In Germany all vehicles which want drive into the LEZs must buy a sticker. This sticker must be put in the windscreen, which is then valid for all LEZs in Germany. Stickers [Plakette in German] can be bought from garages, testing stations [TÜV], the LEZ city administration, or online, for example from TÜV-Nord in several languages.
In the Netherlands, Dutch vehicles are registered through the national database and foreign vehicles are not enforced.
