Brussels LEZ rules, foreign car registration, day pass and fines

The LEZ covers the 19 municipalities of the Brussels-Capital Region. The R0 ring road and some roads that lead to the transit car parks are not in it. Among these roads: chaussée de Waterloo between the regional boundary and drève Saint-Hubert, drève Saint-Hubert, drève du Haras between the regional boundary and drève Saint-Hubert, and the access to the ring road by the E411.

The sign marks the entrance and the exit. When you see the entrance sign, the car must meet the conditions. The check is automatic: 353 cameras, at the entrances, at the exits and inside the zone, read the plates.

A Euro 5 diesel and a Euro 2 petrol car no longer meet the conditions for driving in the LEZ. This applies to cars, vans, buses, trucks and motorcycles. The Constitutional Court ruling is dated 11 September 2025. The access rule itself has been in force since 1 January 2026.

A foreign plate registers, even if the car is allowed. Without registration, the fine is 150 €. False information at registration costs 25 €.

Even a foreign car that is compliant must be registered. Without registration, the fine is 150 €.

A car that does not meet the conditions may use a day pass, or an exemption if it has one. Without either, the fine is 350 €. Only one fine may be issued per vehicle every three months, and at most four times a year.

For vehicles covered since 1 January 2026, the first finding brings a warning letter. It informs you and gives you time to become compliant before the next entry. It does not allow you to continue with a banned car. If the car has not been made compliant with a day pass or an exemption, 350 € may be due from three months after the first finding.

From 1 July 2026, if the car is still not compliant, a fine can cover twelve months. The amount of 350 € is that of an annual pass the government intends to create. It is not a pass you buy today.

An official diversion, police or roadworks, that you followed is not an offence. If a fine arrives anyway, you can contest it. The route must be the diversion route. A camera that sees you somewhere else the same day, for example in the centre while the diversion was on the R0, prevents the cancellation.

The fine arrives through the LEZ process. Keep the letter: it tells you how to pay.
