Snow chains required
Mandatory signs

Snow chains required

Fit snow chains as required before continuing.

This sign requires snow chains on the signed road, subject to any applicable exemption. Poland's C-18 requires them on at least two driven wheels.

The common design is a blue circle with a white tyre fitted with chains. France's B26 can also be satisfied by qualifying winter equipment unless an additional plate specifically requires chains.
