Visitors to the UK can usually use a vehicle displaying foreign number plates for six months. This can be made up of a single visit or several shorter visits in a 12-month period, provided all taxes, including vehicle tax, are paid in the country of origin.
If a vehicle with foreign plates is stopped by the police, it's the responsibility of the keeper to show that they are allowed to use the vehicle in the UK without registering and taxing it.
Drivers of vehicles from outside the EU need to show HM Revenue and Customs (HMRC) that they are allowed to use the vehicle in the UK on a temporary basis. If they are, a HMRC Notice 3 is issued, which is stamped with the date the vehicle should leave the country.
The decision lies with HMRC whether a visiting vehicle from outside the EU can be granted visitor status. HMRC will decide whether an extension to the six month period can be granted, if not they will issue status certificates (forms C&E 386 or C&E 388). The vehicle must then be registered at a Driver and Vehicle Licensing Agency (DVLA) local office.
It is the responsibility for the driver to prove how long the vehicle has been in the country. This can be done by producing ferry tickets.
EU vehicles brought into the UK will be allowed to be used freely for six months in any 12-month period without the need to register in the UK, provided the vehicle complies with the requirements of its home country. Where the keeper of the vehicle becomes resident in this country, the vehicle must be immediately registered and licensed in the UK. UK residents are not allowed to use a foreign registered vehicle on UK roads.
Certain vehicles will be required to display a temporary 'Q' plate. Temporary visitor status isn't appropriate to these vehicles.
