There are international agreements which provide for the temporary use of a vehicle in a foreign country for a limited time, usually 6 months in a 12 month period. It is the responsibility of the driver to prove how long the vehicle has been in the country. A visitor to the U.K. may use a vehicle displaying foreign plates, provided that all taxes (including vehicle excise duty) are paid in their country of origin. Once a vehicle has been registered in the U.K. it must display a current Vehicle Excise Licence and if over three years old be submitted for a Ministry of Transport Test.
