Depends on the day of the week. If I see a PD cruiser coming up on me from behind, I'll drop my windows and avoid the grief if possible. IF they pull you over (which can and at some point will), the fine is about $25.00 which you have to pay the courts..but you are also forced to remove the tint and go to a CHP location to have them inspect and sign it off. So it's not the $, its the hassle really. I think the fine goes up if you get a 2nd one in a specific window of time (like 90 days..but I don't recall exactly).
So basically just be ready lower your windows at a moments notice. My wife's car had tint and lasted 5yrs before she got pulled over. Mine has been tinted 18mos and so far, so good.
