Riding and Driving in Heavy Rain
Rain changes how a vehicle grips, stops and is seen. A few adjustments make wet journeys far safer, especially on two wheels.
Grip and aquaplaning
Aquaplaning happens when a layer of water builds up between the tyres and the road, so the tyres lose contact with the surface. Worn tread, high speed and standing water all make it more likely.
Adjust your riding and driving
- Slow down and increase following distance considerably.
- Brake, steer and accelerate smoothly; sudden inputs break grip.
- Avoid road markings, metal covers and leaves, which are slippery when wet.
- On two wheels, stay upright through puddles and brake before a bend, not in it.
Be seen
Use dipped headlights in rain. Riders should wear bright or reflective layers; a dark rain cape at night is almost invisible.
After the rain
Check that brakes work properly after riding through deep water, by braking gently a few times at low speed. Dry and lubricate a bike chain after a wet ride.
When not to go
If the road is flooded or visibility is very poor, the safest journey is the one postponed.
