The term "eighteen-wheeler" refers to a type of heavy-duty vehicle commonly used in the transportation and shipping industry. It is typically a large truck or tractor-trailer combination that consists of a truck cab or tractor unit and a trailer with eighteen wheels in total. The name "eighteen-wheeler" is derived from the number of wheels on the entire vehicle, necessary to support the massive weight and cargo capacity it can carry.
These vehicles are commonly used for long-haul transportation of goods, as their size and capacity make them suitable for carrying large volumes of cargo over long distances. The truck cab, where the driver sits, connects to the trailer through a fifth wheel coupling. This connection allows the trailer to be securely attached to the tractor, providing stability and enabling the driver to control and maneuver the entire unit.
Due to the significant size and weight of eighteen-wheelers, they require specialized training and licensing for individuals to operate them. Drivers of these vehicles must possess commercial driver's licenses, along with extensive knowledge of safety protocols and regulations, to ensure safe navigation on highways and roads.

These vehicles have significantly transformed the industry by offering an effective means of cargo transportation, with their large capacity and ability to navigate long distances, making them an integral part of the modern logistics system.
