pa is just like nj, factory ok, anything else depends on how dark. They are right though.. local shops ussually don't care about tint, the dealer will. I've never heard of anyone getting pulled over for just tint, but some people that have limo tint on front window in the city and stuff get tickets for it after being stopped for other things.
Most southern states and western state come tinted a lil more then they do in the northeast
