The amount of bail is set by a bail schedule in each county. If you fail to appear in court, your bail will be lost and a new warrant will be issued for your arrest. If you cannot post bail, you will be kept in custody. In some cases, instead of paying bail, you could be released on your own recognizance or “O.R.” Your DUI criminal defense lawyer can make a motion for bail reduction or bail review in court. Read more about Bail in California
