The small town cops (actually ticket writers) of Lawrence Twp. like to clock speeders on Rt 21 between Rt 93 and Butterbridge road. At night look out, they illegally turn all of their lights out and park parallel with Rt 21 making them hard to see until you get up on them in their car and wait for you unsuspectingly to cruise down Rt 21 going a few miles over the speed limit. Please look out for their "Ambush" style tactics, and don�t fall victim to the Lawrence Twp police department. They seem to really get off on writing tickets, it seems to be some kind of power trip for them.
