An articulated lorry is a lorry with the combination of a tractor and a trailer which are connected by a pivoted bar. Usually, goods are loaded on the trailer, and the tractor unit is used to pull it.
The trailer is not as agile as normal trucks, so they are mainly used in long-distance freight transport. And the tractor unit is often used to transport particularly bulky or heavy goods. There are various types of articulated lorry such as buses, trams and trains.
This is the type of vehicle with a permanent or semi-permanent pivot joint.
