Semi-trailer
From Wikipedia, the free encyclopedia
(Redirected from Semi trailer)
A semi-trailer is a trailer without a front axle. A large proportion of its weight is supported either by a road tractor or by a detachable front axle assembly known as a dolly. A semi-trailer is normally equipped with legs which can be lowered to support it when it is uncoupled.
A road tractor pulling a semi-trailer is also called a semi-trailer truck.
