What to do
Watch the road surface ahead and be ready to steer around rocks safely. Slow down, keep your eyes on the pavement, and never stop under a rocky slope or swerve into oncoming traffic.
Where you see it
In mountain and hilly areas with rocky cuts or cliffs beside the road.
Test trap
The sign warns mainly of rocks that may already be in the road, not just rocks falling on you. So the best habit is to watch the roadway, not the hill above.
Memory tip: Rocks on the slope, rocks on the road: eyes on the pavement.
