Is 15% Window Tint Legal in Ireland After the 2026 Law Changes?

No, 15% window tint is illegal in Ireland under current Road Traffic Regulations. The Road Safety Authority (RSA) enforces VLT (Visible Light Transmission) standards of ≥70% for front side windows and ≥60% for rear windows, with no exemptions for medical or other claims. Non-compliance risks fixed charge notices (€60) or court convictions, effective since 2023.

Key Regulations for 15% Window Tint in Ireland

  • Visible Light Transmission (VLT) Limits: Front side windows must allow ≥70% light transmission; rear windows ≥60%. 15% tint fails both thresholds.
  • Enforcement by RSA & An Garda Síochána: Gardaí conduct roadside checks using light transmission meters. Vehicles failing tests face immediate penalties.
  • 2026 Compliance Shift: New EU vehicle type-approval rules (UNECE R43) will standardize VLT testing, eliminating loopholes for aftermarket tints.

Irish law prioritizes driver visibility and road safety, with no grandfather clauses for pre-existing tints. Medical exemptions require RSA approval, but 15% tint exceeds even these rare exceptions. Always verify VLT compliance before installation or purchase.
