What is the Difference Between a Semi-Truck and a Truck?

You likely have heard many different names used for the giant vehicles that haul goods and cargo on the highway – semi-truck, tractor-trailer, big rig, 18-wheeler, or simply truck. But do each of these names refer to different types of vehicles? Are there any differences between a truck, semi-truck, and 18-wheeler?
Semi-Truck, Truck, 18-Wheeler: What’s the Difference?

Depending on the context, the term “truck” may refer to a wide range of commercial vehicles, including box trucks, tractor-trailers, semi-trucks and 18-wheelers in Utah. These specific terms typically refer to a truck’s body type, wheels, and other defining characteristics.

A semi-truck has two parts: a trailer, which carries cargo, and a tractor, which contains the engine. Notably, a semi-truck’s tractor can detach from its trailer, and semi-trucks often travel without trailers.

The terms 18-wheeler and tractor-trailer simply refer to a semi-truck and its trailer. Tractor-trailers are sometimes called 18-wheelers due to the total number of wheels on the tractor and trailer.

Are All Semi-Trucks Commercial Motor Vehicles?
