CDL Vehicle Groups and Endorsements


CDL laws divide commercial vehicles into three groups:

Group A- A combination of vehicles with a total mass of 26,001 or more pounds and gross towing weight of more than 10,000 pounds

Group B- A single commercial vehicle with a mass of 26,001 or more pounds and a gross towing weight of 10,000 pounds or less

Group C- A smaller vehicle or combination of vehicles that does not meet Group A or B classifications. Group C vehicles can either be a passenger vehicle designed to carry 16 or more people (including the driver), or they can used to transport hazardous materials.

Endorsements are “add on” authorizations you may need depending on which type of vehicle you would like to drive. For example, if you would like to drive a truck that transports hazardous materials, you would need a Class C license with a Hazardous Materials (H) endorsement. Below are some of the common CDL endorsements:

A= Combination Vehicles

B= Heavy Straight Vehicles

C= Small Vehicles

H= Hazardous Materials

N= Tank Vehicles

P= Passenger

S= School Bus

T= Double and Triple Trailers

X= Tank vehicle with Hazardous materials
