Missouri: Everything You Need to Know

• Missouri Window Tint Exemption Laws

  Missouri's medical window tint exemption is authorized under RSMo Section 307.173 and administrative rule 11 CSR 30-7.010. The Missouri State Highway Patrol issues permits allowing drivers with serious medical conditions to have darker tint on front side windows.

  • The exemption allows window tint darker than the standard 35% VLT on front side windows.

  • Permits require a physician's prescription specifying your medical condition and required tint percentage.

  • The prescription must be issued within one (1) year of your permit application.

  • Permits allow vehicle operation by the titleholder and relatives within the second degree residing in the household.

  • Permits are vehicle-specific. Each vehicle requires its own permit, though one prescription covers multiple vehicles.

  • When the permit is issued, you receive a windshield sticker and rear decal for law enforcement verification.

  • The permit must be carried in your vehicle at all times.

  • Violations without a valid permit are a Class C misdemeanor with fines up to $75.

• Legal Tint Limits

  Missouri law sets specific limits on how dark your vehicle windows can be tinted. With an approved medical permit, your darker window tint becomes legally recognized.

  Standard Missouri Tint Limits (Without Exemption):

  • Windshield: Non-reflective tint permitted only above the AS-1 line.

  • Front Side Windows: Must allow more than 35% of visible light (35% VLT). 3% variance allowed.

  • Back Side Windows: Any darkness permitted.

  • Rear Window: Any darkness permitted.

  • Reflectivity: No metallic or mirrored appearance allowed.

  • Mirrors: Dual side mirrors required if back window is tinted.

  With a Medical Permit:

  • Front side windows may have less than 35% VLT as specified in your physician's prescription.

  • The exact tint percentage is determined by your physician based on your medical condition.

  • Your permit, windshield sticker, and rear decal provide verification during traffic stops.
