One vignette covers the whole year — there's no short-stay option. Headlights stay on everywhere, and there are no low-emission zones to plan around.
Even a single afternoon on the motorway costs the full CHF 40; there's no day or week rate.
Buy near the end of the year and it already covers most of the next one too.
The fine doesn't replace the purchase — you pay both.
Same rule on every road, in every season.
Alpine passes above 1,000 m can close to summer-tire traffic first when conditions turn.
Look for the round blue chain sign near pass approaches in winter.
Unlike Germany or Austria, no Swiss city restricts entry by emissions class.
Speeding fines scale with how far over you were and can run into the thousands of francs.
Works from any phone in Switzerland, even with no local SIM.
Direct lines skip the general dispatcher if you already know which service you need.
