15 receives a speeding ticket while driving on his white slip

Your son did the act, and your son got the ticket. You must appear in court with him if he is to receive court supervision (which is exceedingly important in his case) - in addition, if given supervision, State law requires he attend traffic safety school. Given the circumstances, I hesitate to tell you directly what to do, because it is important to know how Judges and prosecutors will react to such situations in your area, and I do not regularly appear in the Courts near Effingham. You should speak to an attorney who deals with traffic defense on a regular basis in the Court where your son's case will be heard immediately. Waiting too long can limit your options and may restrict what the attorney can do to help. Good luck.
