Illegal Left Turn

[Jeremiah3017]

My question involves a traffic ticket from the state of: NJ. I was driving North on 4 lane road in a major shopping district and needed to turn left. Normally I am driving south on this same road and I knew there are two entrances into the shopping center when driving South. I was driving carefully, looking for the 2nd entrance, I turned on my turn signal, looked out for traffic, moved into the left lane, and proceeded with caution to turn into the plaza.
After I committed to the turn, I did notice that there was a "t-bone" shaped cement divider and thought it made my turn difficult, but proceeded not giving it a second thought. One block later, a policeman stopped me and issued me a $140 ticket with 3 points. He told me there was no left turn sign, but i did not see it or I would have never made the turn.
I have not had a violation in over 20 years and not a traffic accident in 15 years. Can I contest this violation? I find it a bit extreme.

If you go back and find there is nothing restricting the turn, you have a great defense.

Other than that, just what grounds do you suggest contesting this on?

Thank you for your response. I do plan to revisit the site and take photos as I never saw a sign and it may confusing to other drivers as well. There is no median strip in between the lanes and no traffic light. The 4 lanes are side by side with only the yellow lines dividing the directions. I truly don't know where the sign would be. My goal in contesting the fine is to have the points removed.
