Mandatory winter equipment
Following implementing decree no. 2020-1264 published in the Official Journal of October 16, 2020, the prefects of the 48 “mountain” departments have the power to make it compulsory to equip vehicles with winter tires, chains or socks .
Indeed, in order to limit traffic jams on the roads in mountainous regions but also to improve user safety, you will need to equip your car with winter tires or chains during winter in certain municipalities . Failure to comply with this law may result in significant penalties.
When will this equipment be needed?
The decree will come into force on November 1, 2021 and will be applicable for each winter period (from November 1 to March 31).
- M+S (Mud&Snow) tires will be tolerated until November 1, 2024.
- 3PMSF (3 Peak Mountain Snow Flake) tires will be compulsory from November 1, 2024 (end of transitional period).
A transition period of 3 years is granted to M+S tires alone, i.e. until November 1, 2024. Beyond that, all vehicles concerned circulating in the municipalities designated by the prefects of the 48 departments must be equipped with 3PMSF tires.
The 3PMSF symbol (3 Peak Mountain Snow Flake) is easily recognizable: a snowflake surrounded by 3 mountain peaks (and always accompanied by the M+S logo). The 3PMSF marking is issued by a certified laboratory, which guarantees an optimal level of performance and safety on snow.
