Driving Switzerland in Winter: The Winter-Tyre Myth, Snow-Chain Rules & Ski-Season Costs

Every November, the same claim circulates in expat forums: "Winter tyres aren't mandatory in Switzerland, so I don't need them." The first half is true. The conclusion is dangerous nonsense.

Switzerland — unlike Germany and Austria, which have situational winter-tyre mandates — has no law naming winter tyres. What it has instead is stricter in practice: Art. 29 & 31 of the Road Traffic Act (SVG). These require every driver to keep the vehicle in a roadworthy, safe condition and to remain in control of it at all times, in all conditions. Police and courts interpret that to mean: if you slide into a junction on summer tyres in a snowstorm, you broke the rule the moment you lost control.

The insurance angle is the one expats miss. Swiss insurers cover accidents, of course — but if the accident report notes inadequate tyres for the conditions, the insurer can invoke gross negligence and reduce its payout or reclaim costs from you. The ~CHF 100 fine is the cheap part.

If you are still converting your foreign licence or importing a car, start with our driving licence exchange guide — then come back here before the first snowfall.

Snow chains are not a general requirement. They become mandatory only where the round blue snow-chain sign is posted — typically on steep resort access roads after heavy snowfall. When that sign is up:

• Fit chains to the drive axle (front wheels on front-wheel drive, rear on rear-wheel drive; check your manual for AWD).
• Snow socks are not a legal substitute at a signed chain control, whatever the packaging claims.
• Practise once on dry ground in your driveway. A ski-resort car park at −8 °C in the dark is the worst possible classroom.
• Drive 30–40 km/h max on chains and remove them on cleared tarmac.

Pass closures: many high Alpine passes close roughly from October to June. The winter alternative is the car-train (Autoverlad) — you drive your car onto a flatbed wagon and ride through the tunnel:

Graubünden drivers feel this most — the canton is a web of seasonal passes. Our canton Graubünden page covers local registration, costs and mountain-life specifics if you are settling there.

Winter driving is half the equation; the other half is what the season does to your budget. Three levers matter most:

1. Day tickets vs passes. Large resorts price day tickets roughly in the CHF 60–100 band. Multi-resort season products like the Magic Pass or a regional season pass break even somewhere around 7–14 days — run your own numbers in the calculator above with current prices. Prices change every season, so verify before buying.
2. Gear: rent vs buy. If you ski fewer than ~10 days a season, renting (or a season-long rental from a sports shop) usually beats buying once you count servicing and the speed at which beginners outgrow entry-level skis. Families should look at season rentals for children — kids outgrow boots annually.
3. Heating and Nebenkosten. In a rental flat, winter shows up in your ancillary costs (Nebenkosten). Heating is the biggest swing item — expect the annual reconciliation to claw back CHF 300–800 after a cold winter if your advance payments were set low. Short daylight (dark by ~17:00 in December) also nudges electricity use up.

Budgeting the full picture? The cost-of-living calculator models canton-by-canton budgets, and the relocation cash calculator covers the deposit-heavy first months.

• Strassenverkehrsgesetz (SVG) Art. 29 & 31 — roadworthiness and control of vehicle (Fedlex).
• Fedro/ASTRA — winter equipment recommendations and pass-closure information.

• BLS / Matterhorn Gotthard Bahn — Autoverlad car-train schedules and prices.
• SVG Art. 32 — obligation to adapt speed to conditions.

Book your tyre change for October, not for the morning after the first snowfall — every garage in the country is slammed that week.
