Other Trucking Industry Terminology
Accessorial Charges
Fees for services beyond standard pickup and delivery (e.g., detention, layover, driver assist, liftgate, residential delivery, tarping). Often itemized on invoices and governed by carrier tariffs or contracts.
Examples: 1) “Our base rate excludes accessorials like detention and liftgate.” 2) “Add a tarping accessorial to the flatbed quote.”
Adverse Driving Conditions Exception

Examples: 1) “We invoked the adverse conditions exception due to unexpected black ice.” 2) “Dispatch noted the snow squall so the driver could extend drive time by two hours.”
Backhaul
A return trip from destination back toward the origin market. Often priced lower than headhaul because capacity is seeking freight to reposition.
Examples: 1) “We priced that lane as a backhaul so the rate is lower.” 2) “Finding a backhaul reduces empty miles after the headhaul.”
Bill of Lading (BOL)
