Income Tax Disclosure [Abstract]
Income Taxes	Con-way's first-quarter effective tax rate in 2013 was 16.5%, compared to the first-quarter 2012 effective tax rate of 38.1%. Significant variations in the customary relationship between income tax expense and pretax income are largely due to discrete adjustments. The 2013 tax rate was impacted by a $3.4 million benefit for discrete adjustments, mainly the result of a $3.3 million benefit for the alternative-fuel tax credits for 2012 that were recognized in the first quarter of 2013 because of a retroactive change to tax laws. The 2012 tax rate reflects a $0.2 million benefit for discrete adjustments. Other accounts receivable in the consolidated balance sheets include income tax receivables of $11.7 million and $6.6 million at March 31, 2013 and December 31, 2012, respectively.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
