Large commercial trucks are generally in two parts. The cabin is where the truck driver operates the vehicle. This is the cockpit of the truck with the steering wheel and brakes. The second part is the trailer bed, or the part of the truck for the cargo. Some trucks have two trailer beds for extra cargo. Some states even allow triple trailers. The trailers are connected to the cabin and the other trailers by a hitch. This hitch is what keeps them connected. However, defects in the hitch, improper maintenance, and improperly hitching the trucks can result in tractor trailer unhitch accidents in New Mexico.
