A Guide to Driving in Fog

Last Updated on January 23, 2025

Driving in fog can be one of the most challenging and nerve-wracking experiences for any motorist. Low visibility conditions reduce your ability to see other vehicles, pedestrians, and important road markings, significantly increasing the risk of accidents. For learner drivers or those with limited experience in such weather, it can feel particularly daunting.

However, understanding how to safely navigate through foggy conditions and knowing how to use your vehicle’s features effectively can make a significant difference. By following the correct techniques and adhering to essential road safety practices, you can approach driving in fog with confidence and reduce potential hazards. In this comprehensive guide, we’ll explore the dangers of fog, provide practical tips to enhance your safety, and clarify the role of fog lights in these conditions.

What is fog?

Fog is a thick cloud of tiny water droplets suspended in the atmosphere near the ground, reducing visibility significantly. It can form under specific weather conditions, particularly when there’s high humidity and a drop in temperature. Driving in fog requires heightened awareness and adherence to safety guidelines to prevent accidents.

What can I do to make driving in fog easier?

There are a number of tips that you can follow that will help you to drive safer in fog, they include:

• Reducing your speed and increasing the distance between you and the car in front to give you longer to react.
• If you really begin to struggle to see in front of you, find a safe place to pull over and park until it passes.
• Using your fog lights (if they’re fitted to your car) or low beams. Avoid using high beam lights as they can reflect off the fog and dazzle other road users.
• Staying aware of your surroundings, listening for other vehicles, and avoiding distractions inside the car.

What are fog lights?

Unlike standard headlights, fog lights are designed to improve the driver’s visibility in foggy conditions. Fog lights work by cutting through the fog and illuminating the road underneath.

Your car may have a set of front and rear fog lights.

The front fog lights are usually a white or yellow light which tends to sit below the car headlights.

Rear fog lights are red, similar to brake lights, and they help drivers behind see you car a little easier.

Does my car have fog lights?

All cars are legally required to have rear fog lights, whereas front fog lights are often included in mid to higher-spec cars.

You can check your dashboard, steering wheel stalk or your car’s handbook to check if your car has front fog lights.

When should I use my fog lights?

The Highway Code states that you must use headlights if you cannot see more than 100m (328 feet) in front of you. Likewise, you must turn your fog lights off when visibility improves to stop dazzling other drivers. Failing to use fog lights when needed or using them incorrectly could result in a £30 fine.

It’s important to note that relying on automatic lights isn’t always enough. Automatic headlights are light-sensitive and may not activate during foggy conditions if it’s still bright outside. Be sure to switch on your fog lights manually when needed, as outlined in your car’s handbook.

Can I use fog lights instead of my headlights?

No, your fog lights should never be used as a substitute for headlights. They are specifically designed for use in foggy conditions. Driving with only fog lights in clear conditions is not only unsafe but can also result in fines.

Can I drive through fog with broken fog lights?

Front fog lights are optional, and not all cars are fitted with them. However, rear fog lights are a legal requirement. If your rear fog lights are broken, you must get them fixed as soon as possible. Regularly checking your car’s lights is essential to ensure they are working properly.

Additional Tips for Driving in Fog

• Turn on your heater and demisters: This will help prevent your windows from fogging up further and reduce the chances of obscured vision inside your vehicle.
• Use your wipers: Light mist or condensation from fog can collect on your windscreen, so keep your wipers active to maintain a clear view.
• Avoid overtaking unless absolutely necessary: The limited visibility makes judging distances extremely difficult, so proceed cautiously.
• Plan your route and allow extra time: Check local weather reports to understand how long the fog may last and consider delaying your journey if conditions are severe.
