A commercial motor vehicle (CMV), is defined in Colorado Revised Statute 42-4-235 as: "any self-propelled or towed vehicle bearing an apportioned plate or having a manufacturer's gross vehicle rating (GVWR) or gross combination rating (GCWR) of ten thousand one pounds or more, which vehicle is used in commerce on the public highways of this state..."

Colorado Revised Statute 42-4-235 requires motor carriers to be knowledgeable of the safety regulations for commercial motor vehicles.

Small truck and combination vehicle (vehicles with a GVWR or GCWR, between 16,001 and 26,000 pounds) drivers are not exempt from complying with the safety requirement contained in the Federal Motor Carrier Regulations (FMCSR) as adopted by the State of Colorado.
