When I lived in FL I had 5% all around and double 5% on the rear glass.
When I moved back to La. and had my truck registered here I never changed the tint. I was on my way to a Drs. appt. one morning on a 4 lane highway. I saw a State Trooper traveling opposite of me, made a U-turn, and pulled me over. He gave me a ticket for $193.50, which a friend had fixed for me. But, I did get the front windows with legal tint, 35%. When someone is behind me their headlights look like candles in my rear view mirror.
