There are three CDL classes which permit drivers to operate a wide range of vehicles, and Class C drivers can drive large vans, small trucks, and combination vehicles, such as a small truck with a trailer in tow. The Class C license allows drivers to transport 16 passengers, cargo, or hazardous materials (HAZMAT). Class A drivers can operate tractor-trailers, flatbeds, tankers, and livestock carriers. Class B drivers can drive large buses, box trucks, and dump trucks.
