May 2026 update: the Brussels Region has announced possible LEZ changes, but the official site still says the current legislation remains in force for the time being. The figures and rules below therefore reflect the official reference currently shown online.
Here is the simple version to keep in mind if your goal is to enter Brussels without a LEZ fine in 2026.
| Vehicle type | Standard to target in 2026 to enter without a fine | Simple reading |
|---|---|---|
| Diesel | >= Euro 6 | A Euro 5 diesel is no longer allowed |
| Petrol / LPG / CNG | >= Euro 3 | Euro 2 and lower are excluded |
| Electric / hydrogen | Allowed | Not affected by these thresholds |
For petrol motorcycles, the official logic is also at least Euro 3.

In practical terms, if your car is still a Euro 5 diesel, the answer to the question "can I drive it in Brussels in 2026?" is currently no.
The official fine currently displayed on LEZ.brussels remains €350 per infringement.
The official site also says that the same vehicle can receive only one fine every three months, with a maximum of 4 fines per year.
Since 1 January 2026, the newly excluded categories first receive a warning letter after their first infringement.
In practice, that means:
A simple example: if you enter with a Euro 5 diesel on 10 January 2026, you may first receive a warning. If you return with the same vehicle from 10 April 2026 onward without becoming compliant, the €350 fine may then apply.
Important: this transition rule does not apply to vehicles that had already been banned before 2026.

The Day Pass remains the simplest legal option if you need to drive into Brussels occasionally with a non-compliant vehicle.
That last point matters because some older pages still say the pass must always be bought before entry. For Brussels, the most reliable source remains the current FAQ on LEZ.brussels.
If you use the Day Pass regularly, the annual cost adds up quickly: 24 passes x €35 = €840.
The best reflex is to use the official vehicle checker on LEZ.brussels.
If you also want to check manually, look at your registration certificate:
If the vehicle does not yet have a plate or if the Euro standard is unclear, the official site also allows a manual check.
Yes. The LEZ covers all 19 municipalities of the Brussels-Capital Region.
Two practical nuances matter:
For drivers, that means a P+R + public transport strategy still makes sense if the vehicle itself is no longer allowed into the Region.
Because the political debate around the Brussels LEZ moved a lot in 2026. Several announcements mentioned a lower fine or an annual pass.
But if you need the most useful answer today, the key point is this: LEZ.brussels still says the current legislation remains in force for the time being.
So the official practical reference remains:
If you are still driving legally with Euro 6 or using a Day Pass occasionally, fuel remains the other real cost.
With Seety, you can:
Seety does not change LEZ rules, but it does help reduce the total cost of trips into Brussels.

No. Under the official regime currently displayed on LEZ.brussels, a Euro 5 diesel is not allowed in Brussels' LEZ in May 2026. The safe diesel threshold is now Euro 6.
Yes. In practice, Euro 6 minimum remains the safe diesel threshold to enter Brussels' LEZ without a fine.
The Day Pass costs €35 per day, with a maximum of 24 passes per year and per vehicle. It remains valid until 6 a.m. the next morning.
Yes. Foreign vehicles are also covered by the Brussels LEZ. The official site adds that a foreign vehicle must be registered, even when it already meets the technical standards.
Because other policy scenarios were announced in 2026. But as long as LEZ.brussels says the current legislation still applies, that official regime remains the most reliable practical reference for drivers.
