OLD DOMINION FREIGHT LINE EARNS $0.48 PER DILUTED SHARE FOR

FOURTH QUARTER 2006

Operating Ratio Improves 70 Basis Points

Establishes Guidance for 2007 Earnings per Diluted Share to Range of $2.00 to $2.05

THOMASVILLE, N.C. (February 1, 2007) – Old Dominion Freight Line, Inc. (NASDAQ: ODFL) today announced financial results for the fourth quarter and twelve months ended December 31, 2006. For the quarter, revenue was $319.4 million, an increase of 12.0% from $285.2 million for the fourth quarter of 2005. Net income for the fourth quarter of 2006 rose 21.5% to $17.8 million from $14.7 million for the fourth quarter of 2005, and earnings per diluted share increased 23.1% to $0.48 from $0.39. Old Dominion’s operating ratio improved to 90.1% for the fourth quarter of 2006 from 90.8% for the fourth quarter of the prior year.

Revenues increased 20.5% for 2006 to $1.28 billion from $1.06 billion for 2005. Net income rose 35.7% to $72.6 million from $53.5 million. Earnings per diluted share for 2006 were $1.95, up 36.4% from $1.43 for 2005. Old Dominion’s operating ratio for 2006 improved to 89.8% from 90.8% for 2005.

Earl E. Congdon, Chairman and Chief Executive Officer of Old Dominion, remarked, “We are pleased with Old Dominion’s operating performance in the fourth quarter and resulting earnings per diluted share that exceeded our established guidance of $0.40 to $0.43. While our financial results reflect tonnage growth during the quarter that was slightly higher than anticipated, we attribute most of the earnings in excess of our guidance to a reduction in our effective tax rate and favorable experience in our reserves for insurance claims.

“Our total tons shipped increased 10.6% for the fourth quarter of 2006 as a result of a 12.7% increase in total shipments with a 1.8% decrease in weight per shipment. We view this decline in weight per shipment to be consistent with the economic environment during the fourth quarter that proved to be challenging. We experienced a sudden decline in daily tonnage in October; however, that trend stabilized in December.

“Old Dominion continues to produce the great majority of its revenues – 98% for 2006 – within its network of service centers that have been open for more than one year. As a result, we were able to

increase freight density and capacity utilization within our network that led to a 70 basis-point improvement in our operating ratio for the quarter. This continued improvement allowed the Company to finish 2006 with its annual operating ratio below 90.0% for the first time since becoming a public company in 1991.

“We added 28 new service centers to our network during 2006, including four in the fourth quarter, and completed 2006 with 182 service centers in operation. The four service centers added in the fourth quarter were Rockford, Illinois; Saginaw, Michigan; Bismarck, North Dakota; and Fort Worth, Texas. We now operate service centers in 47 states, up from 44 at the end of 2005, and provide full-state coverage in 37 of those states compared with 33 at the end of 2005. We intend to continue expanding our service center network, subject to real estate availability and market potential, to achieve our strategic goal of providing full-state coverage throughout the continental U.S. and to provide a platform for future growth.

“We were encouraged by our operating trends in the latter part of the fourth quarter, but we remain cautious in establishing our earnings guidance for 2007 due to the current economic environment and the severity of a number of winter storms that have already occurred. As a result, we are today establishing our guidance for earnings per diluted share for 2007 in a range of $2.00 to $2.05. In addition, the Company today established its earnings guidance for the first quarter of 2007 in a range of $0.32 to $0.35, compared with $0.35 for the first quarter of 2006. Through the consistent implementation of our long-term growth strategies throughout the economic cycle, we expect to continue producing profitable growth at a rate in excess of industry averages in 2007 and progressing toward our longer-term goal of $2 billion in revenue for 2010.”

Mr. Congdon concluded, “Old Dominion’s performance for the fourth quarter and for full-year 2006 again demonstrates the strength of our differentiated market position. In addition to our extensive service center network, which enables us to provide comprehensive, single-source products and services regionally and inter-regionally, our technology infrastructure and our flexible, non-union workforce all combine to drive a customer service culture and capability that is the basis for our success. We are confident in our ability to capitalize on market opportunities and to continue our long-term record of profitable growth in the years ahead.”
