The legal limits
Will your film pass in Maine?
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 |

Maine tint law FAQs
What is the darkest legal tint in Maine?
Maine 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 Maine?
A 20% film over factory glass meters about 15.6% VLT. That fails Maine's 35% front-side rule and it is legal on the back-side and rear windows.
Does Maine allow medical exemptions for darker tint?
Yes — Maine allows darker film with a qualifying medical exemption. Keep the exemption paperwork in the vehicle.
Is reflective or mirrored tint legal in Maine?
No — Maine does not allow reflective or mirrored window film.
What is the windshield tint rule in Maine?
Maine allows windshield tint only at the top of the glass: Top 4". Full-windshield film (outside a medical exemption) fails inspection.
