DVLA is required to record vehicle details for road safety and law enforcement. The body type information held on the vehicle record must describe what a vehicle looks like in traffic. This description, as well as other distinguishing features, allows the police and other enforcement agencies to easily identify vehicles.
The body type does not affect the insurance category of the vehicle, or have any effect on speed limits or other legislative requirements. It is only used for establishing vehicle appearance and identification.
It is important to remember that even if the vehicle’s body type is not changed to ‘motor caravan’, the vehicle can still be used for this purpose as long as the keeper is satisfied the converted vehicle meets the required internal features for motor caravans.
