15FALLING OR FALLEN ROCKS

---

May be used with diagram 570. The symbol is reversed when the hazard is on the right hand side of the road

15.1 The falling or fallen rocks sign, diagram 559, should be used where there is a danger of rocks falling onto a road. A sign to diagram 570 indicating the length of road likely to be affected may be used with the sign. The symbol may be reversed when appropriate, but where rocks might fall from either side (e.g. in a gorge) the sign should be used as illustrated.
