What is aquaplaning and how to avoid it

In a country as prone to rain as the UK is, it’s no surprise that aquaplaning is a concern for our drivers. Aquaplaning can happen when you’re driving on roads that have a layer of surface water and because that’s something most drivers are likely to encounter at some point, it’s a good idea to make sure you know what aquaplaning is – and what you can do to avoid it.

What is aquaplaning?

Aquaplaning is an issue where you lose control of your car when driving on wet surfaces. It happens when a layer of water gets between a car’s tyres and the road. Aquaplaning greatly increases the chance of a collision or accident. This is because the tyres are unable to grip the road or gain the necessary traction for you to properly steer, brake or accelerate.

Aquaplaning is sometimes also known as hydroplaning, which describes exactly the same kind of experience.

When am I at risk of aquaplaning?

You’re most at risk of aquaplaning when there’s been a heavy rainfall and you’re driving on roads that have lots of dips, depressions and ruts. You only need a build up of 2.5mm of water to be at risk.

You’re also more at risk if you’re driving at speed. This is one of the reasons it’s so important to drop your driving speed when you’re out in wet weather. It’s also essential to keep your tyres well maintained, as threadbare tyres are more likely to cause you to aquaplane. A deep tread is more efficient at helping you clear the water and drive safely.

What to do if you’re aquaplaning

If you’re driving on a wet road and feel your steering become ‘light’, notice the engine suddenly get louder, feel as though you’ve dropped the clutch, or you notice that the rear of the car has started to fishtail, it’s likely you’re aquaplaning. Here’s what to do about it.

• First of all, don’t panic and make sure not to hit the brakes hard
• Instead, gently ease off the accelerator
• Hold the steering wheel as straight as you can
• If you have cruise control on, switch it off
• When you feel yourself regain control of the car, you can start to brake

Taking these slow and steady steps means you’re much less likely to skid or slide.

How to avoid aquaplaning

While it may not be possible – or realistic – to avoid driving when it’s wet outside, there are a few things you can do that will make aquaplaning much less likely.

• Make sure your tyres are well maintained and that the tread is in good condition
• Don’t drive too fast, especially when it’s raining or when it’s been raining recently
• Avoid sudden actions and stay steady and calm if you think you may have hit a wet patch
