Q: Court Supervision

A: It depends on what is court supervision. As to your particular term or literal meaning of "court supervision," that is not a term used in CA traffic court. Most judicial officers do not want to supervise any traffic case, then want them resolved and closed. Some Orange County judicial officers will hold a case until traffic school is done without requiring a conviction first. However, all Los Angeles County judicial officers require a conviction before granting traffic school so that if the person does not take traffic school then the court can close the case with the conviction. This is because the court does not want to deal with a case longer than necessary.

California DMV communicates with most other states regarding convictions, suspension, license status, etc. For example, if someone gets a conviction for a speeding ticket in another state, then CA DMV will treat that as negligent operator point for CA purposes, a.k.a. a moving violation. Or, if another state has a program like CA traffic school to hold the point confidential from insurance, then CA will probably honor that situation, too.

However, on criminal traffic tickets, the prosecutors and courts have diversion programs in certain situations, where you are on a sort of quasi-probation for a period of time and so long as there are no new violations and all terms are complied with, then the case will be dismissed, meaning no conviction and hence to points on the driving record.
