TRAILER TRANSPORTATION

A trailer truck, also known as simply a semi-trailer truck, semi-tractor truck, semi-tractor-trailer or tractor-trailer truck, is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth-wheel. An TRAILER is a cargo where the length, breadth or height is more than the standard container dimension (20 ft, 40 ft, 50 ft,70 ft, high cube, Reefer).
It is variously known as a transport truck.
