Last I checked it's not illegal but the legal limit is something like 15% light blockage. The basic tint or maybe it's discoloration that comes with glass pretty much makes up that 15%. FWIW, I don't think you can buy tint that light so if there's any additional tint, as Mr. Tangas says, it's illegal.

Register your car in Arizona where it's probably legal to tint the windshield.

But I hear you. The worst part of getting dinged on something like this is that you're the one who gets it out of the thousand other violators you see daily -- whether it's window tint, clear corners, no front plate, driving 66mph or whatever. How can you not feel picked on?

What finally stopped bothering me is single drivers in the carpool lane. In the final analysis it's one fewer car in the congested right lanes.
