Several hundred European cities now restrict older, more polluting vehicles with low emission zones (LEZs). Some need a windscreen sticker, some need you to register online, and some just read your number plate. Get it wrong and the fine can run to a few hundred euros, often arriving at home weeks later.
This guide covers how the zones work in each country, which stickers to order and how long they take, how to check your car's Euro standard, the fines, and what to do if your car doesn't qualify.
What Are Low Emission Zones?
A Low Emission Zone is a defined area, usually in a city centre, where vehicles that exceed certain pollution thresholds are either banned outright or charged a fee to enter. The goal is to reduce harmful nitrogen dioxide (NO2) and particulate matter (PM) emissions in densely populated areas.
LEZs go by different names depending on the country:
- ULEZ (Ultra Low Emission Zone) in the United Kingdom
- ZFE (Zone a Faibles Emissions) in France
- Umweltzone in Germany
- ZTL Ambiente in parts of Italy
- Miljozone in Denmark and Sweden
While the names differ, the principle is the same: your vehicle must meet a minimum emissions standard, typically based on its Euro emission class, to enter legally.
Which Countries and Cities Have LEZs?
There are several hundred zones across Europe and the number changes every year. These are the ones you're most likely to meet on a road trip.
United Kingdom
London's ULEZ now covers the entire Greater London area. Vehicles that do not meet Euro 4 (petrol) or Euro 6 (diesel) standards pay a daily charge of £12.50. The Clean Air Zones in Birmingham and Bristol charge non-compliant cars; Bath's doesn't charge private cars. Glasgow, Edinburgh, Aberdeen and Dundee have LEZs that ban non-compliant vehicles, with a penalty rather than a charge. There's no sticker: cameras read your number plate, and foreign-registered vehicles should be registered with TfL before driving in London.
France
Paris, Lyon, Marseille, Strasbourg, Toulouse, and many other French cities operate ZFE zones that require a Crit'Air vignette. This colour-coded sticker (ranging from green for electric vehicles to grey for the most polluting) must be displayed on your windscreen. Order it only from the official site (certificat-air.gouv.fr), where it costs a few euros; delivery to the UK can take weeks. In the Greater Paris zone, Crit'Air 3 and above are restricted on weekdays. French ZFE rules have been politically contested and some cities have softened them, so check each city before you go.
Germany
Berlin, Munich, Cologne, Stuttgart and dozens of other German cities require a green Umweltplakette (environmental sticker). Several cities have scrapped their zones in recent years, but the sticker is still needed in many. Diesels need Euro 4 or better for the green sticker; petrol cars need Euro 1 with a catalytic converter. Without it, the fine is 100 euros. The sticker costs around 5-15 euros and can be purchased at TUV stations, vehicle registration offices, or online.
Belgium
Brussels, Antwerp, and Ghent all have LEZs. There is no sticker system; instead, you must register your vehicle online before entering. Diesel vehicles below Euro 5 and petrol vehicles below Euro 2 are banned in Brussels. Fines start at 150 euros and can reach 350 euros for repeat offenders.
The Netherlands
Amsterdam, Utrecht and several other Dutch cities restrict older diesel cars and vans (Rotterdam dropped its zone for cars in 2020). Many Dutch cities also have zero-emission zones for delivery vans and lorries. Enforcement is by number plate camera; check milieuzones.nl for each city.
Italy
Italian cities have some of the most confusing restricted zones in Europe, combining traffic-limited zones (ZTL) with emission-based restrictions. Milan's Area B bans diesels up to Euro 5 and older petrol cars on weekdays. Rome, Florence, Bologna, and Turin also have emission restrictions that vary by season and pollution levels.
Scandinavia
Copenhagen, Aarhus, Aalborg and Odense have camera-enforced zones that now cover older diesel cars as well as lorries; foreign vehicles may need registering online. Stockholm and Gothenburg mainly target heavy vehicles, with a stricter car zone on parts of central Stockholm. Oslo uses toll charges that vary by fuel type and time of day.

Stickers and Vignettes: What You Need and How to Get Them
Some countries require physical stickers on your windscreen, while others use automatic number plate recognition. Here is a quick reference for the main sticker systems.
Stickers You May Need
- France (Crit'Air): Order from certificat-air.gouv.fr. Cost: a few euros. Delivery to the UK: allow several weeks. Valid for the life of the vehicle.
- Germany (Umweltplakette): Purchase at TUV/DEKRA stations, online retailers, or some ADAC offices. Cost: 5-15 euros. Valid indefinitely.
