Fleet R&M expenses averaged 16.7 cents per mile and $6.58 per hour in 2017 , according to the 2018 Operational Costs of Trucking report by the American Transportation Research Institute (ATRI). The report shows R&M costs increased by more than 60 percent from 2008 to 2017 on a per-mile basis, despite the average miles driven per truck declining 13.6 percent during this period. ATRI attributes R&M increases to technology advancements in newer power units and trailer models. While equipment continues to be more expensive to repair and maintain, the bridges are a path to savings by aligning the resources of all departments to maximize the impact of maintenance outcomes and by spreading these successes across the entire organization.
