The judge will ask you to plea guilty or not guilty
When I first got to fight a ticket, I heard other people in front of me being asked "plea guilty or not guilty". It is hard for me to decide in a short period of time. Finally I decided to plea not guilty in my turn and fortunately the police did not even show up and my case was then dismissed.
There was another time, I was not that lucky and lost the trial on pleaing not guilty and ended up paying full fine.
So you might want to decide if you will plea not guity (they will ask you then to wait till later to do the trial- either you win or lose) or plea guilty but with explaination (Give them some causes of your speeding. Usually they will reduce your fine.)
That is my own experience.
