A semi-trailer also know as a semi, tractoer-trailer, truck and trailer. It is an articulated vehicle consisting of a towing engine and a semi-trailer that carries the freight.

A semi-trailer doesn't trail completely behind the towing vehicle, but is attached at a point that is just forward of the rear-most axle of the towing unit, so that some fraction of the weight of the trailer is carried by the prime mover, with most of that at the rear axle and a small amount at the front. This arrangement requires both tractor and semi-trailer to be distinct in design from a rigid truck and trailer.
