The legal limits
Will your film pass in Louisiana?
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 | Fail | Pass | Pass |
| 35% | 27.3% VLT | Fail | Pass | Pass |
| 20% | 15.6% VLT | Fail | Fail | Pass |
| 5% | 3.9% VLT | Fail | Fail | Fail |

Louisiana tint law FAQs
What is the darkest legal tint in Louisiana?
Front side windows must let through at least 40% of light, back side 25%, and the rear window 12%. Anything darker fails a meter check.
Is 20% tint legal in Louisiana?
A 20% film over factory glass meters about 15.6% VLT. That fails Louisiana's 40% front-side rule and it also fails the back-side limit (25% vlt min).
Does Louisiana allow medical exemptions for darker tint?
Yes — Louisiana allows darker film with a qualifying medical exemption. The state also requires a compliance sticker between the film and glass, so carry the exemption paperwork with the vehicle.
Is reflective or mirrored tint legal in Louisiana?
Louisiana 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 Louisiana?
Louisiana allows windshield tint only at the top of the glass: Top AS1 line. Full-windshield film (outside a medical exemption) fails inspection.
