Switzerland’s Stick’AIR stickers – what you need to know

When air pollution levels rise, some parts of Geneva are closed to the most polluting vehicles. As a result, you’ll need to know what Stick’Air sticker you need, which parts of the city are affected, and what the potential penalties are.

We’ve gathered all the answers to make your Swiss road trip as stress-free as possible.

Stick’AIR stickers, or vignettes, are part of Geneva’s differentiated traffic scheme – a measure that was introduced in Switzerland in 2020, designed to improve air quality. 

During air pollution peaks, some vehicles are banned from driving through the centre of the city between the hours of 6am and 10pm. 

Coloured stickers are used to identify the polluting potential of a car and divide vehicles into six different emissions-based categories.

Passenger cars should display the following stickers:

Foreign cars must display the correct Stick’AIR vignette, including those registered in the UK.

If you already have a French Crit’Air sticker there’s no need to buy another – they are also recognised in the Geneva differentiated traffic zone.

The differentiated traffic zone covers most of the City of Geneva and the surrounding towns of Carouge, Cologny, Lancy and Vernier.

Look out for the below signs when entering the clean air zone

The differentiated traffic zone is enforced between 6am and 10pm, and the need for displaying a sticker only applies once recorded or forecast pollution levels reach a high level. 

No restrictions are enforced while pollution levels sit below the threshold limit.

• Clean Air Zones – what are they and where are they?
• Driving in Switzerland
• Swiss vignette

Stick’Air stickers or vignettes can be purchased for five Swiss Francs (just over £4) from the Office cantonal des véhicules and are valid for the life of the vehicle. 

Remember, if you already have a French Crit’Air sticker there’s no need to buy another – they are also recognised in the Geneva differentiated traffic zone.¹

A vehicle that doesn’t display a correct Stick’AIR vignette is prohibited to travel through the differentiated traffic zone during enforcement hours.

Drivers who travel in the zone without the correct sticker can be fined 500 Swiss Francs (roughly £400).

The differentiated traffic zone splits pollution levels into four categories:

• no pollution peak
• activation level
• alert level
• urgency level

These categories determine speed limits and bans on the types of vehicles that can enter the clean air zone.

• Low Emission Zones: what you need to know
• Temporary car insurance - from one hour to 30 days

Categorising the emissions of vehicles allows the Geneva authorities to regulate entry into the differentiated traffic zone dependant on pollution level.

The table below shows which cars can travel through the zone during varying pollution levels:

Public transport is free across all lines when pollution reaches the ‘alert level’.
