Q403: How dark can I tint the windows on my vehicle?
In the front windscreen and front side windows of motor vehicles first used after 1st April 1985 there must be a minimum of 75% of light allowed through the window (for vehicles first used before 1/04/85 min of 70%).
The windows that are exempted from this are the rear windscreen and the rear side windows on both sides.
Failure to abide by this means that you commit an offence and could be liable for a fine. Make sure the tints are checked by a professional.
