The U.S Postal Service contracts with suppliers that operate highway contract routes (HCR) to transport mail and equipment between plants, post offices, or other designated points that receive or dispatch mail. HCRs made up the largest single group of transportation services used by the Postal Service in fiscal year (FY) 2022. The Postal Service has increased its emphasis on improving trailer utilization of HCRs and Postal Vehicle Services by developing strategies to eliminate underutilized trips and reduce transportation costs.
