tint and the law refer to visible light transmittance or VTL. NYS VTL is 70%
30% tint, coupled with the light tint in the glass, will only allow 25% or so to pass.
My bad, guess I've always confused it.
Don't go crazy and you should be fine. I personally had two vehicles that were already tinted (both bought in SC), which allows for 27% tinting. Mine weren't that dark for South Carolina standards but definitely darker than New York State spec without issue.
