Why is an articulated lorry called that?

The term "articulated lorry" refers to a specific type of large commercial vehicle consisting of two or more sections connected by a flexible joint, otherwise known as an articulation joint. The front section, known as the tractor or towing vehicle, houses the engine, driver's cabin, and controls for operating the vehicle. The rear section, known as the trailer, carries the load or cargo.

The term "articulated" in this context specifically refers to the jointed connection between the tractor and the trailer. This allows the vehicle to maneuver more easily, especially when turning or navigating tight spaces. The articulation joint allows the trailer to pivot independently from the tractor, providing increased flexibility and maneuverability compared to a rigid vehicle.

The advantages of articulated lorries include:

- Increased maneuverability: The articulation joint allows for greater flexibility in navigating tight spaces and making sharp turns.

- Improved weight distribution: The separation of the engine and cargo into separate sections helps distribute weight more evenly, enhancing stability and handling.

- Increased cargo capacity: Articulated lorries can accommodate larger cargo loads compared to rigid trucks due to the flexibility of the connection between the tractor and the trailer.
