The LEZ in Brussels: a cleaner air for everyone!

Brussels is a LEZ (Low Emission Zone). The most polluting vehicles are banned from driving there in order to protect the health of Brussels residents.

NEWS

The two-year postponement of the Low Emission Zone (LEZ) in the Brussels Region was suspended by a ruling of the Constitutional Court on Thursday 11 September 2025. The Court ruled that the postponement violated the right to health and a healthy environment. The initial LEZ timetable has therefore been reinstated with immediate effect.

EURO 5 diesel and EURO 2 petrol vehicles (cars, vans, buses, lorries), as well as petrol motorcycles that do not meet at least the Euro 3 standard, are therefore no longer allowed to circulate in the Brussels Region.

However, to allow owners of these vehicles to comply, a transitional period has been put in place:

From 1 January 2026, motorists who are in breach of the regulations will first receive a warning letter.
They will then have three months to comply: the first fine of 350€ will only be issued three months after the first offence.

Examples:

If you drive in the LEZ with a Euro 5 diesel vehicle on 1 January 2026, you will first receive a warning letter. If you drive the same vehicle again from 1 April 2026 onwards, you may receive a 350€ fine.
If you drive in the LEZ with a Euro 5 diesel vehicle on 15 June 2026, you will first receive a warning. If you use this vehicle again from 15 September 2026 onwards, you may receive a fine of 350€.

How can you avoid a fine?

From mid-November, the lez.brussels website will be updated to reflect these changes. You will be able to:

Check whether your vehicle is concerned using the simulator
Purchase a day pass (max. 24 passes/year)
Consult all possible exemptions
Check the LEZ map and locate the Park & Ride (P+R) car parks located at the entrances to Brussels, where you can leave your vehicle and use public transport

There are subsidies available!

Get rid of your vehicle and receive the Bruxell'Air subsidy or the subsidy for professionals (only for Brussels residents)

Who?

Which vehicles are affected?

The access criteria for driving in the LEZ depend on the vehicle’s category, fuel type, and Euro standard.

Currently, in order to drive in the LEZ without receiving a fine, diesel vehicles (cars, vans, buses, lorries) must comply with at least Euro 6 standard. Petrol, CNG and LPG vehicles (cars, vans, buses, lorries and motorcycles) must comply with at least Euro 3 standard.
