Towing capacity refers to the maximum weight that a vehicle, such as a truck or SUV, can safely pull behind it. This weight includes the trailer and any cargo loaded onto it. Towing capacity is determined by the vehicle's design, engine power, and braking system, ensuring safe and efficient towing. To find a vehicle's towing capacity, you can check the owner's manual or look for a label on the driver's side door frame. It's important to stay within this limit to avoid damaging the vehicle and to ensure safe driving conditions while towing a trailer or other loads.
