Basically depends where you live..
Mine are darker than that, but I was pulled over monthly for them when I lived in alaska.. I lived in a small town that was outside of a larger town, so lots of cops lived there. It was a nicer area so there was minimal crime. That meant cops nitpicked all the little stuff, tinted tails/ windows, etc.
Anyway, drove 5000 miles across Canada and the US, and now have been in florida for about 6 months with 0 issues, and i've also added 15% window tint down here.
