I have mine in my lower passenger side windshield and I pass state troopers almost everyday going back and forth to work and I have never had a problem...I will have had my truck 2 years in August...
PS: As I leave to go to the 'rents house tonight...I will probably get pulled over and ticketed
PSS: Awhile back I think I remember the corvette guys petitioning to do away with the front plate here in Tx... guess that never panned out.
