Liquidity Disclosure1 [Text Block] | 2. LIQUIDITY Our business requires significant capital investments over the short-term and the long-term. We generally finance 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 proceeds from the sale of our used revenue equipment in 2017 and 2016. We had working capital (total current assets less total current liabilities) of $81.1 million and $47.9 million at December 31, 2017 and 2016, respectively. 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. As of December 31, 2017 , we had $9.0 million of borrowings outstanding , undrawn letters of credit outstanding of approximately $32.9 million, and available borrowing capacity of $53.1 million under the Credit Facility. 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 collection of accounts receivable, payments of accrued expenses, and receipt of proceeds from disposals of property and equipment.

- Definition Disclosure 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. + References No definition available. + Details
