tractor-trailers

Highway freight haulers

Tractor-trailers are large commercial vehicles consisting of a cab (the tractor) pulling a detachable cargo container (the trailer).

The combination is also called a semi, semi-truck, eighteen-wheeler, or big rig.

The tractor provides the engine and driver's compartment; the trailer carries freight.

Tractor-trailers dominated the interstate.
