1. Rockfall

A rockfall warning indicates a road section where rocks or stones may fall from a cliff, cutting or steep slope, or where fallen material may already be present on the road. The danger may affect the full carriageway and can appear suddenly.

Drivers should reduce speed, scan the road and slopes ahead, increase their following distance and remain prepared to stop. They should avoid unnecessary stopping in the exposed section and never attempt to move unstable rocks themselves.

Where might falling rocks be a hazard on roads in the Philippines?

Watch for falling rocks beside steep slopes and cuttings. Heavy rain or slope works can increase the hazard. Follow warnings and closures, slow to the conditions and look for material already on the road.

Does a falling-rocks warning sign in the Philippines impose a speed limit?

A falling-rocks sign is a hazard warning, not normally a numerical speed-limit sign. Follow any separate speed or closure signs, slow down to match visibility and conditions, and watch for material already on the road.

What should you do if rocks are blocking the road in the Philippines?

Slow or stop in a safe place away from the exposed slope if possible. Do not drive over unstable debris or stop beneath a cliff unnecessarily. Follow any closure or traffic-control instructions and report a dangerous obstruction through the appropriate road authority or emergency channel.
