You must have a CDL to operate:

  • Any single vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or more.
  • A combination vehicle with a gross combination weight rating (GCWR) of 26,001 or more pounds, provided the GVWR of the vehicle(s) being towed is in excess of 10,000 pounds.
  • A vehicle designed to transport 16 or more passengers (including the driver).
  • Any size vehicle which requires hazardous material placards or is carrying material listed as a select agent or toxin in 42 CFR part 73.

Federal regulations through the Department of Homeland Security require a background check and fingerprinting for the Hazardous Materials endorsement. Contact your local department of driver licensing for more information.

This CDL manual is not a substitute for a truck driver training class or program. Formal training is the most reliable way to learn the many special skills required for safely driving a large commercial vehicle and becoming a professional driver in the trucking industry.
