According to Sécurité routière, from November 1 to March 31, light commercial vehicles, as well as trucks without a trailer or semi-trailer, will be required to have 4 winter tires (M + S / MS / M & S) or anti-slip chains on two drive wheels.

In addition, trucks with a trailer or semi-trailer must be equipped with anti-skid chains, allowing them to be mounted on at least two drive wheels, even if the vehicles have winter tires.
These regulations will apply in the upper regions of the country (Alps, Corsica, Massif Central, Jura, Pyrenees, Vosges).
