When should you use fog lights?

You should only use fog lights when visibility drops below 100 metres (about the length of a football pitch). This usually happens in thick fog, heavy snow, or very heavy spray.

Is it illegal to use fog lights when it’s not foggy?

Yes. Using fog lights when visibility is good can dazzle other drivers and is against the Highway Code. You could be fined for improper use.

What’s the difference between front and rear fog lights?

Front fog lights help you see the road edges in poor visibility. Rear fog lights are much brighter and help drivers behind you see your vehicle from a distance.

Do all cars have front fog lights?

No. Many cars only have rear fog lights as standard. Front fog lights are optional on some models.

When should you turn fog lights off?

As soon as visibility improves above 100 metres. Leaving them on in clear conditions can blind or irritate other road users.

Can fog lights replace headlights at night?

No. Fog lights are not designed to illuminate the road ahead like headlights. They should only be used alongside normal lights when conditions require them.

How do you know if your fog lights are on?

Your dashboard will show a warning symbol. Rear fog light symbols are usually amber, while front fog light symbols are green.

Do fog lights help in heavy rain?

Only in extremely heavy rain where visibility is severely reduced. In normal rain, dipped headlights are sufficient.

Are fog lights needed for the driving test?

You won’t usually be asked to use them, but you should know what they do and when to use them correctly as part of safe driving knowledge.

Why are rear fog lights so bright?

They are designed to cut through dense fog so drivers behind can see you earlier, reducing the risk of rear-end collisions.

Phase 3: Test Ready

How to Book Your Driving Test

The official way to book your practical test and manage your own booking through GOV.UK.

Need help understanding the new rules?

Driving test bookings and changes must now be managed by the learner directly through GOV.UK. We can no longer search for cancellations, use cancellation checkers, or change a driving test booking on your behalf.

We can still support you with advice, test readiness and vehicle availability. If you find a suitable test date yourself, speak to your instructor before changing it to make sure you are ready and the car is available.

Read the New Rules

⚠️

Avoid Unofficial Booking and Cancellation Services

Only use official GOV.UK services to book, change or cancel your driving test. Unofficial cancellation checkers and third-party booking sites may charge extra fees and may not be able to help under the new rules. A standard official weekday car driving test is £62.
