Just received my cit'air sticker for my 2009 Fiat Ducato 130 Multyjet. It's an Orange Cit'air 3 certificate. I'm waiting to receive the one for my car now. Not that I intend going to Paris in the Motor Home, But a few weeks ago Grenoble adopted the same scheme. I have been looking to find out what the color code is for the day to be able to enter either Paris, Lyon or Grenoble; This is the only thing I could find which might be of some help to others on here.https://www.crit-air.fr/en.html Then scroll down to "You find here the daily news about the Crit’Air vignettes allowed to drive for: Paris, Lyon, Grenoble"
