RockfallBrussels
31. 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.
