Falling Rocks (Right) Sign
Shape: Equilateral triangle (pointing up) · Colour: Yellow/white with red border
Risk of rocks or debris falling from the slope on the right side of the road.
What It Means
Falling rock zones are common on India's mountain highways through the Himalayas, Western Ghats, and Eastern Ghats. Rocks can fall without warning — triggered by rain, frost, blasting, seismic activity, or simple erosion. Being hit by a falling rock at highway speed is almost always fatal. After heavy rain, the risk is significantly elevated.
📍 Where You'll See It
On mountain roads, roads cut through hillsides, and sections where the rock face is directly above the carriageway.
✅ What You Must Do
Increase speed (within limits) to spend minimum time under the rock face. Do not stop under the slope for any reason — not for a photo, phone call, or break. Look up and watch for movement.
⚠️ Common Mistake
Pulling over in a rockfall zone to answer a call or take photographs. This is exactly where you should spend the least possible time.
⚖️ Legal Note
No penalty for the sign, but NHAI/state road authorities are liable for known rockfall hazards without warning signs.
