No, Missouri law caps front-side window tint at 35% light transmittance, rendering 50% non-compliant. The state’s 2026 compliance framework, enforced by the Missouri State Highway Patrol, mandates strict adherence to VLT standards to mitigate visibility risks. Violations may trigger citations or mandatory tint removal orders.
Key Regulations for 50% Window Tint in Missouri
- Front-side windows: Must allow ≥35% visible light transmittance (VLT), measured via photometric devices. 50% exceeds this threshold, violating §307.173 RSMo.
- Back-side and rear windows: Permit any darkness level if the vehicle has dual side mirrors, but local ordinances (e.g., St. Louis County) may impose stricter rules.
- Medical exemptions: Require a physician’s certification submitted to the Missouri Department of Revenue, valid for up to 3 years. Standard 50% tint does not qualify.
Local enforcement varies; Kansas City and Springfield police departments prioritize roadside VLT checks during summer months. Non-compliant vehicles face fines up to $214.50 under municipal codes. The 2026 update to §307.173 aligns Missouri with updated ANSI safety standards, closing loopholes for aftermarket tint installations.
