Whether you can enter the low-emission zone depends on the Euro emissions standard and fuel of the vehicle.
- The Euro emissions standard is a European environmental standard for vehicles and is represented by a number. The higher the euro emissions standard, the lower the emissions. For trucks and buses, the euro emissions standard is indicated by a Roman numeral.
- Fuel: the conditions for entry are stricter for diesel cars. These emit more soot and particulate matter.
Your vehicle's euro emissions standard or class can be found on the registration certificate in the 'environmental class' section.Can't find a euro emissions standard there? Then the date of first registration of your vehicle determines whether it can enter the LEZ or not.
Foreign vehicle? The following is an overview of all registration certificates in Europe.
You must always register a foreign vehicle before entering the LEZ.
The Flemish Government recently decided not to tighten the LEZ. Diesel vehicles with Euro 5 standard and petrol vehicles with Euro 2 standard will continue to have access to the LEZ. The Flemish Government will evaluate air quality in 2027 and decide whether or not to tighten the regulations.
