A semi-truck, also known as a semi-trailer truck, tractor-trailer, or big rig, is a large commercial vehicle used for hauling long distances. It consists of a tractor unit and one or more trailers that can be attached to it. The tractor unit typically has four wheels and is powered by an internal combustion engine. The trailer usually has two axles and is usually pulled by the tractor.

Semi-trucks are used to transport goods over long distances and are essential for the global supply chain. They can carry a wide variety of cargo, including groceries, building materials, electronics, and industrial chemicals. Semi-trucks can also be used for transporting livestock or hazardous materials such as hazardous waste or explosives.

Semi-trucks come in many shapes and sizes. They range from light-duty trucks with two axles to heavy-duty trucks with six axles or more.

The size of the semi-truck depends on the weight of the cargo it’s carrying. In addition to different sizes, semi-trucks also come in different configurations such as flatbeds, refrigerated trailers, tanker trailers, and dump trucks.

Driving a semi-truck requires special skills and knowledge due to its size and weight. Drivers must be properly trained in order to operate these vehicles safely on public roads and highways. Driving laws for semi-trucks are different from those for other motor vehicles because of their size and weight.
