What is a Truck Tractor?

Truck tractors, also known as semi-trucks or simply tractors, are heavy-duty trucks designed for towing trailers. They have a powerful engine, a large cabin for the driver and sometimes a passenger, and a fifth wheel coupling to connect to the trailer. Truck tractors are commonly used in the transportation industry for long-distance hauling of goods and materials. They are often seen on highways and interstates pulling a variety of trailers, such as dry vans, flatbeds, and refrigerated trailers.
