Question to the Department for Transport:

To ask the Secretary of State for Transport, whether she plans to require MOT tests to check that (a) front windows and (b) windscreens comply with legal light transmission limits.

Driver visibility is an important safety consideration at the MOT, with the tester required to check the driver’s field of vision for obstructions. This includes inspecting the windscreen and front side windows for excessive tinting and discolouration. The MOT tester will fail the vehicle if the windscreen or window are excessively tinted and visibility through the swept area of the windscreen, or of an obligatory external mirror, is seriously affected.

This approach aligns with legal light transmission levels that are intended to ensure the driver has good visibility of the road for safety purposes.
