Touring demands urgent clarity on Brussels LEZ fines after rule changes and court ruling
Updated 14 June 2026, 12:00 UTC. BRUSSELS, 4 June 2026: motorists’ organisation Touring has asked Brussels authorities for urgent clarifications on Low Emission Zone fines, La DH reported, after the region’s LEZ calendar was restored by the Constitutional Court and the first penalties for newly excluded vehicles entered the enforcement window. The official LEZ.brussels portal states that diesel Euro 5 and petrol Euro 2 vehicles, along with some petrol motorcycles below Euro 3, can no longer circulate in the Brussels Region from 1 January 2026. Drivers newly affected receive a warning after a first offence, and a €350 fine can follow no earlier than three months later if the same vehicle breaches the rules again.
The issue matters directly to drivers, commuters and small businesses using older vehicles in Brussels. LEZ.brussels states that fines for non-compliant vehicles are €350, with a maximum of one fine every three months per vehicle. Clear rules determine whether drivers adapt, buy a day pass, request a derogation, change vehicle or contest a penalty.
The subject is Brussels’ Low Emission Zone, a regional traffic and air-quality system covering the 19 Brussels municipalities. The immediate actor is Touring, the mobility organisation that La DH says réclame clarifications urgentes on how amendes LEZ à Bruxelles are being applied. The institutional actors are Brussels Mobility, Brussels Fiscality, Brussels Environment and the Constitutional Court.
Background
Brussels introduced the LEZ on 1 January 2018 to reduce road-traffic pollution. The Brussels Environment 2024 evaluation says the measure helped cut road-traffic NOx emissions by 55% between 2018 and the end of 2024 at constant mileage. The Constitutional Court suspended the March 2025 ordinance that had allowed some vehicles to continue accessing the LEZ until 31 December 2026.
Impact
Regional — The impact is concentrated in the Brussels-Capital Region because the LEZ covers all 19 municipalities, according to LEZ.brussels. Flemish and Walloon commuters entering Brussels are also affected when their vehicles fall under the restricted Euro categories.
Opposing perspectives
- Touring and affected motorists
Touring, according to La DH, wants Brussels authorities to clarify how LEZ fines are being applied. The affected constituency includes drivers who received warnings, commuters using older diesel vehicles and businesses that need predictable enforcement before they enter the capital.
- Brussels air-quality and health advocates
Environmental and public-health organisations that challenged the delay argued before the Constitutional Court that postponing the LEZ milestone weakened protection for health and the environment. The Court treated the constitutional health and environmental argument as serious at the suspension stage.
- Brussels regional administration
The official LEZ.brussels portal presents the current law as still in force while noting announced adaptations linked to the formation of a new Brussels government. Its published rules keep the warning period, the €350 fine and existing day-pass and derogation routes in place.
