I have done 20% on my front side windows for the last 20 years in NY state and have never been bothered by the cops for it. However, NYS inspection is a whole new problem. Since 2019, they require the light transmission reading be entered into the system so I have had to pull off the tint each year for inspection. What a PITA.I want the dark in the back to block the sun from going in the kid and babys eyes, it always bothers them on road trips. The law in my great state of NY is 70% visible light transmission on front windows. So basically any shade of tint up front is illegal. If I'm darker in the back and lighter up front maybe they won't pull me over.
