Types of trucks and their use
There are mainly two types of trucks straight and articulated. If all the axles are attached to a single frame, it is called a straight truck. And if a truck has two or more frames which are connected by couplings, it is called an articulated truck. A full trailer is designed in a way so that its own weight and its load is upon its wheels. On the other hand, a truck tractor is designed to carry its own weight and a part of a load of the semitrailer. Semitrailer has one or more axles and designed in a way so that a part of its weight and load rest upon a truck.
About half of the revenues collected by government agencies from federal and state highway users in the US are from the trucking industry. There are rules and regulations for length, height, weight, safety standards, speed, etc. Which are almost similar to the rules and regulations for passenger cars.
