I believe that's true from what I've seen people say. Depends on the inspector I guess. Anything not "right" with the car can cause it not to pass inspection.
NYS has a pretty strict tint restriction it is 75% which is basically nothing. And yes some shops are starting to impliment the policy with inspections.
I had 5% for a while but i kept getting tickets and the first was $50 and it went up $100 each time. I sold the car but i got one for $250 and it wasnt worth it.
