Is 35% Window Tint Legal in Vietnam After the 2026 Policy Reforms?

No. 35% window tint is illegal in Vietnam under Ministry of Transport (MOT) regulations, which cap front-side windows at 30% VLT. Rear windows may have darker tints, but front windows must allow ≥70% light transmission. Non-compliance risks fines up to ₫8 million (2023 MOT Circular 31/2023/TT-BGTVT).

Key Regulations for 35% Window Tint in Vietnam

  • Front-side windows (driver/passenger): Must have ≥30% visible light transmission (VLT); 35% violates this.
  • Front windshield: Must be fully transparent (no tint allowed per MOT Circular 31).
  • Rear windows: May exceed 30% VLT, but reflective tints or metallic films are prohibited under QCVN 13:2018/BGTVT standards.

Enforcement is strict in major cities (Hanoi, Ho Chi Minh City) via traffic police checks. Vehicles imported post-2026 must comply with updated VLT standards under draft amendments to QCVN 13, tightening rear-window tolerances. Always verify local police interpretations, as interpretations vary by province.
