Risk of falling or fallen rocks ahead
A red triangle with rocks tumbling from a cliff face warns that loose rock from the cliff or hillside above the road may fall onto the carriageway. Reduce speed, scan the road surface for fallen debris, and don't stop under overhangs. Common after heavy rain or freezing weather.
