A semi truck is a combination vehicle. It consists of a powered truck and one or more semi-trailers, and is also known as a tractor-trailer. Its tractor unit usually has two or three axles but may have up to five. Many are designed for commercial construction machinery, while some are made for passenger vehicles. A common tractor-cab layout includes a forward engine and one steering axle. Some trucks also feature a fifth-wheel trailer coupling, which allows the driver to adjust the weight distribution over the rear axles.
Although a semi truck is often referred to as a tractor-trailer, it also has many other names. For example, some people refer to it as a semi-tractor-trailer, while others refer to it as a big rig or an 18-wheeler. Whatever you call it, the name is a matter of semantics.
