Warning signs
Risk of ice or packed snow ahead
What it means
The snowflake triangle warns that the road ahead may be iced over or covered in packed snow. It is temporary, put out in bad spells and removed afterwards, so if it is up, take it seriously. Drop your speed, avoid sudden inputs, and hold well back: stopping distances can be ten times greater.
