UK Window Tint Laws

In the United Kingdom, window tint rules are straightforward and easy to understand.

If you wish to add window tint to your vehicle in the UK, you must adhere to specific regulations regarding visible light transmission (VLT).

Let’s discuss the regulations for window tinting in the UK.

About Window Tinting

Window tinting is the process of adding a thin coating to the inside or outside of a car’s windows in order to cut down on heat and sunlight entering the cabin.

Due to their aesthetic appeal, privacy advantages, and heat-reduction capabilities, window tints are often chosen by drivers.

It is important to remember that the UK has strict rules limiting the transparency and darkness of tinted windows.

Legal Requirements for Vehicle Window Tints

The UK has established rules for the acceptable darkness levels of window tinting in order to protect the safety of vehicles and pedestrians. The Visible Light Transmission (VLT) %, which measures how much light can travel through the windows, is the main subject of these standards.

Front Windscreen

The front windshield must in the UK permit a minimum of 75% VLT. This suggests that the glass must let at least 75% of light flow through. To maintain good visibility, particularly at night or in bad weather, it is necessary to follow this criterion.

Front Side Windows

The front side windows—those that are next to the driver and front passenger—must also adhere to strict requirements. These windows must have a VLT of at least 70%. With this standard, drivers are guaranteed a clean line of sight, and any potential dangers brought on by poor visibility are reduced to a minimum.

Rear Side Windows and Rear Windscreen

Compared to front windows, rear side windows and the rear windshield have somewhat more flexible rules. These windows’ VLTs might be as low as 75%. The driver must have a clear view of the road via the vehicle’s wing mirrors, it is important to remember.

Exceptions and Exemptions

Although the rules mentioned above apply to the majority of vehicles, there are a few exceptions and exclusions that should be noted.

Medical Exemptions

Drivers who must restrict their exposure to sunlight due to an authorized medical condition may be permitted from the rules governing window tint.

However, gaining such an exemption requires the submission of accurate medical paperwork and clearance from the relevant authorities.

Historic Vehicles

Classic automobiles and other historical cars could be excluded from the stringent window tint rules. However, it’s important to confirm specific rules and limitations depending on the category and age of the vehicle.

Consequences of Non-Compliance

Various fines and legal penalties can arise from violating UK window tint laws. Penalties for breaking the law include paying fines, receiving points on your license, and even having to have your windows tinted. Understanding and following these rules is important if you want to stay out of trouble.

Important: Vehicles Used Before 1 April 1985

The regulations mentioned earlier only apply to vehicles that were put into service after 1 April 1985.