Registration-Based Systems (No Sticker)
- United Kingdom: Register your vehicle via TfL's online checker before entering London's ULEZ.
- Belgium: Register online at lez.brussels, lez.antwerpen.be, or stad.gent/lez.
- Netherlands: Automatic number plate recognition; check milieuzones.nl for eligibility.
- Denmark: Camera-based since 2022; foreign vehicles may need registering online.
If you need both a French Crit'Air and a German Umweltplakette, order them at least six weeks before your trip. Postal delays are common.
How to Check If Your Vehicle Is Compliant
Your vehicle's eligibility depends on its Euro emission standard, which is determined by its date of first registration and fuel type. Here is a simplified guide:
- Euro 6 (diesel) / Euro 4 (petrol): You will pass virtually every LEZ in Europe. This covers most vehicles registered after September 2015 (diesel) or January 2006 (petrol).
- Euro 5 (diesel): Compliant in most zones now but increasingly being phased out. Check individual cities.
- Euro 4 (diesel) or older: Likely restricted in most major city LEZs.
You can find your vehicle's Euro standard on your V5C registration document (UK), the Certificate of Conformity, or by checking with your national vehicle registry.
What About Campervans and Motorhomes?
Campervans and motorhomes are subject to the same LEZ rules as other vehicles in their weight class. Older diesel motorhomes are particularly at risk of being non-compliant. Some cities classify motorhomes over 3.5 tonnes as heavy goods vehicles, which face stricter restrictions. Check the specific rules for each city, as a vehicle that is fine in one zone may be banned in another.
Fines and Enforcement
Fines vary a lot, and not knowing the rules isn't a defence. Typical penalties:
- France: 68 euros for cars, 135 euros for trucks and buses.
- Germany: 100 euros.
- Belgium: 150-350 euros depending on the city and whether it is a repeat offence.
- United Kingdom: £12.50 daily charge for ULEZ; £180 penalty for non-payment (reduced to £90 if paid within 14 days). Clean Air Zones that charge cars, such as Birmingham's, charge around £8-9 a day.
- Italy: Variable, but typically 80-335 euros depending on the zone and municipality.
- Netherlands: Around 100 euros or more for cars, higher for commercial vehicles.
Enforcement is increasingly automated. Cities use ANPR cameras that read number plates and cross-reference them against registration databases. Some fines are sent to your home address weeks later, and cross-border fine collection within the EU has become much more effective in recent years.
Workarounds and Alternatives
If your vehicle does not meet the requirements, you still have options.
Park and Ride
Many cities with LEZs have park-and-ride sites on the outskirts (see our guide to parking in European cities). Leave your car outside the zone and take public transport into the centre. Cities like Paris and London have extensive metro networks that make this easy.
Rent a Compliant Vehicle
If city driving is a significant part of your trip, consider renting a newer vehicle that meets all emission standards. Most rental cars from major companies are Euro 6 compliant. Some agencies now offer electric vehicle options that bypass all LEZs entirely.
Plan Your Route Around LEZs
If you are simply passing through a region, you may be able to route around the LEZ entirely. Some navigation apps and sat navs now flag emission zones and can route around them, but don't rely on them alone.
Temporary Day Passes
A few cities offer temporary exemptions or day passes for visiting vehicles. Check individual city websites, as these are not universally available and often need to be arranged in advance.
If you are renting a car for a European road trip, ask the rental company to confirm which emission stickers are already fitted. Some companies pre-install Crit'Air and Umweltplakette stickers; others leave it to you.
Planning Your Trip Around LEZs
Check the zones along your route before you leave home, alongside any vignettes and tolls you'll need.
For a comprehensive road trip through Western Europe, you may need stickers or registrations for multiple countries. Build this into your preparation timeline at least four to six weeks before departure.
Use Plan Your Road Trip to map out your route and identify which LEZs you will encounter along the way.
Frequently asked questions
Can I drive through a Low Emission Zone if I am just passing through and not stopping?
In most cases, yes, you are still subject to the restrictions even if you are just driving through. The rules apply to all vehicles within the zone boundaries regardless of whether you stop. Some cities have designated transit routes that bypass the restricted area, so check your specific route carefully.
Do electric vehicles and hybrids get free access to all LEZs?
Fully electric vehicles meet LEZ rules everywhere, though you still need a sticker where one is required (Crit'Air 0 in France, the green sticker in Germany). Plug-in hybrids usually get a top rating (such as Crit'Air 1 in France or a green sticker in Germany) and are allowed in nearly all zones at present. However, some cities are considering future restrictions on hybrids as they push towards zero-emission goals, so check the latest rules for your destination.
