Driving in Rain and Waterlogged Roads
Reduce speed, increase following distance, and never drive through water whose depth you cannot gauge.
In rain: reduce speed by 20–30%, double your following distance, use low-beam headlights (not hazard lights), and avoid waterlogged roads where you cannot see the road surface. Aquaplaning (tyres losing contact with the road) begins at as low as 60 km/h on standing water.
Penalty Under Law
₹500 (Sec. 177) for dangerous driving in rain. Sec. 184 if accident caused.

CMVR Rule 3; MV Act Sec. 184 (if driving dangerously in rain)
What the Law Says
CMVR Rule 3 requires driving with "reasonable consideration" for conditions. In rain, the road surface loses 30–50% of its grip. Driving at a speed that causes loss of control in wet conditions is negligent driving under Sec. 184. There is no specific "rain speed limit" in Indian law, but driving at a speed inappropriate for conditions is an offence.
💡 Why This Rule Exists
India's monsoon season (June–September) is the deadliest period for road accidents. Wet roads reduce tyre grip, reduce braking effectiveness, reduce visibility, and hide potholes and open manholes under standing water. Aquaplaning — where a film of water lifts the tyre off the road surface — makes the vehicle completely uncontrollable.
Key Facts
- 1
Reduce speed by 20–30% in moderate rain.
- 2
Double following distance (4-second rule instead of 2).
- 3
Use low-beam headlights — NOT hazard lights (hazards disable your indicators).
- 4
Avoid standing water: hidden potholes and open manholes can swallow a vehicle.
- 5
Aquaplaning risk: begins at ~60 km/h on standing water.
- 6
If aquaplaning: do NOT brake. Ease off the accelerator and hold the steering straight.
- 7
After driving through water: test your brakes gently.
