Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 10. Commitments and Contingencies From time-to-time, we are a party to routine litigation arising in the ordinary course of business, most of which involves claims for personal injury and property damage incurred in connection with the transportation of freight. We maintain insurance to cover liabilities arising from the transportation of freight for amounts in excess of certain self-insured retentions. In management's opinion, our potential exposure under pending legal proceedings is adequately provided for in the accompanying condensed consolidated financial statements. On August 26, 2014, the U.S. District Court for the Southern District of Ohio issued a pre-trial decision in a lawsuit against our Southern Refrigerated Transport, Inc. subsidiary (“SRT”) relating to a cargo claim incurred in 2008. The court awarded the plaintiff approximately $5.9 million plus prejudgment interest and costs and denied a cross-motion for summary judgment by SRT. Previously, the court had ruled in favor of SRT on all but one count before overturning its earlier decision and ruling in favor of the plaintiff. SRT filed a Notice of Appeal with the U.S. Sixth Circuit Court of Appeals on September 24, 2014 and that appeal has been fully briefed by the parties and oral arguments will be scheduled in the coming months. As a result of this decision and pending final outcome of the appeal, we increased the reserve for this claim by approximately $7.5 million to approximately $8.1 million during the third quarter of 2014. We had $37.0 million and $34.3 million of outstanding and undrawn letters of credit as of March 31, 2015 and December 31, 2014, respectively. The letters of credit are maintained primarily to support our insurance programs. Effective April 2015, we entered into a new auto liability policy with a three-year term. The policy retains the first $1.0 million per occurrence limit for the primary layer of our auto liability program and expands excess coverage to $75.0 million. Additionally, effective April 2015, we commuted two liability policies for the period from April 1, 2013 through September 30, 2014, such that we are now responsible for any claim that occurred during that period up to $20.0 million, should such a claim develop. As a result of the commutation and the Company's improved safety statistics over the prior policy, the Company received favorable premium pricing for the upcoming three year policy period, which should reduce the fixed portion of insurance expense going forward.
