What VLT means (and how police check it)

VLT — Visible Light Transmission — is the percentage of outside light that makes it through your glass. The number printed in the law is a floor: film may be that bright or brighter. Because factory glass already blocks a little light, an officer's meter reads the combineddarkness of glass plus film. A film sold as "35%" on top of factory glass can meter a few points darker — which is why professional installers measure the final result, not the box label.

Quality matters as much as darkness. Dyed films fade purple and bubble; ceramic films like ULTRASHIELD SHADOW reject heat and up to 99% of UV at any legal darkness, with no signal interference — so you get the comfort without gambling on the number.

Maine tint FAQ

What is the darkest legal tint in Maine?+
On front side windows, film must let at least 35% of light through (35% VLT). Behind the driver, any darkness is legal.
Can I tint my windshield in Maine?+
Tint allowed on the top 5 inches.
Does Maine allow medical exemptions for darker tint?+
Yes. Maine allows darker-than-standard tint with qualifying medical documentation. Keep the paperwork in the vehicle — officers can ask for it during a stop.
Is ceramic tint legal in Maine?+
Yes — the law regulates darkness (VLT) and reflectivity, not film technology. A ceramic film at a legal VLT is fully compliant, and it rejects far more heat than dyed film at the same darkness, which is why installers recommend it.
Are mirrored or reflective films legal in Maine?+
Maine restricts reflectivity: Non-reflective film only.
