Is a petrol Euro 3 admitted to the Brussels LEZ today?

Yes. Euro 3 is the current petrol minimum across all 19 communes, so this car meets it exactly - with no margin. Euro 2 petrol and Euro 5 diesel were the classes removed on 1 January 2026.

When does that change?

On 1 January 2028, when the official agenda refuses petrol Euro 3 and diesel Euro 6b, 6c and 6d-TEMP, lifting the petrol minimum to Euro 4. After that this car is non-compliant rather than borderline.

What are the options once it is refused?

Day passes at EUR 35, capped at 24 per vehicle per year, which is the region's own mechanism for vehicles that cannot meet the standard. Beyond that cap there is no route in for a non-compliant car.

Does registration still matter for a car that qualifies?

Very much. It is free, valid five years, and can be done before entering or within five days of entering. A compliant foreign car that was never registered is fined EUR 150, against EUR 350 for a car that fails the standard itself.

Why is confirming the exact class worth the trouble here?

Because there is nothing in reserve. One class lower is EUR 350 rather than a warning, so the Euro number should be read from field V.9 of the registration document or the certificate of conformity rather than inferred from the car's age.

Brussels 2026: Petrol Euro 3 Is In Until January 2028

Checked against official sources 20 Sep 2026 · Next review 2026-12-19

Petrol Euro 3 is the exact floor of the Brussels LEZ, so this car is admitted — and it is the class the region has already scheduled for removal. From 1 January 2028 petrol Euro 3 is refused and the minimum becomes Euro 4. Until then: register the plate free, and treat EUR 350 as the price of being one class out rather than a theoretical risk.

Can your car enter Brussels?

Enter your vehicle's fuel + Euro class → instant verdict for Brussels (LEZ). Fine if wrong: EUR 350 (non-compliant vehicle); EUR 150 (foreign vehicle not registered, even if compliant); EUR 25 (incorrect registration data). Warning letter for the first offence..

The 2026 line came from a Constitutional Court ruling in September 2025, which removed Euro 2 petrol and Euro 5 diesel. The 2028 line is already on the official agenda alongside the refusal of diesel Euro 6b, 6c and 6d-TEMP. Neither is a rumour to monitor; both are dates to plan around.

Zero margin changes what you should check

A car two or three classes above a floor can be assumed compliant. A car sitting on the floor cannot. Read the Euro class from field V.9 of the registration document or the certificate of conformity before the trip, because the difference between Euro 3 and Euro 2 here is the difference between free entry and EUR 350.

After the step, the day pass is the mechanism

The region sells day passes at EUR 35, capped at 24 a year per vehicle, for vehicles that cannot meet the standard. That is what this car’s 2028 position looks like in practice: not a locked city, but a metered one with an annual ceiling. It is worth knowing now if the same car is expected to return.

The paperwork does not wait for 2028

Registration at lez.brussels is free, valid for five years, and allowed before entering or within five days of entering. Vehicles registered in the Netherlands are read automatically; every other foreign plate must be entered. A compliant but unregistered foreign car is fined EUR 150, and incorrect registration details cost EUR 25. A first offence brings a warning letter, with the fine following around three months later.

Brussels checklist for this car

✅ Confirm Euro 3 specifically — there is no margin beneath it
✅ Register the plate free before departure, or within five days of entering
✅ Plan any 2028 return around the new Euro 4 petrol floor
✅ Price the fallback honestly: EUR 35 a day, maximum 24 days a year
✅ Remember EUR 350 is the standard failure and EUR 150 the missing registration
