Pennsylvania Window Tint Laws
Pennsylvania holds sedans to 70% on every window — among the strictest in the nation — and checks it at annual inspection. High-clarity ceramic film is the only way to get real heat rejection and still pass.

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 "70%" 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.
