If you wish to anonymously report a vehicle that appears to be unlicensed and used/kept on the public highway you may submit the details electronically using this form.

The information provided can then be used for further investigations. However, the vehicle must be parked in the reported location on a regular basis so that an Agency Inquiry Officer will be able to make a sighting of the vehicle and then complete a formal witness statement.
