What it means
A USDOT number identifies a motor carrier to FMCSA for safety oversight, inspections, audits and crash data. In general it is required for vehicles operating in interstate commerce above FMCSA's weight thresholds, and carriers display it on their trucks.
Why it matters for your business
Shippers and brokers look up a carrier's USDOT record before booking freight. A trucking website that shows the USDOT number clearly, with authority and insurance details, removes doubt and speeds up the first load.
