A semi-trailer is a trailer without a front axle. In the United States, the term is also used to refer to the combination of a truck and a semi-trailer; a tractor-trailer,
A large proportion of a semi-trailer’s weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly, or the tail of another trailer. The other portion of the semi-trailer’s weight is semi-supported (half-supported) by its own wheels, which only support the rear of the semi-trailer.A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors.[7] Semi-trailers are more popular for transport than full trailers, which have both front and rear axles. Ease of backing is cited as one of the semi’s chief advantages. A road tractor coupled to a semi-trailer is often called a semi-trailer truck or “semi” in North America & Australia, and an articulated lorry or “artic” in the UK.
