The legal limits
Will your film pass in Missouri?
A trooper's meter reads the film and the glass. Factory glass runs about 78% VLT, so net VLT = film × glass — which is why "35% film" can fail a 35% state. Common shades over factory glass:
| Film | Meters at | Front side | Back side | Rear |
|---|---|---|---|---|
| 70% | 54.6% VLT | Pass | Pass | Pass |
| 50% | 39.0% VLT | Pass | Pass | Pass |
| 35% | 27.3% VLT | Fail | Pass | Pass |
| 20% | 15.6% VLT | Fail | Pass | Pass |
| 5% | 3.9% VLT | Fail | Pass | Pass |

Missouri tint law FAQs
What is the darkest legal tint in Missouri?
Missouri sets no VLT floor on back-side or rear windows, so film there can be as dark as you like. Front side windows must still meter at least 35% VLT.
Is 20% tint legal in Missouri?
A 20% film over factory glass meters about 15.6% VLT. That fails Missouri's 35% front-side rule and it is legal on the back-side and rear windows.
Does Missouri allow medical exemptions for darker tint?
Yes — Missouri allows darker film with a qualifying medical exemption. Keep the exemption paperwork in the vehicle.
Is reflective or mirrored tint legal in Missouri?
Missouri permits some reflectivity within state limits — check the current administrative code for the exact percentage before installing mirrored film.
What is the windshield tint rule in Missouri?
Missouri allows windshield tint only at the top of the glass: Top AS1 line. Full-windshield film (outside a medical exemption) fails inspection.
