An articulated vehicle is a heavy goods vehicle, 'bendy' bus or tram which is towing a semi-trailer, so constructed that a significant part of its weight is borne by the tractor.
The term 'trailer' includes drawbar trailers, which have at least two axles and the front axle is steered by the drawbar connecting it to the towing vehicle. It also includes towed equipment such as mobile compressors, heavy plant, and circus equipment
A caravan means a two-wheeled or four-wheeled trailer designed for accommodation, including mobile offices.
A single trailer is any combination consisting of a rigid vehicle and any trailer other than a caravan connected by a rigid bar. A double/multiple trailer is any combination including two or more trailers.
Other tow includes vehicles towing by rope and breakdown trucks towing another vehicle by crane-mounted tow, but specifically excludes drawbar trailers.
