The AutoSock Regulations Update for the new Winter Season 2021-2022

Every year the regulations for carrying and using winter traction devices are changing. It is challenging to keep track of legal updates for different regions worldwide. Our seasonal legal update informs you about the usage of AutoSock and where the snow sock is a legally accepted alternative to snow chains.


AutoSock is the first product worldwide to be certified according to the European standard EN16662-1. Following EU procedures, the standard has been implemented as national standard in all EU member states, as well as in Norway, Switzerland, Serbia and Turkey. AutoSock for passenger cars and light commercial vehicles below 3,5 t gross weight can now be used whenever snow chains are mandatory in any country of the EU.

In Switzerland, AutoSock for passenger cars and light commercial vehicles was separately approved on national level and is a legal alternative to snow chains.

In France, the new “Mountain Law” (“Loi Montagne”) regulates that winter equipment must be carried on special road sections in mountainous areas between November 1st and March 31st. AutoSock for passenger cars and light commercial vehicles fully complies with this new regulation and can legally be used instead of snow chains or winter tires when entering any of these areas.
