1st speeding ticket

[blkmz3]

My first one last night coming off betsy ross bridge. It was 3am no one on the road pitch dark and he was sitting right after the overpass. Cop got me with some rear view radar DP-55 or something at 80mph. I definitely was not going 80mph. There was a truck in front going real fast but he sees my car with exhaust and stops me instead. I was very polite the cop was nice and all but still gave me a ticket. He told me to go to court when I asked if I can do anything about it. Does anyone know how they deal with first offenders and if new jersey has a thing called "under acceptance" where you cant get a violation for a year and it will disappear. my friend also told me there are ridiculous surcharges if you want to drop your points and pay the fines. this is my first traffic violation been driving for 5 years clean record till now. Sarge any suggestions?
