Irish tint law
What tint is legal in Ireland?
Short version: your windscreen must let through at least 65% of light, your front side windows at least 50%, and everything behind the driver can be as dark as you like. Here is the detail, what the NCT looks for, and where people get caught out.
65%
Minimum light through the windscreen
50%
Minimum light through front side windows
No limit
Rear doors, quarter glass and rear screen
What the law actually says
Windscreen
65% light must pass through
Front side windows
50% light must pass through
Rear side windows
No light transmission limit
Rear screen
No light transmission limit
Light transmission is measured through the glass and the film together. Most modern glass is already slightly tinted from the factory, so a film sold as "50%" can put the finished window under the limit. That is why we measure before we recommend a shade.
Frequently asked questions
- 01What is the legal tint limit in Ireland?
- Under the Road Traffic (Construction, Equipment and Use of Vehicles) Regulations, the windscreen must transmit at least 65% of light and the front side windows at least 50%. Windows behind the driver — rear doors, quarter glass and the rear screen — have no light transmission limit for passenger cars.
- 02Will tinted windows fail the NCT?
- Tint on the windscreen or front side windows that falls below the legal transmission levels is a failure item, as is any film that is bubbled, torn or obstructing vision. Legal rear tint on its own does not fail an NCT.
- 03Can the Gardaí stop you for tinted windows?
- Yes. Gardaí can stop a vehicle and check front glass transmission with a meter, and non-compliant front tint can lead to a fixed charge notice and a requirement to remove the film. Rear tint is not an offence.
- 04Does window tint affect car insurance in Ireland?
- Legal tint fitted professionally is not usually treated as a modification that needs declaring, but insurers differ. If your policy asks you to declare modifications, a quick call to your broker settles it. Illegal front tint can give an insurer grounds to argue about a claim.
- 05Is 65% tint legal in Ireland?
- A 65% VLT film means 65% of light passes through. That meets the windscreen requirement, so it is the shade most commonly used for legal windscreen and front-window work in Ireland. Anything darker than 50% VLT on the front sides is outside the limit.
- 06Do factory privacy glass cars count?
- Many SUVs and vans leave the factory with dark privacy glass in the rear. That is legal because the restriction only applies forward of the driver — and it is also why matching front film has to be much lighter than the rear.
