An articulated lorry is a large commercial transport vehicle consisting of two separate components: a powered tractor unit (cab or prime mover) and a detachable semi-trailer, connected by a pivot joint mechanism known as the fifth wheel coupling. This articulation point allows the two sections to move independently at an angle, providing enhanced maneuverability compared to rigid vehicles of equivalent length.
