Tractor-trailer

A tractor-trailer, also known as a semi-truck or big rig, is a large vehicle used for transporting goods over long distances. It consists of two main parts: the tractor, which is the front section containing the engine and driver’s cabin, and the trailer, which is the connected cargo container that carries freight. The tractor pulls the trailer via a hitch, allowing for easy attachment and detachment. This combination is essential for efficient freight movement, enabling the transportation of goods across highways while allowing for flexible loading and unloading at different destinations.
