A hitch is a device used to connect a trailer or other load to a vehicle, allowing for safe transportation. Hitches come in various types, including receiver hitches, fifth-wheel hitches, and gooseneck hitches, each designed for specific towing needs. They are typically mounted to the rear of a vehicle and can support different weight capacities. Proper installation and use of a hitch are crucial for safety. It is important to match the hitch type and weight rating with the trailer being towed. Additionally, using safety chains and ensuring the load is balanced can help prevent accidents during transport.
