Warning signs

Ice or snow

Snow or ice may make the road hazardous, so reduce speed and expect reduced grip.

Drive gently, leave more room to stop and avoid sudden steering or braking. Grip may vary along the affected section, so adjust your speed to the conditions.

The United Kingdom’s 554.2 uses a red-bordered triangle containing a black snowflake. France’s AK14 is a general temporary danger sign, which can be accompanied by a panel identifying icy conditions.
