What Are Vehicle DOT Numbers?

A United States Department of Transportation, or USDOT, number is used primarily on commercial-based vehicles as a unique identifier that helps in monitoring the companies safety information during audits or inspections. Individuals only need a DOT number when their vehicle matches a specific criteria.

Individuals are required to have a USDOT number if their vehicle has a gross weight rating, or vehicle weight or gross combination rating of more than 10,000 pounds; is designed to transport at least eight passengers, including the driver, for compensation; is designed to transport at least 15 passengers, including the driver, without compensation; or is used in transporting hazardous material in a quantity that requires placarding.
