This is what we do here Now I would like to go spontaneously over Easter a few days to Berlin. We will live in the Isarstrasse, and that is apparently exactly within the environmental zone. What do I do now without the badge? My car apparently only gets the yellow badge – and then I can probably Don’t know me so well… We just want to go there, leave the car for the days and then return to DK again, so don’t bend through the city with it. Should I sneak to the apartment in the dark in the evening? And bring some money for the punishment? What does the loss cost today? Or should I leave it at bahn.de and look at greetings from DK!
