Got the acknowledgement of my sticker today. Interested what people do if they are travelling around Europe. Don't understand why the EU hasn't got this sorted & you can get one sticker to cover all the different countries, looking at this web page Badges/Vignettes in Europe – Crit-Air.fr I count 6 different stickers that you might need, don't know about London as its probably the last place on earth I would want to drive to. Then what about all the different parking stickers, different clubs etc. where would I put my Wildcamping sticker. Probably get done for obscuring the view.
