Winter tire requirement in Alpes-Maritimes

From November 1, 2026, to March 31, 2027, drivers in specific mountainous communes in the Alpes-Maritimes region must use winter tires or chains, regardless of weather conditions or the presence of snow.

Regulated communes and equipment

The regulation applies to roads in communes designated by a prefectural decree, published by the Alpes-Maritimes prefecture. These include several mountain communes such as Levens, Sospel, and Tende, but not Nice. Drivers traveling to these areas must ensure their vehicles meet the equipment requirements.

All roads within designated areas

The rule covers all roads within the affected communes, not just high-altitude routes. Entry and exit signs help drivers recognize the regulated zones and adjust their preparations accordingly.

Equipment standards for cars and light vehicles

For cars, light utility vehicles, and campers, drivers can either install four winter tires marked with the alpine symbol (3PMSF) or carry chains or snow socks for at least two driven wheels. The older "M+S" marking is no longer sufficient on its own.

Requirements for larger vehicles

Buses, coaches, and heavy trucks must also comply with the regulation. Heavy trucks towing trailers or semi-trailers need removable anti-skid devices on at least two driven wheels, as specified by the prefecture.

Preparation and awareness

Drivers are advised to check the prefectural list of affected communes before each trip. Those frequently visiting mountain valleys should verify their usual routes and ensure their tires and chains are compatible with their vehicle's wheel size. The regulation is in effect for five months, and a recent reminder urged drivers to prepare in advance for holiday or weekend travel.
