What is the purpose of the law?

The purpose of the law is to ensure the car drivers’ ability to see the road is not excessively restricted by glass tint.

Legally where do I stand?

You must not drive a vehicle on the road with the windscreen or front side windows excessively tinted. You may also invalidate your insurance with this modification, particularly as the vehicle is likely to be illegal.

What is excessively tinted glass?

Road Vehicles (Construction & Use) Regulations 1986 as amended specify the minimum levels of light that must pass through the windscreen and front side windows. The limits are:

Motor Vehicles first used before 1 April 1985: The windscreen and front side windows must allow at least 70% of light to be transmitted through them.

Motor Vehicles first used before 1 April 1985: The windscreen and front side windows must allow at least 70% of light to be transmitted through them.

Motor Vehicles first used on or after 1 April 1985:The light transmitted through the windscreen must be at least 75%.The front side windows must allow at least 70% of light to be transmitted through them.

If the glass is tinted to a point whereby it lets through less light, then the vehicle does not meet legal requirements

Which windows in the vehicle does this apply to?
