Tinted Windows & the Law

Tinting is Cool – Right?

Most modern cars have a small level of tinting to their window glass – it looks good and helps keep the sun out when it’s hot. It’s perfectly legal.

However, many people like to go further than this and ‘black out’ their windows – making them look like limousine windows. Indeed, the blackest level of tint commonly available is known in the trade as ‘limo tint’.

As well as looking good (if you like that kind of thing), dark-tinted windows improve privacy and help keep the sun out – but they are only legal on windows behind the front doors of a car.

The law states that front door side windows must let at least 70% of light through.

Front Windscreens must let 75% of light through (70% on cars first used before 1st April 1985).

The reason for this is simple – dark tints restrict visibility in poor light conditions, meaning that you might not see other road users as well as you would with a clear window. The risk is greatest when you are driving at night, when you are effectively driving with dark sunglasses in the dark… It is easy to imagine how tinted glass would prevent you seeing poorly-lit road users, such as cyclists and pedestrians. The consequences could be fatal.

This law is enforced with increasing thoroughness by the Police and by VOSA, who carry measuring equipment to check how much light can pass through a tinted window.

Tinted Windows & The Law

What’s The Penalty?

If your front side windows or windscreen are found to be too heavily tinted, you are committing an offence and one of two things might happen:

  • You could be issued with an Endorseable Fixed Penalty Notice (EFPN) – this means your licence will be endorsed with 3 points and you will be issued with a £60 fine;

  • If your windows are illegally tinted but close to the legal limit, it is possible you might be let off with a vehicle defect rectification notice, which requires you to have the tint removed and provide evidence that this has been done to a police station (e.g. a garage receipt).

As I’ve already mentioned, the biggest safety risk with tinted windows comes when driving at night. A Traffic Police Sergeant recently contacted me to point out that if you are involved in a serious collision while driving with tinted glass at night, the tinted windows can be used as evidence towards a charge of careless or dangerous driving. These offences carry severe penalties, ranging right up to prison sentences.

Remember, all of this only applies to front side windows (i.e. driver’s door and front passenger door) and windscreens. You can do what you like to rear windows (including the back windscreen).

What Should I Do Next?

If you have had your car’s windows tinted (to a legal level) you should inform your insurance company, as they are likely to consider this to be a modification to your car. Failure to inform your insurance company of modifications can lead to future claims being invalidated.

If you have bought a second hand car with tinted windows and you think the windows may be too heavily tinted, we would suggest one of the following:

  • Have it removed (can often be done with a hairdryer, else ask a garage)

  • Take it to a tinting company or MOT centre and ask their opinion

  • Contact your nearest VOSA test centre, explain that you have just bought the car and ask if they will test it for you.

(Be warned that in a worse-case scenario, VOSA might issue a prohibition and prevent you leaving the test centre before you remove the tint – hopefully they would be reasonable, however, since you brought the car to them voluntarily).

    Turns out it’s a £100 fine 3 points and a prohibition notice with 1 hrs to remove tint. Had bought 2nd hand car been driving it for a year no problem passed umpteen traffic police so figured all was ok. Guess not.

    It is not just about the car driver seeing other road users, it is about other people being able to see the car driver.

    -cyclists, pedestrians and other road users need to see car driver’s eyes to be sure the driver has seen them.
    -in the case of an accident it helps that cameras and bystanders can identify the driver
    -tinted windows help people hide illegal and dangerous behaviour such as using phones or drinking alcohol.

    In addition, tinted windows add the the trend for aggressive looking vehicles, which contributes to an unfriendly environment. All because of the ego of the car driver?

      That is the most blatant improvised utter nonsense I’ve seen in a while on this topic. There is simply no such rule, and never were, with regard to any requirement for “cyclists and pedestrians required to be allowed to see the driver, let alone the driver’s EYE”. That would mean a direct ban on the use of sunglasses whilst driving.

      Due to that trival logical chain, Fergus’ comment above fulfills pretty much all the criteria the deliberate misinformation, and a rather inept attempt at that.

    Just to confirm:

    Because the 75% front windscreen and front side window light permability requirement (70% for old cars) relates to light transmission IN THE INWARD DIRECTION ONLY, it is also trivial the regulation is purely and solely about the driver receiving sufficient information through the windscreen & front windows. It is also not only not required, but explicitly discouraged to drive with internal lights on at night, so what do you think you need to do at night when pedestrians don’t see into a vehicle without any tint on any windows? Unless you’re one of those loonies who’d support curfew for men / ban driving at night / etc., in which case the only cure for you is a lifetime assignment to a guarded mental institution for the deranged terrorist you are.

    Unfriendly environment?
    What have you smoked, really?
    The environment doesn’t owe you any friendship.
