What is the main function of a road tractor?

The main function of a road tractor is to draw another vehicle without carrying cargo itself. This is particularly significant in the context of commercial transportation, where road tractors are typically used to pull trailers that may contain various types of freight. The design of a road tractor enables it to efficiently handle the mechanical demands of towing, as it is equipped with features such as a powerful engine and a hitch system tailored specifically for this purpose.

In commercial trucking, road tractors play a vital role in logistics and freight movement, allowing for flexibility in transporting goods. They are not intended to carry loads directly, as that responsibility falls on the trailer or the towed vehicle. This distinction is essential in understanding the operational dynamics of road tractors within the broader transportation and logistics frameworks.
