they are hassling you over a 5% rear window? in the PA code it doesnt say anything about having tint on the rear window… so it will just get thrown out
just cant have it on the windsheild, side window or rear wing (like on a truck)
anything behind your head is legal. I been to court and it was thrown out.
I never get bothered by whitehall, let again my uncle is the public works supervisor so i bet that helps a little
