A Department of Transportation (DOT) number is a number that the Federal MotorCarrier Safety Administration, or FMCSA assigns to registered commercial vehicles.
Companies that operate commercial vehicles which haul cargo, weigh more than a certain amount, or transport passengers in interstate commerce must be registered with the FMCSA and must have a USDOT Number. In most U.S. states, local DOT requirements also apply.
This number is used for collecting and monitoring a company's safety information which is acquired during audits, compliance reviews, crash investigations, and inspections.
To list or rent most vehicles on COOP, your business must have an active US Department of Transportation number. If you need to apply for a DOT number, read here for more information.
