A Class C license is a state-issued form of identification that authorizes drivers to commercially operate heavy vehicles that are carrying hazardous materials or more than 15 passengers.

Although the exact specifications of a Class C license vary from state to state, it typically allows drivers to operate vehicles with a Gross Vehicle Weight Rating of 26,000 pounds or more, while transporting 15 or more people or hazardous waste. A Class C license is also needed for towing vehicles under 10,000 pounds. Depending on which state issues it, a Class C license may be referred to by alternative titles, such as Group C, Group B, Commercial License or CDL.
