Is 15% Window Tint Legal in Thailand After the 2026 Policy Reforms?

No. Thailand’s Road Safety Act B.E. 2522 (1979) and Ministerial Regulation (No. 12) B.E. 2566 (2023) prohibit window tints below 30% VLT for front windshields and side windows, making 15% illegal. Police enforce this via roadside checks, with fines up to 5,000 THB and potential vehicle impoundment. Recent 2026 compliance directives prioritize road visibility for safety.
