Tinted vehicle windows: the law

Vehicles first used on 1 April 1985 or later

The front windscreen must let at least 75% of light through and the front side windows must let at least 70% of light through. There are no rules for tinting the rear windscreen or rear passenger windows. If your front windows are factory tinted, this may have an impact on adding any further tint.

Penalties for having wrongly tinted windows:

If your windscreen or front side windows are tinted too much you could get:

• a ‘prohibition notice’ stopping you using your vehicle on the road until you have the extra tint removed
• a penalty notice or court summons

This applies to any vehicle on the road. However, if this is for track or show only, and will not be on the road, we can apply darker tints.
