PA drivers in NJ do not get points and isnt a 'transferrable penalty' state. nj on the otherhand is. which means whatever you do in pa will reflect as if you were driving in nj and the punishment is just as if you did it in nj.

you might want to contact local law enforcement before the court date and as a measure of ''discovery'' for the court date you want to see the ticketing officers credentials regarding his radar gun operations/calibration and there should be some type of documents as to when the last time his radar gun was calibrated. if they fail to have their documents in order you might just catch them sleeping
