Pretrial diversion, generally speaking, is a county-by-county program. It is offered at your first appearance in court and has a number of probationary requirements. In matters such as yours, there are a number state and local laws that provide for similar disposition (delayed sentencing, advisement pleas, HYTA status, etc). the person who would be best acquainted with such a program is a local defense lawyer or the prosecutor. If you have already plead, it is probably too late. Open container cases will only make a difference if you have other alcohol-related convictions. I hope this helps.
