Liquidity Disclosure [Policy Text Block]	2. LIQUIDITY Our business requires significant capital investments over the short-term and the long-term. Recently, we have financed our capital requirements with borrowings under our Third Amended and Restated Credit Facility ("Credit Facility"), cash flows from operations, long-term operating leases, capital leases, secured installment notes with finance companies and refunds of previously paid federal income taxes as a result of net operating loss carry backs pursuant to the Worker, Homeownership, and Business Assistance Act of 2009 in 2011 and 2010. Our primary sources of liquidity at December 31, 2011, were funds provided by operations, proceeds from the sale of used revenue equipment, borrowings under our Credit Facility, borrowings from secured installment notes, capital leases, operating leases of revenue equipment, and cash and cash equivalents. We had a working capital (total current assets less total current liabilities) deficit of $42.1 million and $30.8 million at December 31, 2011 and 2010, respectively. Working capital deficits are common to many trucking companies that operate by financing revenue equipment purchases through borrowing or capitalized leases. When we finance revenue equipment through borrowing or capitalized leases, the principal amortization scheduled for the next year is categorized as a current liability, although the revenue equipment is classified as a long-term asset. Consequently, each purchase of revenue equipment financed with borrowing or capitalized leases decreases working capital. Additionally, as discussed in Note 8, our Credit Facility is reflected as a current maturity while the outstanding debt is not due until September 2014. We believe our working capital deficit had little impact on our liquidity. Based on our expected financial condition, net capital expenditures, and results of operations and related net cash flows, we believe our working capital and sources of liquidity will be adequate to meet our current and projected needs for at least the next year. We do not expect to experience material liquidity constraints in the foreseeable future or on a long-term basis, based on our anticipated financial condition, results of operations, cash flows, continued availability of our Credit Facility, secured installment notes, and other sources of financing that we expect will be available to us. Our net capital expenditures are expected to be significantly less in 2012 than 2011 or 2010 as a result of the young age of our tractor fleet providing for less replacements in 2012, partially offset by a plan increase in the purchase of trailers. Additionally, we have increased the number of independent contractors in our fleet to 216 at December 31, 2011 from 138 at December 31, 2010. The majority of this increase came in the second half of 2011. We expect the trend of increased independent contractors as a percentage of our fleet to continue into 2012. We had $15.9 million in borrowings outstanding under the Credit Facility as of December 31, 2011, undrawn letters of credit outstanding of approximately $38.9 million, and available borrowing capacity of $27.6 million. Our intra-period borrowings under the Credit Facility have ranged between $10.7 million and $20.9 million during the fourth quarter of 2011 and between zero and $22.4 million during 2011. Fluctuations in the outstanding balance and related availability under our Credit Facility are driven primarily by cash flows from operations and the timing and nature of property and equipment additions that are not funded through notes payable, as well as the nature and timing of receipt of proceeds from disposals of property and equipment.

- Definition

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
