ROAD TRAFFIC

Under regulation 16 of the Road Vehicles (Display of Registration Marks) Regulations 2001 the international distinguishing sign of the United Kingdom may be displayed in the format stipulated in Council Regulation (EC) No 2411/98 (Official Journal L299, 10.11.98, p1) to the left of a registration plate attached to a vehicle registered in the UK. This format includes a representation of the flag of the European Union. Annex 4 of the Geneva Convention on Road Traffic of 1949 specifies that the letters “GB” are the distinctive letters for purposes of international traffic of vehicles registered in the United Kingdom.
