An articulated lorry, also known as a articulated truck or semi-trailer truck, is a large vehicle used for transporting goods. It consists of two main parts: a towing unit, called the tractor, and a separate trailer that carries the cargo. The connection between these two parts allows for greater flexibility and maneuverability, making it easier to navigate tight spaces. These vehicles are commonly used in the logistics and transportation industry due to their ability to carry heavy loads over long distances. Articulated lorries can be found on roads worldwide, playing a crucial role in the supply chain by delivering products to businesses and consumers.
