Choosing the correct Crit’Air category is essential to avoid application errors and fines.
What determines your category?
Your category depends on:
- Euro emissions standard
- Fuel type
- First registration date
Diesel vehicles often receive higher category numbers than petrol equivalents.
Common mistakes
- Guessing the category based on age alone
- Confusing petrol and diesel Euro standards
- Assuming UK or German registration affects classification
Why accuracy matters
Incorrect category selection can:
- Invalidate your sticker
- Prevent entry into ZFE zones
- Result in penalties
If unsure, consult official emissions documentation or apply through a guided service.
