Help & Advice: Is It Legal to Drive with a Dirty Windscreen?

Is It Legal to Drive with a Dirty Windscreen?

Last updated on February 26th, 2021 What does this mean?

Visibility whilst driving is key to operating your vehicle correctly, so if you’re driving with a dirty windscreen, it’s likely you’re impeding your ability to drive safely. Previously, we’ve discussed the dangers of driving with a messy car, but what about driving with a dirty windscreen?

Why do I need to have a clean windscreen?

The Highway Code for the UK explicitly states that ‘windscreens and windows MUST be kept clean and free from obstructions to vision’ to ensure optimum safety when driving your vehicle. A dirty windscreen, as well as side windows, side mirrors and the back window, can create blind spots for the driver, therefore rendering the vehicle unsafe to drive. 

What determines the difference between unclean and illegally dirty?

Windscreens naturally get dirty over time, but what determines the difference between an unclean windscreen and an illegally dirty windscreen? If your line of vision is obstructed in any way, this is classed as illegal and leaves you liable to a fine. 

What are the legal consequences?

A dirty windscreen could land you a fine of £1000, so it’s worth keeping your windscreen clean to not only avoid the fine, but to keep yourself, passengers and pedestrians safe too. 

Top tips for keeping your windscreen clean and clear

A windscreen can be dirtied or obstructed for a variety of reasons, including:

  • Dirty windscreen wipers
    The main component of your car that cleans your windscreen is your windscreen wipers. If you find it’s difficult to keep your windscreen clear whilst using them, it might be time for a new pair. Click here for information on cleaning your windscreen wipers. 
  • Demist
    Windscreens often get misted when it’s cold outside, so it’s crucial you clear your windscreen before you begin driving. Most cars have a windscreen demister button that blows air onto the inside of your windscreen to help clear the mist faster. Putting the air-con on will also help reduce mist on the windscreen, as it dries out the air in the car.
  • Windscreen damage
    A damaged windscreen can certainly impair your visibility – as well as causing a distracting glare when the sunlight shines on the cracks in the glass.
