An articulated truck is a truck that combines a tractor and a trailer and connects them with a pivoting bar. Typically, the trailer is loaded with goods and pulled by a tractor unit. Since trailers are less maneuverable than regular vehicles, they are typically utilized for long-distance freight transportation. And heavy or exceptionally bulky items are frequently transported using the tractor unit. 

The most typical application for an articulated truck is in the construction industry. These vehicles, which can be categorized as a sort of tractor-trailer unit, are used to transport huge goods, sometimes through challenging terrain. There are straightforward ones for carrying cargo as well as articulated dump trucks with loaders. 

An articulated truck's drive system is its key distinguishing characteristic that places it in a different driving category. The number of wheels on the axles being used to pull the truck determines the driving system. The most popular system is the 6 x 6 system, which uses all six of the truck's wheels while it is being driven.
