Rare

Falling Rocks

What It Means

A yellow diamond showing rocks tumbling toward a stylized cliff or car, warning that loose rock or debris may fall onto the roadway from an adjacent slope.

How Rare Is It on Road Sign Hunt?

Rare. Worth a detour through the right kind of road.

Spotting Tip

Mountain passes and roads cut through rock cuts or canyons are where these appear — a genuinely rare sighting unless your trip goes through serious elevation change.

Fun Fact

These signs mark areas with a documented history of rockfall, not just any hilly terrain — highway departments monitor unstable slopes and post the sign where rock has actually come down before.
