At the beginning of 2017, the French government brought in a new scheme to categorise vehicles according to how polluting they are to the environment using a system of colour-coded stickers.
The scheme now operates in more than 27 environmental zones across France, including Paris, Grenoble, Lyon and Rennes.
Foreign vehicles must adhere to the scheme so, if you plan to travel in these cities, you will need to order the correct sticker for your vehicle in advance.
You will find more information about the scheme and how to get a sticker for your vehicle at www.crit-air.fr/en.html
