Driving in Switzerland in Winter: Tires, Pass Closures, Chains, and Rental Rules

For a winter rental, confirm the tires, the chain compatibility and the route before paying. A vehicle description such as “SUV” does not answer those questions.

Switzerland has no national calendar-based winter-tire mandate, but the vehicle must remain suitable for the conditions. ASTRA explains the winter-tire rule and the possible consequences of unsuitable equipment.

Build the trip around roads and tunnels available on your dates. A summer pass loop is not a winter route; even roads normally operated year-round can close temporarily.

Ask for a written statement of the tire specification and whether the quoted total includes the winter equipment you need. Do not infer equipment from the country of registration, season or “all-season” label alone.

For a mountain trip, our recommendation is to request tires bearing the three-peak mountain snowflake symbol and verify them at pickup. Ask the desk to check tread depth rather than judging it from a distant glance.

A booking request is useful only if the supplying company confirms it. Keep the confirmation with your reservation, particularly if the car is supplied by a company different from the comparison site.

Furka, Grimsel, Susten and the Gotthard pass road have seasonal winter closures. Opening dates depend on conditions and snow clearance. Check TCS live Swiss pass status and the Alpenpässe road reports for the actual road.

The Gotthard pass road and the Gotthard road tunnel are different routes. Do not follow navigation onto a closed pass because the tunnel route is busy.

Bernina is one example of a pass normally operated year-round. That description does not promise unrestricted access in snowfall; chain requirements or temporary closures remain possible.

Yes when the round blue mandatory-chain sign applies: it shows a white tire-and-chain symbol. The rule requires chains on at least two driven wheels on the same axle, or an officially approved equivalent. TCS explains the sign and fitting guidance.

Winter tires do not replace a chain requirement. AWD or four-wheel drive is not a blanket exemption; follow any explicit supplementary exemption and the instructions for your vehicle.

Ask the supplier to confirm chain availability, cost, the correct size and the permitted axle for the exact car. Before leaving the desk, inspect the set and request a demonstration. Practice somewhere suitable before you need it on the road.

Follow the lower of the road, vehicle and chain limits. TCS advises no more than 50 km/h with chains and prompt removal when the road becomes snow-free. Do not continue onto a signed section if you cannot fit the required equipment.

Do not treat “full cover” as a description of every covered situation. Read the rental agreement and any separate insurance or waiver together, including their excesses and exclusions.

Ask specifically about damage while using chains, tires, wheels, glass and the underbody, plus recovery from a snow-covered access road. If relying on a card benefit, check its rental-country, vehicle and payment conditions.

ECC-Net’s rental guidance recommends checking contract and insurance terms and declaring countries before booking. The questions here are a planning checklist; the answer comes from the policy you buy.
