Legal Question in DUI Law in California

He faces a new second DUI, which is a misdemeanor and carries up to a year in county jail. He also faces a violation of probation for his first DUI as well as the hit and run. The first DUI carries up to 6 months in county jail and the hit and run (assuming it was a misdemeanor and nobody was hurt) carries up to another six months. In total, his maximum is around 2 years (more if they tack on things like driving on a suspended license, which I'm almost certain they will, as I don't think with these issues your son's license was valid at the time of the newest case).

The statutory minimum is 96 hours in custody, but given that he faces 3 driving crimes, two of which are DUIs in close proximity, I think his plea offer is going to be substantially higher than the minimum. Without knowing the particular judge he faces and any other facts of the case(s), I can only venture a guess that he's looking at several months in custody unless they are willing to offer him a live-in residential alcohol treatment program in lieu of jail.
