A tow bar is a device attached to the rear of a vehicle, designed to pull trailers or other vehicles. It typically consists of a strong metal frame and a hitch that connects to the trailer's coupling. Tow bars are commonly used for towing caravans, boats, or other trailers, making them essential for transporting goods or recreational equipment. Tow bars come in various types, including fixed, detachable, and swan neck designs, each suited for different towing needs. Proper installation and adherence to weight limits are crucial for safety. Many vehicles, including SUVs and trucks, are equipped with tow bars for added versatility.
