Protecting your car from severe weather: before, during and after

In the last few years, we’ve seen extreme weather like storms and flooding become more common.

And for our cars on the road, these natural events can cause all sorts of problems.

Here’s how you can protect your car from some of the most common dangers nature can throw our way.

General tips

It’s a good idea to keep up to date with the local weather forecasts. You’ll have to make a judgement call on if it’s worth driving in the first place.

If the forecast doesn’t look good, you could consider using public transport instead of driving. And if the buses and trains are cancelled, it could be a sign that it’s too risky to head out in your car.

Storms and strong winds

Try and keep your car parked in a garage or sheltered area if you can. This should minimise any potential damage from happening.

If possible, secure or remove anything that is attached to your car (like a roof rack). Strong winds and gusts could turn loose objects into projectiles.

Heavy rain

It seems a given but make sure all windows and sunroofs are securely closed. It’s also worth checking your wiper blades, too - just in case they’re worn and need replacing.

Consider using winter or all-weather tyres if you have them. And don’t forget to check the tread depth of your tyres. The minimum legal limit in the UK is 1.6mm, although many car manufacturers recommend 3mm.

Flooding

Avoid parking your car in low areas known for flooding. If you need to drive, it’s worth planning alternative routes that stay clear from flood-prone areas.

Freezing temperatures

Cold weather can strain your car battery, and it also takes more power to start a cold engine. Get it checked and make sure your battery is fully charged. Find out more about how to get your car ready for winter.

Driving in severe weather

No one wants to, and sometimes it can’t be avoided... but if you find yourself on the road when bad weather arrives, here are some handy tips to follow:

Storms and strong winds

Be aware of gaps between cars and buildings that could be easily blown by side winds.

Leaving bigger gaps between yourself and the car in front gives you more time to react to any potential dangers or accidents that have happened.

Heavy rain

Try not to drive through large puddles of water if you can. This could result in aquaplaning which will give you less control of the car.

When it’s harder to see or there’s a build-up of water on the road, reduce your speed and turn your headlights on to improve your vision and ability to respond to hazards.

Stick to main roads if you can, as these should be better maintained and safer to drive on compared to country roads.

Flooding

Don’t drive on flooded roads or through any flood water. If your route is blocked, try and park somewhere safe so you can find a different way to your destination.

Can’t park somewhere safe? If you have a voice-controlled smartphone or sat-nav built into your car, ask your device to give you a different route (to save you having to do this manually).

Freezing temperatures

To keep yourself comfortable and your windscreen clear, keep a warm flow of air circulating in your car. To remove any moisture build-up or condensation from forming, turn on the air conditioning or slightly open the window for a moment if it’s not raining.

Freezing temperatures can also mean ice on the roads, so take care especially when driving on roads that haven’t been gritted – drive slower around corners and bends to reduce any chance of drifting.

Hopefully you’ve arrived safely at your destination. Once the bad weather clears, or before you drive again, follow some of these basic checks to make your journey as smooth as possible:

Storms and strong winds

Check your car for any dents and damage that might need repairing. It's a good idea to do this as soon as possible as you’ll know if any damage has been caused by the severe weather.

Heavy rain

Make sure water hasn’t leaked inside your car. If it has, try and keep your car under shelter, or securely wrapped with a waterproof cover.

Once the bad weather passes, investigate the location of the leak so you can get this fixed.

Flooding

Don’t try and start a car that’s been in flood water. Get a professional to check your car for any engine or electrical damage.

Freezing temperatures

Park your car under cover or in a garage to help reduce any icy patches from forming again.

Cleaning your windows from condensation with a dry cloth will also help, too.

If you wanted to be a bit more thorough, you could check your car battery, wiper blades, fluid levels and brakes – but if you’re not planning to drive again for a while, do this a little closer to your next trip.

Sometimes, no matter how well you prepare, things can be out of your control. That’s why it’s a good idea to know what you're covered for under your car insurance policy, for added peace of mind.
