Many things can impact truck company behavior. Given that truck companies are generally profit-driven businesses, one of these things are operating costs. A report from the American Transportation Research Institute indicates that, recently, operating costs for truck companies have trended up here in the U.S.
The report estimated what the average marginal cost-per-mile was for truck operators in 2014. It estimated this average was $1.703 per mile. It based this estimate off of the results of a survey of truck companies. This estimate represents an increase over the estimated average truck company operating cost from 2013, which was $1.676 per mile.
