A Commercial Driver’s License (CDL) allows someone to operate certain commercial motor vehicles, depending on the CDL Classification. There are three main types of CDLs:

• Class A – Able to operate any combination of vehicles with a GCWR of 26,001 lbs. or more to include a towed vehicle heavier than 10,000 lbs. Class A vehicles include tractor-trailers, truck and trailer combinations, and flatbeds.
• Class B – Able to operate a single vehicle with a GVWR of 26,001 lbs. or heavier and/or any vehicle that is towing another vehicle up to 10,000 lbs. Some examples of Class B vehicles are straight trucks and large buses.
• Class C – Able to operate a vehicle that does not meet the criteria of either a Class A or Class B license and is meant to transport at least 16 passengers or HAZMAT with the proper endorsements. Class C vehicles are usually small HAZMAT vehicles or passenger vans or buses.
