	NOTE 4. Fair Value Measurement
	The carrying value of cash and cash equivalents, accounts receivable and accounts payable and long term debt approximated fair value as of June 30, 2014 and December 31, 2013.
	We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of June 30, 2014 and December 31, 2013, our cash and temporary investments were with high quality financial institutions in Demand Deposit Accounts.
	Restricted investments included $22.0 million and $20.8 million as of June 30, 2014 and December 31, 2013, 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 6. 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 through 2020.
	The potential maximum exposure under these lease guarantees was approximately $34.4 million and $39.0 million as of June 30, 2014 and December 31, 2013, respectively. The potential maximum exposure represents the amount of the remaining lease payments on all outstanding guaranteed leases as of June 30, 2014 and December 31, 2013. 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 quarter ended June 30, 2014 or the year ended December 31, 2013 and no potential material defaults.
	We had a liability of approximately $0.5 million as of June 30, 2014 and $0.7 million as of December 31, 2013, for the guarantees representing the fair value 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.

The purchases totaling approximately $7.8 million will occur as the leases expire throughout 2014. As of June 30, 2014, we have purchased approximately 1,750 containers with the remaining 250 containers, for approximately $0.9 million, to be purchased in the second half of the year.
	In March 2014, we entered into an equipment purchase contract for the acquisition of 300 Freightliner tractors. The total purchase price of these tractors is approximately $39.3 million. We expect to take delivery of the equipment between July and December 2014.
	In April 2014, we entered into equipment purchase contracts for the acquisition of up to 4,000 containers. We have decided to acquire 3,500 new 53’ containers at a total cost of $38.3 million. We expect to take delivery of the equipment between June and November 2014. As of June 30, 2014, we have received 418 containers.
	We intend to finance the purchase of the new containers and tractors with secured fixed rate debt.

Legal Matters	'
	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, and 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 materially 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., now known as Hub Group Trucking, Inc. Mr. Robles drove a truck for Hub Group Trucking 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 Hub Group Trucking who were classified as independent contractors, from January 2009 to the present. The complaint alleges Hub Group Trucking 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 Hub Group Trucking 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 district court stayed proceedings in the case pending decisions by the Court of Appeals for the 9th Circuit to decide whether the claims in two cases raising some similar claims should be dismissed on federal preemption grounds. In July 2014, the Court of Appeals ruled that the claims in those cases were not preempted. The parties have notified the district court of the 9th Circuit’s decisions and the case will now proceed. 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). This Standard provides guidance on how to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For public organizations, the guidance in the Update is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The update provides two transition methods to the new guidance: a retrospective approach and a modified retrospective approach. Early application is not permitted. We plan to adopt this standard January 1, 2017, as required. We are currently evaluating the effect this update will have on our consolidated financial statements.
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued an update to Topic 360 – Property, Plant and Equipment and Topic 205 – Presentation of Financial Statements: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The amendments in the update change the requirements for reporting discontinued operations in Subtopic 25-20. The guidance is effective for annual reporting periods beginning after December 15, 2014, including interim reporting periods within that reporting period and is to be applied prospectively. We plan to adopt this standard January 1, 2015, as required. We do not expect this new guidance to have a significant impact on our consolidated financial statements.
