We're planning a circle tour through Alsace and a few locations in Germany, flying in and out of Frankfurt, where we'll rent and return a car. I considered trains, but the cost and logistics just don't work.
France now has a requirement in certain areas that your vehicle must have an environmental sticker on in it. Strasbourg is one of those areas. You can only apply for the sticker online and it is mailed to you. You must have all the registration info for the car in order to apply.
Obviously this isn't possible when you're renting a vehicle. Online sources seem to say that French rental cars will have the sticker, but we're renting in Germany.
I've reached out to the rental car company and am awaiting an answer, but I thought I'd see if anyone here has any insight. If we can't get this resolved, we may have to stay elsewhere and train into Strasbourg for the couple of days we want to tour there. Very frustrating!
