South Carolina issues licenses as proof that you've been examined and are qualified to operate a particular type of vehicle. The class license you will need is based on the gross vehicle weight rating (GVWR) or gross vehicle weight (GVW).
Commercial Licenses
• Class A : Any combination of vehicles with a GCWR of 26,001 or more pounds provided the GVWR of the vehicle(s) being towed is in excess of 10,000 pounds.
• Class B : Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing a vehicle not in excess of 10,000 pounds GVWR.
