There has been much confusion about who is required to have a U.S. Department of Transportation (USDOT) number. Many contractors feel it’s only needed for truckers hauling for hire, which is not the case.
A USDOT number is required for a commercial motor vehicle (
49 CFR Part 390.5), which is defined as any self-propelled or towed motor vehicle used on a highway in interstate and/or intrastate commerce:
- to transport passengers or property when the vehicle has a gross vehicle weight rating or gross combination weight rating, gross vehicle weight or gross combination weight, of 10,001 pounds or more, whichever is greater; or
- to transport more than eight passengers, including the driver, for compensation; or
- to transport more than 15 passengers, including the driver, without compensation; or
- to transport material found by the Secretary of Transportation to be hazardous under 49 USC 5103 and transported in a quantity requiring placarding under regulations prescribed by the Secretary under 49 CFR, subtitle B, chapter I, subchapter C.
The USDOT number serves as a unique identifier when collecting and monitoring a company’s safety information acquired during audits, compliance reviews, crash investigations, and inspections.
The following 31 states have laws agreeing to the enforcement of the federal USDOT regulations: Alabama, Alaska, Arizona, Colorado, Connecticut, Florida, Georgia, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Washington, West Virginia, Wisconsin, and Wyoming. The other states have state-based USDOT regulations (similar to federal OSHA vs. state OSHA regulations). Many think that the USDOT number does not apply here, but lack of enforcement does not equal “not applicable.” It is a federal regulation, and it applies to all subject commercial motor vehicles.
Vehicles that require USDOT numbers must have a name and USDOT number on both sides of the vehicle’s power unit, in a contrasting color, and visible from 50 feet away when parked. Currently, there is no cost to register for a USDOT number. You can visit

Up to you if want to get it. I find a DOT number is a real pain for doing the yearly report, biennial report, Heavy highway tax, weigh stations, insurance, GVW tax, CDL class A, and a medical every two years. I'm not a carrier with a bunch of 18 wheelers. Just a one man contractor. Amazing how an 85 year old can go buy a class A motorhome and tow a car behind and need nothing.
