Window tint law guides
Plain-English explainers on the concepts behind U.S. window tint laws. Every guide is cross-linked to the state pages it mentions and cites its primary sources at the bottom. Use these to understand the why, then use the state index for the what.
Fundamentals — 14 guides
VLT (Visible Light Transmission) explained
VLT (Visible Light Transmission) is the unit every U.S. window tint law uses. Learn exactly what VLT measures, how police tint meters work, why film-rated VLT differs from installed VLT, and how to stay legal in every state.
Window tint percentages explained
Every window tint percentage from 90% to 5% explained visually: how dark it looks, how much light it lets in, heat and UV performance, and which U.S. states allow each percentage on which windows.
Windshield tint laws & the AS-1 line
U.S. windshield tint laws are stricter than side-window rules. This guide explains the AS-1 line, state top-strip allowances, clear ceramic windshield films, and how each state writes its windshield rule.
SUV vs sedan window tint laws
Most U.S. states allow darker tint on back windows of SUVs, vans, and pickups than on sedans. This guide explains the federal MPV classification, how to confirm your vehicle type, and every state where the rule splits.
How to measure window tint VLT
A step-by-step guide to measuring window tint VLT the same way law enforcement does: which meter to use, how to calibrate, how to account for factory glass, and the common mistakes that produce wrong readings.
Window tint reflectivity laws
Reflectivity is the second rule every tint law uses and the one most drivers miss. Learn what tint reflectivity means, how it is measured, and which states cap it at 20%, 25%, or 35%.
Factory tint vs aftermarket window tint
Factory privacy glass and aftermarket window film are regulated differently in every U.S. state. Learn why factory tint is almost always legal, how the law treats film layered on top, and when combining the two gets you ticketed.
Windshield "eyebrow" tint — the visor strip
The "eyebrow" or "visor strip" at the top of the windshield is regulated differently than the rest of the glass. Learn what depth is legal, why it must be non-reflective, and how it differs by state.
Why factory privacy glass is legal in every state
Factory privacy glass on SUVs and vans is darker than state VLT minimums but is perfectly legal everywhere. Here is why — the federal certification rule that makes it so.
Tint percentages visual comparison
What each window tint percentage actually looks like, how much you can see through it, and how nighttime visibility changes. A quick visual reference for picking a VLT.
How to tell factory tint from aftermarket film
Four quick visual tests to tell if a window has factory privacy glass or aftermarket film applied on top. Useful for buyers, inspectors, and anyone contesting a tint citation.
