Trenton City Police set the speed trap up just inside the Trenton City line boundary between Ewing Township and Trenton City on Rt31 South(Pennington Ave). As you travel southward out of Ewing at 35mph on Parkside Ave, you come to a complete stop at the intersection of parkside Ave and Rt 31 south. As you look back and forth at the North and South bound traffic flow and are attempting to negotiate the turn into the southbound flow, immediately on your right hand side is a LOWER POSTED SPEED of 25mph which can easily not be observed due to your focus on entering the southbound traffic flow safely. You then unwittingly start accelerating back to your last speed of 35mph and the moment you exceed 25mph, the radar locks in on the pre-planned speed. The Mayor of Trenton, Commissioner, Chief of Police and Court Judges all supoport this despicable type of trap but all other speed traps more for the resultant revenue generated than for any "officially" touted "safety" concerns.
