Can I tint my car’s front and rear windows?
There are different rules for the front and rear car window tints and it also depends on when a vehicle first came into use.
The Law says:
You MUST NOT use a vehicle with excessively dark tinting applied to the windscreen, or to the glass in any front window to either side of the driver. Window tinting applied during manufacture complies with the Visual Light Transmittance (VLT) standards. There are no VLT limits for rear windscreens or rear passenger windows.
Road Traffic Act 1988 Section 42
Road Vehicles (Construction and Use) Regulations 1986 regulation 32
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
