France’s Crit’Air system regulates vehicle emissions in cities through low-emission zones (Zones à Faibles Émissions or ZFE). If you are driving into France from the UK or Germany, understanding how Crit’Air works is essential to avoid fines and entry restrictions.
What is Crit’Air?
Crit’Air is a colour-coded emissions sticker required for driving in many French cities. It applies to:
- Cars
- Vans
- Motorhomes
- Motorbikes
Both French and foreign-registered vehicles must comply. UK and German number plates are not exempt.
Where is Crit’Air required?
Crit’Air is mandatory in permanent low-emission zones in major cities including:
- Paris
- Lyon
- Marseille
- Toulouse
- Nice
- Strasbourg
- Montpellier
- Grenoble
- Rouen
Some cities also activate temporary restrictions during high pollution events.
How restrictions work
Each vehicle receives a category from 0 to 5 based on:
- Fuel type
- Euro emissions standard
- First registration date
Cities restrict access based on these categories. Having a sticker does not automatically guarantee entry if your category is banned.
What visitors must prepare
Before driving in France:
- Confirm your vehicle’s Crit’Air category
- Apply for your sticker in advance
- Allow time for delivery
- Display the sticker correctly on your windscreen
Fines can apply if you enter a ZFE without the correct category or without displaying a valid sticker.
