Legal window tint in Ireland

What is the legal window tint in Ireland? It has very specific laws, and In Republic of Ireland you can have the following window tint darkness:

  • Windshield: must have a minimum of 65% VLT
  • Front side windows: must have a minimum of 65% VLT
  • Back side windows: any darkness can be used
  • Rear window: any darkness can be used

VLT means Visible Light Transmission, and this number represents the percentage of light able to pass through your car windows.

65% VLT window tint allows 65% of total light to pass through, and blocks 35% of visible light. See examples of different tint darkness!

NCT inspection

Window tint is part of NCT (National Car Test) testing in Ireland. If you install window tint which is not legally permitted your vehicle will fail inspection.

Window tint is tested with a device called a light meter or photometer, and you should know that police officers in Ireland are also equipped with these devices with increasing frequency.

Road Safety Authority allows up to 3% variance in window tint levels, however due to light meters not being 100% accurate we do not recommend tinting windows beyond legal limits.

Ireland does not allow medical exemptions for darker window tint.
