According to the New Jersey Statutes Annotated (NJSA) points list, 23 miles per hour over the speed limit is assigned 4 points. Once you plead guilty and pay your fine for this moving violation these points, along with the conviction for the offense, will be placed on your NJ driving record by the Motor Vehicle Commission (MVC).
Although the MVC keeps a permanent record of all the points you have earned, it is possible to earn point deductions by remaining violation and suspension-free for one year or by taking qualified driving courses approved by MVC.
To find out the cost of the speeding citation you received, I would suggest contacting the clerk of the court whose number is usually found somewhere on the face or backside of the ticket. You may also try to determine the cost of the violation online by going through the New Jersey Municipal Courts website.
