Brussels' Tighter 2026 LEZ Still Lets a 2010 Petrol In
Brussels raised its LEZ petrol floor to Euro 3 on 1 January 2026 following a court ruling, and a 2010 petrol Euro 4 still clears the new line. LEZ registration remains free; entering unregistered risks EUR 150-350.
Can your car enter Brussels?
Enter your vehicle's fuel + Euro class → instant verdict for Brussels (LEZ). Fine if wrong: EUR 150-350.
Can a petrol Euro 4 car enter Brussels?
Yes. Brussels raised its LEZ petrol floor to Euro 3 on 1 January 2026, following a Constitutional Court ruling the previous September, and this 2010 petrol Euro 4 clears the new line by a full class. Meeting the emission standard isn’t the whole story, though — Brussels still requires every vehicle, compliant or not, to register its plate with the LEZ system before entering.
Registration at lez.brussels is free and can be completed online ahead of your trip. Skipping that step — even in a fully compliant car — risks the same EUR 150-350 fine that applies to non-compliant vehicles, since the system checks registration status by ANPR, not just Euro class.
What you still need to do
- Register your plate at lez.brussels before you drive in — it costs nothing but takes a few minutes.
- Confirm your Euro class from the vehicle’s Certificate of Conformity rather than assuming from the registration year.
- Keep proof of registration accessible in case of a roadside check.
If registration lapses or you’re unsure
- Register before you travel. It’s free and avoids any risk entirely.
- Park & Ride outside the LEZ boundary is the fallback if you’d rather not deal with registration on a short visit.
- Check lez.brussels directly if your plate or vehicle details have changed since a prior registration.
How Brussels’s LEZ is enforced
The zone has operated since 2018 and is monitored by ANPR cameras around the clock, checking both Euro-class compliance and registration status. Because registration and compliance are checked together, a compliant but unregistered car is treated the same as a non-compliant one at the camera.
Quick compliance checklist for Brussels
- ✅ Confirm your Euro class from the CoC — Euro 4 clears the current Euro 3 petrol floor
- ✅ Register the plate at lez.brussels regardless of compliance — it’s free but mandatory
- ✅ Keep registration confirmation with the vehicle
- ✅ The zone runs 24/7, so there’s no unmonitored window
- ✅ Budget for the EUR 150-350 fine only if registration is skipped
