Light-duty towing and heavy-duty towing differ in the type of vehicles they can tow and the equipment used to tow them. Light-duty towing is designed for smaller vehicles up to 11k lbs., such as cars and small trucks, and typically involves using a flatbed or hook-and-chain tow truck. Heavy-duty towing is designed for larger vehicles above 10k lbs., such as buses, RVs, and tractor-trailers.
