In order to drive a truck, you must have a Commercial Driver's License (CDL). A CDL is a specialized driver’s license proving knowledge of the vehicle's operation.
There are three types of CDLs available: CDL Class A, B, and C.
CDL Class A: This license allows operation of most types of trucks, single or combined with a gross vehicle weight rating (GVWR) of 26,001 pounds or more with a towing weight of 10,000 pounds or more. It includes all license classes.
CDL Class B: Operators are licensed for single or combined vehicles with a GVWR of 26,001, but towed loads must be under 10,000 pounds. Class B licensees can also operate class C vehicles.
CDL Class C: This license allows operation of a vehicle carrying a total of 16 passengers, including the driver, only if it is under 26,001 GVWR. It also allows carrying of hazardous material if it’s under the 26,001 threshold. Class A and B are not allowed.
