Missouri Window Tint Laws
Missouri window tint laws: front, rear, and windshield VLT limits, reflectivity rules, medical exemptions, and fines.
Missouri window tint law sets the darkest film you may apply to each window. The numbers are visible light transmittance (VLT) — lower means darker.
| Window | Allowed tint | Note |
|---|---|---|
| Front side windows | 70% VLT (minimum) | Driver & front passenger |
| Rear side windows | Any darkness allowed | Behind driver |
| Rear window | Any darkness allowed | Back windshield |
| Windshield | top 5 inches (AS-1 line) | Only a non-reflective strip at top |
Reflectivity
Reflective film is capped at 35% reflectivity.
Windshield rules
Missouri allows tint only on the top portion of the windshield (top 5 inches (AS-1 line)). The rest of the windshield must stay clear.
Medical exemption
A medical exemption is available — a licensed physician’s note can let you apply darker film than the standard limit.
Penalties
A citation can cost $75. Officers may stop you for illegal tint (primary enforcement in most states).
