    Q403: How dark can I tint the windows on my vehicle?

    The requirements for the visual transmission of light are:

    • Motor vehicles first used on or after 1/4/85 - windscreen 75%, other windows (i.e. front passenger windows) 70%.
    • All motor vehicles first used before 1/4/85 - 70%.

    The windows that are exempted from this are the rear windscreen and the rear side windows on both sides.

    Police forces now have equipment that can measure light transmission through glass. If your windows don't conform to the above requirements you could be prosecuted. If you are in any doubt whether the windows on your vehicle are lawful, we would suggest you have them checked by a reputable garage.
