I was driving in NJ got pulled over, cop said I was going 56mph in a 40mph which is 16 over and a 4 point ticket. I went back to check the sign and the spot where he hit me with radar was a 45mph zone about 7 blocks later it changes to a 40mph zone the location where he pulled me over was in the 40mph zone but the location on the ticket says the spot where he hit me with radar which was a 45mph zone. The ticket says he got my speed with a radar device. Its my first time getting pulled over and I'm driving for over 7 years. I pleaded not guilty and I have a court date. What should I do?
