this advisory resolution. Because this proposal is advisory, the results of the vote on this proposal will not be binding on our Board, Compensation Committee or our management. To the extent there is any significant vote against the compensation of our named executive officers as disclosed in this proxy statement, however, the Compensation Committee will evaluate whether any actions are necessary in the future to address those concerns.

PROPOSAL 3 – RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Ernst & Young LLP (as defined above, "EY") to serve as our independent registered public accounting firm for the year ending December 31, 2018. Although ratification is not required by our bylaws or otherwise, the Board of Directors is submitting the appointment of EY to the shareholders for ratification as a matter of good corporate governance. In the event the shareholders fail to ratify the appointment of EY, the Audit Committee will consider whether to appoint another independent registered public accounting firm for the year ending December 31, 2018. Representatives of EY are expected to be present at the Annual Meeting and will have an opportunity to respond to appropriate questions and to make a statement if they so desire.

To be approved, the number of votes cast “for” this proposal must exceed the votes cast “against” this proposal.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE

APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING
