New Hampshire Window Tint Laws

Live Free or Die — except on front windows, where New Hampshire allows no aftermarket tint at all. Back sides and rear hold at 35%, and a medical waiver is the only path to darker fronts.

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.

New Hampshire tint FAQ

What is the darkest legal tint in New Hampshire?+
New Hampshire does not allow aftermarket tint on front side windows. Behind the driver, film must allow at least 35% of light through.
Can I tint my windshield in New Hampshire?+
Tint allowed on the top 6 inches.
Does New Hampshire allow medical exemptions for darker tint?+
Yes. New Hampshire 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 New Hampshire?+
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.
