my car is with
100% tint on rear screen
100% tint on quarter windows in rear
50% tint on rear door windows
25% tint on front door windows
100% strip on upper front screen
No problems yet but the police can stop and give ticket.
I once asked a traffic police warden, if it is illegal, he said that it is, but they dont care to catch tinted glasses, until the other police force does for security concerns, and max they will do is take you to police station for some fast-money.
