A commercial motor vehicle is defined as any self-propelled or towed vehicle that:
A USDOT (United States Department of Transportation) Number is a carrier identification number assigned to a business or an individual operating in commerce.
A USDOT Number is required where any vehicle or combination of vehicle units are operated in intrastate or interstate commerce and meet the definition of a commercial motor vehicle (see above).
Whether your company operates intrastate only (solely within Colorado boundaries) or interstate commerce (traveling outside of Colorado), please continue to the FMCSA website and complete an application via their online system.
Interstate commercial motor carriers travel in states other than the one they are domiciled it and/or they cross state lines in the course of their business.
Intrastate carriers limit their operations to within the borders of one state.
The USDOT Number should appear on both sides of the commercial vehicle with the company name. The USDOT Number should be legible from 50 feet away in daylight hours. (most companies go with a minimum of 2″ lettering). For intrastate carries within Colorado only – If a power unit of a towing combination is less than 10,0001 lbs. and you are operating commercially within the State of Colorado only, you can put this information on both sides of the towed unit.
Carriers having USDOT#s are required to review and “update” their company information at least once every 24 months/2 years (biennially). Carriers should also update their carrier USDOT# information any time there are changes to the information they have provided in their application or recent update, like a change of address, point of contact, number of drivers/vehicles, etc.
Yes. All carriers having a USDOT# must file a biennial update every two years, regardless. Failure to do so could interfere with the good standing of your USDOT#.
