Driving in the rain can be dangerous, especially if your windscreen fogs up and limits your vision of the road.

The UK weather is unpredictable. One minute you're driving along and enjoying the sunshine, and the next you're stuck in a torrential downpour.

Being in your car during stormy conditions can be dangerous and comes with a whole host of hazards, and we all know how important it is to make sure we slow down and stay vigilant when it's chucking it down.

One of the most annoying things about driving in the rain is having your windscreen fog up on the inside. This is caused by condensation that forms when the inside of your car is warmer than the outside, and it can impair your vision when you're on the road so should be cleaned off immediately.

And thankfully, there's an easy way to get rid of it and make sure it never comes back - all with the press of a button.

In a YouTube Shorts video shared by @automartkm, it was revealed that your car should have a button that allows you to defog your windscreen just by using your car's air conditioning.

The poster shared that if you use towels or just your hand to wipe at the condensation on your windscreen, you'll notice that it comes back in just a few minutes, as it doesn't solve the heat imbalances in your vehicle. Instead, you should turn on your car's air conditioner and use a special setting that clears the glass in seconds.

A voiceover in the clip advised: "Instead, we just need to turn on the air conditioner. Turn on the front windshield defogging switch, and after a while, all the fog on the glass will disappear."

You'll want to look for a specific switch in your car that's responsible for controlling the air conditioning flow. It's not just about choosing between having the blast on your feet or face; there's a particular setting symbolised by wavy lines within a rectangle that's the one you need to select.

Some viewers of the video mentioned that this tip was "obvious" to them, and indeed, for those who've been driving for years, it might be second nature. However, for many new drivers unfamiliar with their vehicle's more subtle features, the guidance was a welcome revelation.

One individual expressed their gratitude, commenting: "Thank you, you are my saviour! ".

While another viewer suggested using the heater instead of air conditioning to clear the fog, someone else chimed in to say that cold air is actually more effective for "fast defogging".
