Ah Paris – the city of light, love – and the Crit'Air pollution sticker. From March 31, in order to enjoy the French capital's many delights by car during weekdays, you will need to obtain a Crit'Air pollution sticker for your car.

What is a Crit'Air pollution sticker?

Crit'Air is a new system which categorises cars in terms of how polluting they are. There are six sticker types, ranging from the green sticker for zero-emission electric cars, up to the grey/blue '5' sticker for the most polluting vehicles. From March 31st you will need to have one of these stickers on your car in order to drive in Paris between 8am and 8pm, Monday to Friday.

How can I get a Crit'Air pollution sticker?

Owners of non-French vehicles can buy an anti-pollution sticker on the official site for 4.80 euros, including postage.

Beware of numerous websites selling stickers for inflated fees. Some of these are charging almost 30 euros - more than six times the official price.

What if I am driving around Paris en-route to the south?

The ‘boulevard périphérique’ – the ring road that marks out Paris proper – can be used without a sticker. Many UK drivers take this route when heading to southern parts of France. But if you venture inside this road, you will need a sticker. Be careful when using your sat-nav – they have been known to direct motorists into the 18km tunnel beneath the city; such a detour would also require a sticker.

How do I know if I am about to enter a Crit'Air zone?

The red sign below means you are entering the Crit'Air zone; the black one appears when you leave it.

What are the penalties for not having a sticker?

French police have been told to be lenient in the early days of the system, but the official fines are €68 (£58.63) for cars and €138 (£119) for lorries. The mayor of Paris, Anne Hidalgo, is clear she wants to improve the poor air quality of the capital – so police are likely to strictly enforce the rules in the coming months.

Police will enforce the system manually, in contrast to London's Congestion Charge, which uses cameras to monitor vehicles.

Are any vehicles not permitted in the city?

If your car was registered before 1996 you won’t be given a sticker, because your car won’t be allowed in the city at all between 8am-8pm, Monday to Friday.
