Window tint levels in NY state are limited to a minimum of 70% light transmittance. I do not believe this is the most restrictive requirement but new england isn't as sunny as Arizona or Florida. https://drivinglaws.aaa.com/tag/glass-window-tinting/
People now buy packages where you pay annually and the tinting people will remove your tint, inspect your car, and then re-tint the car on the same day!
