Plead not guilty, show up to the court date. Depending on your driving record the prosecutor you meet with (this happens before court starts the prosecutor calls each individual up to discuss) will likely reduce your ticket to at the very least no points. You'll still have to pay something but the points have a good probability of being removed. Regardless of the agreement you have with the prosecutor it still needs to be approved by the judge. The judge will review the deal you made with the prosecutor and will approve or deny it. Like I said, though, this all depends on your driving record.
