Is 35% Window Tint Legal in Taiwan After the 2026 Framework Overhaul?

No. Taiwan’s Road Traffic Management and Penalty Points Act prohibits window tinting below 70% visible light transmittance (VLT) for front windshields and side windows. A 35% tint exceeds this limit, rendering it illegal and subject to fines up to NT$3,600 under Article 31 of the Act. The Ministry of Transportation and Communications (MOTC) enforces these rules, with local police conducting random inspections, particularly in Taipei and Kaohsiung.


Key Regulations for 35% Window Tint in Taiwan

  • Visible Light Transmittance (VLT) Threshold: Front windshields and front side windows must maintain ≥70% VLT; rear windows may have darker tints but must not obstruct driver visibility. A 35% tint falls below the 70% requirement for front windows.
  • Enforcement by Local Authorities: Police departments in major cities (e.g., Taipei City Police Department, Kaohsiung Police Bureau) conduct roadside checks using portable VLT meters. Vehicles failing inspections face immediate fines and mandatory tint removal.
  • 2026 Compliance Shifts: The MOTC is piloting stricter enforcement tools, including AI-powered license plate recognition linked to tint databases, to curb violations. Owners of non-compliant vehicles must rectify tints before renewal of annual inspections.
