A semi-trailer is a trailer whose axles are placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device (king pin) that can transmit horizontal and vertical forces to the tractor. Part of the total load of the trailer is borne by the tractor.

Features: without power in itself, it carries the goods with the tractor, and driven by the tractor.
