i may be wrong, but if it in fact is registered/tagged/insured in a state that allows that dark of tint, then they can not ticket you....
i mean they can, cause cops do whatever the hell they want..
but legally i think your permitted if they dont know you live here...
i would go to court and fight it....but then again the ticket fine is probably so petty that its not wort taking off a day of work to go to court..
in fact thats why they give out the ticket in the first place....
so thats on you bro, good luck either way...
