Driving on Mountain and Hill Roads
The vehicle going uphill has right of way. Use low gear for descents. Sound horn at blind curves.
On hill roads: the vehicle going uphill has right of way. Use engine braking (low gear) on descents. Sound your horn before blind curves. Never overtake on curves or near ridges. Park in gear with the handbrake engaged and wheels turned toward the hill.
Penalty Under Law

What the Law Says
CMVR Rule 3 applies general safe driving rules to hill roads. The convention (enforced by BRO and state traffic police on hill roads) is: the vehicle going uphill has right of way — the downhill vehicle must stop and give way. This is because stopping and restarting on a gradient is harder (and more dangerous) for an uphill vehicle, especially heavy ones.
💡 Why This Rule Exists
Mountain roads have unique hazards: narrow widths, hairpin bends with zero visibility, steep gradients, loose rock, and sheer drops. Brake fade (overheated brakes losing effectiveness) is a real danger on long descents. Many fatal hill road accidents involve vehicles whose brakes failed on a descent — engine braking is the only reliable way to control speed on prolonged downhill stretches.
Key Facts
- 1
Uphill vehicle has right of way — downhill must yield and stop.
- 2
Use low gear (1st or 2nd) for long descents — engine braking saves your brakes.
- 3
Sound horn before blind curves (BRO signs say "Horn Please" for this reason).
- 4
Never overtake on a blind curve or near a ridge.
- 5
Keep to the mountain side (left) — not the valley side.
- 6
Park: engage handbrake, leave in gear, turn front wheels toward the hillside.
- 7
Carry chains in winter (snow regions) — mandatory in many Himalayan areas.
⚠️ Common Violations
- ›
Overtaking on blind hairpin bends.
- ›
