Imports from non-member EU states are restricted by age. Personal vehicles are restricted to 8 years (from date of first registration to date of customs declaration), and vehicles intended to be used for business are restricted to 5 years. Vehicles imported from non-member states which are not approved for European roads have to pass import inspection, and modified to meet restrictions. For vehicles from the U.S. or Canada it is mandatory to change headlights, or adjust them for the EU bulb pattern, change red rear turn signals to orange ones, separate them from brake wiring, and add fog lights. Importing cars with RHD has been allowed from 20 May 2018, but the headlights and fog lights have to be converted to the continental pattern.
