An 18-wheeler, or tractor-trailer, consists of several key parts: the tractor, which is the front part that contains the engine and driver's cab, and the trailer, which is the rear compartment used for hauling cargo. The tractor is connected to the trailer via a fifth wheel coupling, and the entire vehicle typically has 18 wheels—10 on the tractor and 8 on the trailer. Other essential components include the chassis, axles, and various systems for braking and cargo securing.

In the case of an 18 wheeler, air lines will connect from the tractor to the trailer to operate the trailer's air brake system.
