How to Drive Safely on Wet & Slippery Roads?
Wet and slippery roads reduce tire grip, increase braking distance, and make steering unpredictable. Safe wet-road driving requires reduced speed, increased following distance, smooth movements, and adapted braking technique.
Safe wet-road driving means reducing speed to 50% of normal, increasing following distance to 6+ seconds, using gentle braking and smooth steering, and avoiding sudden maneuvers. Wet roads increase stopping distance by 2–3×.
Step-by-step worked examples
You're driving at 90 km/h on a dry road. It suddenly rains heavily. What speed is safe on the wet road?
Dry-road stopping distance at 90 km/h ≈ 81 m. Wet-road stopping distance at 90 km/h ≈ 162 m (double). Safe wet speed ≈ 60 km/h (stopping distance ≈ 72 m, comparable to dry 60 km/h stopping). Action: Reduce speed gradually and increase following distance to 6+ seconds.
You brake on a wet road and feel the car skid. Your wheels are locked. What is your recovery procedure?
Release the brake to unlock the wheels (restore steering control). If skid continues, steer gently in the direction you want the front to go. Once steering responds, resume gentle braking (avoid full lock again). Key: Modern ABS brakes do this automatically; do not 'pump' ABS brakes.
Heavy rain reduces visibility to 30 metres. What adjustments must you make?
Reduce speed so your stopping distance = your visibility distance (30 m). With stopping distance = 30 m, safe speed ≈ 35–40 km/h on wet roads. Use headlights (low beam) to see and be seen. Increase following distance to 8+ seconds to account for reduced visibility. Key: Your visibility is your speed limit in poor weather.

Common mistakes
Thinking wet-road speed is only slightly slower than dry-road speed. — Correct: Reduce speed by 30–50%; stopping distance doubles or triples.
Assuming 3-second following distance is safe on wet roads. — Correct: Increase to 6–8 seconds to match the increased stopping distance.
Braking harder when you start to skid. — Correct: Release the brake to unlock wheels and regain steering control.
Using high-beam lights in rain to see better. — Correct: High beams reflect off rain; low beams penetrate better.
FAQ
How much does stopping distance increase on wet roads?
Wet-road stopping distance is 2–3× longer than dry-road distance at the same speed. This is why speed reduction is critical.
What is the safest following distance on wet roads?
At least 6–8 seconds behind the vehicle ahead. Compare this to the 3-second rule on dry roads. The extra time accounts for longer braking distance.
What should you do if your car starts to skid on a wet road?
Release the brake to unlock the wheels and restore steering control. Steer gently in the direction you want the front of the car to go. Avoid sudden or harsh movements.
How do weather and visibility affect safe speed on wet roads?
Your stopping distance should never exceed your visibility distance. In heavy rain with low visibility, reduce speed to ensure you can stop within what you can see.
