Window Tint Laws
by State to All 50 States

No, and this is where most people get confused. Front side windows are always the most restricted. Rear side windows and rear windows usually have more lenient rules, and some states allow any darkness on rear windows as long as the car has working rear-view mirrors. The windshield only allows a non-reflective strip at the top in every state. Always check the rules for each window position separately, not just the overall limit.

Yes. If you move from Texas to California with 25% front tint, your windows are now illegal even though they were perfectly legal where you bought the car. Enforcement varies by state but if you register your car in a new state with stricter tint laws you should expect to replace the front window film to avoid fix-it tickets and potential inspection failures.

Yes. Most state laws measure the total VLT of the combined glass and film. If your rear factory glass already has 20% VLT and you add a 35% VLT film on top of it, the combined result is around 7%, which is likely illegal. Always ask your tint shop to measure the existing glass VLT before recommending a film shade for rear windows.

Law enforcement officers use a device called a tint meter or photometer. It clips onto the window and measures the percentage of light passing through. The device gives an immediate reading of the VLT percentage. If the reading is below your state's legal minimum for that window, you will receive a citation. Reputable tint shops test their work with the same devices before you leave.
