Current car window tinting law means that both the driver of the vehicle (you) and the installers of the film (us) are under obligation to comply with the law. Tinting Express has a duty to ensure all installations are carried out in accordance with legislation and make no exceptions.
This mainly concerns the glass on the front windows that are forward of the B-pillar. If you’re not sure where your ‘B’ pillar is, then take some time to familiarise yourself with our Motor Vehicle Legislation (PDF), or refer to the diagrams below.
A standard car window allows approximately 80% of the visible light to pass through it. The minimum level of visible light transmission allowable by law for the front doors that have been tinted is 70%. For windscreens, the visible light transmission before or after filming or tinting should not be less than 75%. Most vehicle glass that leaves a manufacturing plant will have been stained to a level of around 72% – 85%, depending on the brand of car.

Tinted vehicle windows: the law
The rules for tinted front windscreens and front side windows depend on when the vehicle was first used. There are no rules for tinting the rear windscreen or rear passenger windows.
Vehicles first used on 1 April 1985 or later
The front windscreen must let at least 75% of light through and the front side windows must let at least 70% of light through.
Vehicles first used before 1 April 1985
The front windscreen and front side windows must both let at least 70% of light through.
Penalties for having wrongly tinted windows
It’s illegal to fit or sell glass (or a vehicle already fitted with glass) that breaks the rules on tinted windows.
The police or the Driver and Vehicle Standards Agency (DVSA) vehicle examiners use light measuring equipment to measure window tint.
If your windscreen or front side windows are tinted too much you could get:
a ‘prohibition notice’ stopping you using your vehicle on the road until you have the extra tint removed
a penalty notice or court summons
