Some info on tinted windows.

Tinted Windscreens, windows

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 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.

Legally where do I stand?
If you are the driver -
- 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.

If you are a tinting company -
- You must not modify, or offer to supply, a part that when fitted to a vehicle means that it does not comply with Construction & Use Regulations.

If you're selling a vehicle with extra tinting applied to the windscreen or front side windows - - The vehicle may now have glass that is darker than permitted by Construction & Use regulations, in which case the vehicle should not be sold.

Why are tinted windows not included in the MOT test?
Excessively tinted glass is seen as a serious issue but one which currently affects only a small number of the 24 million vehicles tested annually. To include this item in the MOT test would require
all 18,000 garages to incur expenditure on special test equipment and the time taken to carry out an MOT would increase. The MOT fee would have to be raised to cover the extra time and investment.
This extra cost would affect all motorists - all for a small number of vehicles. With the current levels of offending, roadside enforcement is a better route as it targets the offenders while minimising the
cost and inconvenience to compliant road users.
