Switzerland Tyre Rules 2026: No Winter Tyre Season

Switzerland is the Alpine country without a winter tyre law. There is no dated season, no marking requirement and no line in the rulebook that says a particular tyre must be fitted between particular months.

What exists instead is a general duty: the vehicle must be in a condition fit for the road it is on. On a December afternoon on the Julier that is a demanding standard, and it is the one that actually bites. Tread must clear 1.6 mm, the floor set out in Council Directive 89/459/EEC, and worn tyres draw a CHF 100 fine in any month.

Tyre Law Summary for Switzerland

The duty that replaces the season

Countries with a dated rule tell you when to change tyres. Switzerland tells you to arrive with a car that suits the road, and leaves the judgement with you. The practical consequence is not a roadside tyre check in November; it is what happens when a vehicle that could not climb a pass ends up across it.

At that point the question is the obstruction, the recovery and the liability — and the driver who chose summer tyres for an Alpine crossing in January is the one holding all three. The absence of a season is not permission; it is the removal of a defence.

The blue sign is the hard rule

There is one winter obligation in Switzerland that is unambiguous, and it is not about tyres at all. The round blue sign showing a chained wheel makes snow chains compulsory on that stretch of road, whatever is fitted to the car. It goes up when conditions require and comes down when they clear.

Two things follow. Chains are worth carrying for any Alpine route in winter even on good winter tyres, because the sign does not care what you are running. And the decision is made on the day by the road authority, so the planning question is the pass status, not the date.

Studded tyres are restricted

Studs are a restricted fitment here rather than a free choice. Their use is bounded by season and by road class, and they are not a fitment for the motorway network — which for a country whose main transit routes are motorways makes them a specialist answer rather than a general one. Confirm the current restriction before fitting them for a trip.

Tread, altitude and the 4 mm figure

The legal floor is 1.6 mm and the fine behind it is CHF 100. For Alpine winter driving the working figure is 4 mm: below that a winter tyre’s blocks are too shallow to hold snow against snow, which is the mechanism it relies on. That is a performance threshold rather than a statutory one, and it is the number worth measuring against in November.

Altitude also makes a mockery of averages. Geneva at 375 metres and the Furka at 2,429 metres are the same country and the same trip, and the temperature between them can differ by fifteen degrees on the same afternoon.

How the neighbours differ

Switzerland is the odd one out. Four of its five neighbours run some form of seasonal or conditional obligation:

• Austria: an obligation running 1 Nov – 15 Apr. The strictest line you will cross from here.
• Italy: orders applied road by road and region by region within a 15 Nov – 15 Apr window.
• France: the mountain law, 1 Nov – 31 Mar in designated departments — which covers the Alpine and Jura communes along the Swiss border.
• Germany: a situational duty triggered by ice, snow, slush or black ice rather than by date.
• Liechtenstein: the fifth neighbour, entered from the Rhine valley near Buchs, and easy to forget on a list.

Driving out of Switzerland in winter can therefore mean driving into a requirement you did not have at the start of the day.
