Testing & Licensing Requirements

Drivers who want to operate a commercial motor vehicle (e.g., truck or commercial bus) must first obtain a Commercial Driver's License (CDL), which falls under at least one of the following three commercial groups:

  • Combination Vehicle (Group A): Any combination of vehicles with a gross combination weight rating (GCWR, or sum of the weights of the vehicle and all units the vehicle is towing)* of 26,001 pounds or more, provided the gross vehicle weight rating (GVWR, which is the value specified by the manufacturer as the loaded weight of a single vehicle) of the vehicle(s) being towed is in excess of 10,000 pounds. 
  • Heavy Straight Vehicle (Group B): Any single vehicle with a GVWR of 26,001 pounds or more, or any such vehicle towing a vehicle not in excess of 10,000 pounds GVWR. 
  • Small Vehicle (Group C): Any single vehicle, or combination of vehicles, that meets neither the definition of Group A nor that of Group B, but that either is designed to transport 16 or more passengers including the driver, or is used in the transportation of hazardous materials.

*Note: Gross combination weight rating (GCWR) is the greater of:

  • A value specified by the manufacturer of the power unit, if such value is displayed on the Federal Motor Vehicle Safety Standard (FMVSS) certification label required by the National Highway Traffic Safety Administration; or
  • The sum of the gross vehicle weight ratings (GVWRs) or the gross vehicle weights (GVWs) of the power unit and the towed unit(s), or any combination thereof, that produces the highest value. Exception: The GCWR of the power unit will not be used to define a commercial motor vehicle when the power unit is not towing another vehicle.
