Is 15% Window Tint Legal in Finland After the 2026 Regulatory Updates?

No. 15% window tint violates Finland’s 2023 Road Traffic Act amendments enforced by Liikenne- ja viestintävirasto (Traficom), which mandate ≥70% light transmittance for front side windows. Non-compliance risks fines up to €120 and mandatory removal.

Key Regulations for 15% Window Tint in Finland

  • Light transmittance threshold: Front side windows must allow ≥70% of visible light (VLT), per Traficom’s 2023 technical directive (LVM/1085/01.04.05.00/2023).
  • Medical exemptions: Only valid with prior approval from Traficom, requiring documented proof of a condition necessitating darker tint (e.g., photodermatitis), reviewed case-by-case.
  • Enforcement protocol: Police conduct spot checks using certified luxmeters; vehicles failing tests are issued immediate removal orders, with repeat offenses escalating to vehicle impoundment under the 2024 Police Act amendments.
