For what I believe is the first time driving in and around Geneva is restricting today due to the ozone level:
Mesures pour lutter contre la pollution à l’ozone
Pic de pollution à l’ozone
L’ozone est un gaz agressif nocif pour la santé.
- Seuls les véhicules motorisés avec le macaron Stick’AIR 0, 1, 2 et 3 seront autorisés à circuler au centre du canton de Genève entre 6h et 22h.
- La vitesse est limitée à 80 km/h sur le contournement genevois.
- les transports publics sont gratuits.
- La mesure est reconduite ou étendue selon l’évolution de la situation.
Measures to combat ozone pollution
Ozone pollution peaks
Ozone is an aggressive gas that is harmful to health.
Only motor vehicles with a Stick’AIR 0, 1, 2 or 3 sticker will be allowed to drive in the centre of the canton of Geneva between 6 a.m. and 10 p.m.
The speed limit is 80 km/h on the Geneva ring road (A1 Motorway including to/from the airport)
Public transport is free of charge.
The measure will be renewed or extended depending on how the situation develops.
Edited to add:
• Stick’AIR 0: For electric or hydrogen vehicles.
• Stick’AIR 1: For Euro 5 and 6 standard petrol vehicles, and most Euro 6 diesels.
• Stick’AIR 2: For Euro 4 petrol, Euro 5 and 6 diesels.
• Stick’AIR 3: For Euro 2 and 3 petrol, Euro 4 diesels.
2nd edit. Driving without a Stick”AIR attached to your windshield/screen is prohibited in the restricted area.
Third edit:
The restricted area for Geneva’s Stick’AIR scheme covers nearly all of the City of Geneva and several adjacent municipalities, specifically:
- Geneva proper (Ville de Genève)
- Carouge
- Cologny
- Lancy
- Vernier
This differentiated traffic zone is enforced during high air pollution periods, typically from 06:00 to 22:00, and only allows motorized vehicles with authorized Stick’AIR stickers (categories 0, 1, 2, or 3) to circulate. The restricted area is clearly marked by signs on main access roads and can temporarily expand based on air quality needs[2][3][10].
If you already have a French Crit’Air sticker, it is also valid in these zones. Vehicles without a valid sticker, or those with prohibited categories, are not permitted to circulate in the restricted area during enforcement times[3][2].
Public transport often becomes free within the affected area (zone 10 Unireso) during these periods to encourage compliance and reduce car traffic[3][10].
