Fair Value Measurement	'
	NOTE 4. Fair Value Measurement
	The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximated fair value as of September 30, 2013 and December 31, 2012 due to their short-term nature.
	We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of September 30, 2013 and December 31, 2012, our cash is with high quality financial institutions in DDAs (Demand Deposit Accounts).
	Restricted investments included $19.1 million and $17.2 million as of September 30, 2013 and December 31, 2012, respectively, of mutual funds which are reported at fair value.
	The fair value measurement of these securities is based on quoted prices in active markets for identical assets which are defined as “Level 1” of the fair value hierarchy in the Fair Value Measurements and Disclosures Topic of the Codification.

Guarantees [Abstract]	'
Guarantees	'
	NOTE 5. Guarantees
	As a recruiting tool for our owner-operators, we are guaranteeing certain owner-operators’ lease payments for tractors. The guarantees expire at various dates beginning in 2013 through 2020.
	The potential maximum exposure under these lease guarantees was approximately $42.2 million and $48.2 million as of September 30, 2013 and December 31, 2012, respectively. The potential maximum exposure represents the amount of the remaining lease payments on all outstanding guaranteed leases as of September 30, 2013 and December 31, 2012. However, upon default, we have the option to purchase the tractors. We could then sell the tractors and use the proceeds to recover all or a portion of the amounts paid under the guarantees. Alternatively, we can contract with another owner-operator who would assume the lease. There were no material defaults during the periods ended September 30, 2013 and December 31, 2012 and no potential material defaults.
	We had a liability of approximately $0.8 million as of September 30, 2013 and $1.0 million as of December 31, 2012, representing the fair value for estimated defaults of the guarantees, based on a discounted cash-flow analysis which is included in current and non-current liabilities in our Consolidated Balance Sheets. We are amortizing the amounts over the remaining lives of the respective guarantees.

	NOTE 6. Commitments and Contingencies
	During the first half of 2013, we entered into equipment purchase contracts for the acquisition of 4,029 53’ containers. We expect the total cost of purchasing the containers to be approximately $45.7 million. As of September 30, 2013, $11.3 million of the remaining $25.8 million to be paid is accrued in our current liabilities. As of October 14, 2013, 3,258 containers have been delivered with the remaining 771 containers to be delivered by the end of 2013.
	During the fourth quarter of 2012, we exercised our purchase option on approximately 4,000 containers that are currently leased. In addition, during the second quarter of 2013, we exercised our purchase option on another 200 containers that are currently leased. The purchases, totaling approximately $14.8 million, will occur as the leases expire throughout 2013. As of October 14, 2013, we have purchased 3,193 containers for approximately $11.4 million.

	NOTE 8. Legal Matters
	We are a party to litigation incident to our business, including claims for personal injury and/or property damage, bankruptcy preference claims, claims regarding freight lost or damaged in transit, improperly shipped or improperly billed. Some of the lawsuits to which we are party are covered by insurance and are being defended by our insurance carriers. Some of the lawsuits are not covered by insurance and we defend those ourselves. We do not believe that the outcome of this litigation will have a material adverse effect on our financial position or results of operations.
	On January 25, 2013, a complaint was filed in the U.S. District Court for the Eastern District of California (Sacramento Division) by Salvador Robles against our subsidiary, Comtrak Logistics, Inc. Mr. Robles drove a truck for Comtrak in California, first as an independent contractor and then as an employee. The action seeks class certification on behalf of a class comprised of present and former California-based truck drivers for Comtrak who were classified as independent contractors, from January 2009 to the present. The complaint alleges Comtrak has misclassified such drivers as independent contractors and that such drivers were employees. The complaint asserts various violations of the California Labor Code and claims that Comtrak has engaged in unfair competition practices. The complaint seeks, among other things, declaratory and injunctive relief, compensatory damages and attorney’s fees. In May 2013, the complaint was amended to add similar claims based on Mr. Robles’ status as an employed company driver. These additional claims are only on behalf of Mr. Robles and not a proposed class. In August 2013, the court stayed proceedings in the case pending decisions by the Court of Appeals for the 9th Circuit to decide whether two similar cases should be dismissed on federal preemption grounds. We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from this lawsuit.

New Pronouncements	'
	NOTE 9. New Pronouncements
	In July 2012, the FASB issued an update to Topic 350 – Intangibles – Goodwill and Other of the Accounting Standards Codification. The objective of this update is to simplify how entities test indefinite lived intangibles for impairment. The amendments in the update permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of the indefinite lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative test described in Topic 350. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. We adopted this guidance effective January 1, 2013 as required, and the adoption did not impact our consolidated financial statements.
