Many (most?) states have very specific limits on the maximum % you can tint the front windows. In our area, they can and will ticket you if the windows are too dark. You have to have a small dated sticker from the installer on your windshield stating the % of tint. I believe the fine is $500. I went with the maximum legal tint. It is lighter than the OEM rear tint. I’m pleased with it. Even at this tint, I’ve noticed that it is sometimes too dark when looking out the front windows at night, such as when turning in the dark.
