Advice for driving in Germany With regard to your answer to correspondent AH of Sheffield, who was planning to drive to Germany, they need to know that a great many urban areas have been designated environmental zones (Umweltzonen). To drive in these areas, which include all major cities, you are required to display a sticker (Umweltplakette) in your windscreen. Failure to do so could result in a fine. Stickers are available at the nearest TÜV station to the border and cost about €10 (£8). Any modern car should qualify for a green sticker (number four) that allows travel anywhere. Many readers might not know that, so that's a very useful reminder.
