If you are planning a road trip through Europe, there is one thing that can catch you off guard faster than a speed camera: Low Emission Zones (LEZs). Hundreds of cities across Europe now restrict older, more polluting vehicles from entering certain areas, and the rules vary wildly from country to country. Drive into one without the right sticker or registration, and you could be facing fines of several hundred euros.
This guide covers everything you need to know about LEZs across Europe in 2025, from the stickers you need to the cities you should watch out for, plus practical workarounds if your vehicle does not meet the requirements.
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?
As of 2025, over 320 Low Emission Zones are active across Europe. Here is a breakdown of the major ones road trippers are most likely to encounter.
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, Bristol, and Bath also charge non-compliant vehicles. There is no sticker system; cameras automatically read your number plate, so you must register your foreign vehicle in advance via the TfL website.
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. You can order one online for about four euros, but delivery can take weeks, so plan ahead. Vehicles rated Crit'Air 4 or worse are typically banned during weekday hours in Paris.
Germany
Berlin, Munich, Cologne, Stuttgart, and over 50 other German cities require a green Umweltplakette (environmental sticker). Only vehicles meeting Euro 4 or better receive the green sticker. Without it, you face fines of 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, Rotterdam, Utrecht, and other Dutch cities restrict older diesel vehicles (typically pre-Euro 4 trucks and pre-Euro 3 passenger diesels). Many Dutch cities are moving towards zero-emission zones for delivery vehicles by 2025. Registration is automatic via number plate recognition.
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 restricts Euro 0-3 diesel vehicles. Rome, Florence, Bologna, and Turin also have emission restrictions that vary by season and pollution levels.
Scandinavia
Stockholm, Gothenburg, and Copenhagen have LEZs primarily targeting heavy vehicles, though passenger vehicle restrictions are expanding. Oslo has taken a different approach with congestion charging that varies by emission class and time of day.
Pro tip: The website urbanaccessregulations.eu is the most comprehensive, up-to-date database of every LEZ in Europe. Bookmark it before your trip and check each city on your route.
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: ~4.61 euros. Delivery: 10-30 days. Valid indefinitely once issued.
- Germany (Umweltplakette): Purchase at TUV/DEKRA stations, online retailers, or some ADAC offices. Cost: 5-15 euros. Valid indefinitely.
- Austria (Pickerl for NOx): Some Austrian cities require an emissions badge. Available at OAMTC offices. Cost: ~5 euros.
- Denmark (EcoSticker): Required for heavy vehicles entering Copenhagen, Aarhus, Aalborg, and Odense. Order from the Danish Environmental Protection Agency.
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.
Pro tip: 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, and driving without them is not worth the risk.
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
LEZ fines vary significantly across Europe, and ignorance of the rules is not accepted as a defence. Here are some 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; £160 penalty for non-payment (reduced to £80 if paid within 14 days). Clean Air Zones charge £8-50 daily.
- Italy: Variable, but typically 80-335 euros depending on the zone and municipality.
- Netherlands: Up to 250 euros for passenger vehicles, more 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 offer excellent park-and-ride facilities on the outskirts. 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. Many GPS navigation apps now include LEZ data and can suggest alternative routes. Waze and TomTom both flag emission zones in their routing.
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.
Pro tip: 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
The best approach is to research the zones along your planned route before you leave home. Use our trip planner to map out your journey and check which cities you will be passing through.
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 are exempt from LEZ restrictions across all European cities. Plug-in hybrids generally receive the highest emission rating (such as Crit'Air 1 in France or a green sticker in Germany) and are currently allowed in all zones. However, some cities are considering future restrictions on hybrids as they push towards zero-emission goals, so check the latest rules for your destination.
What if my vehicle is registered outside of Europe?
Non-European vehicles are subject to the same rules. You will need to register your vehicle or obtain the relevant stickers just like any European driver. For sticker-based systems, you typically need to provide your vehicle registration document and may need to get an emissions test. Contact the relevant national authority well in advance, as processing times for non-EU vehicles can be longer.
