A commercial driver license, commonly known as a CDL, is required to operate certain types of motor vehicles. There are 3 types of commercial driver licenses – Class A, Class B, and Class C,

Class A – The Class A commercial driver license permits the holder to operate any combination of vehicles with a gross combination weight rating of 26,001 pounds or more, provided the gross vehicle weight rating (GVWR) of the vehicle or vehicles towed exceeds 10,000 pounds.

Class B – The Class B commercial driver license permits the holder to operate any single vehicle with a GVWR of 26,001 pounds or more, any one of those vehicles towing a vehicle that does not exceed 10,000 pounds GVWR, and any vehicle designed to transport 24 passengers or more, including the driver. If the skills test is taken in a bus with a GVWR of less than 26,001 pounds, the holder will be restricted to operating busses under 26,001 pounds GVWR.

Class C – The Class C commercial driver license permits the holder to operate any single vehicle or combination of vehicles that is not a Class A or B if the vehicle is designed to transport 16 to 23 passengers including the driver, or used in the transportation of hazardous materials that require the vehicle to be placarded under 49 CFR, Part 172, Subpart F.
