Aquaplaning (Hydroplaning)
Aquaplaning is when a layer of water lifts the tyre off the road, causing loss of steering and braking.
What is Aquaplaning (Hydroplaning)?
Risk rises with speed, water depth and worn tread. Wide tyres and low pressure increase it. Steering may suddenly feel light. Tread depth has a big influence: worn tyres can start to aquaplane at much lower speeds than new ones. Ruts filled with water are especially risky. Cruise control should be switched off in heavy rain so you control the throttle. Correct tyre pressure helps the tread channel water away.
How it works
Water cannot escape fast enough from under the tyre.
Why it matters for your car
Ease off the accelerator and keep the wheel straight. Reduce speed in heavy rain.
