Towing capacity refers to the maximum weight that a vehicle, such as a truck or SUV, can safely pull behind it. This limit is determined by the vehicle's design, engine power, and braking system. Exceeding this capacity can lead to safety hazards, including loss of control and increased wear on the vehicle. Manufacturers provide towing capacity ratings in the owner's manual or on the vehicle's specifications label. It's important to consider the weight of the trailer and any cargo it carries, as well as the weight of passengers and gear in the vehicle itself, to ensure safe towing practices.
