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.

Washington, D.C. tint FAQ

Can I tint my windshield in Washington, D.C.?+

No tint below the AS-1 line.

Does Washington, D.C. allow medical exemptions for darker tint?+

Yes. Washington, D.C. 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 Washington, D.C.?+

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 — especially in stricter states like Washington, D.C., where a light ceramic film delivers real heat rejection at a legal 70%+ VLT.
