Yes, California DMV Administrative Hearings can be won.. We have a great deal of experience defending and winning California DMV Administrative Hearings. In order to restrict your California driving privilege, the DMV Hearing Officer must make three determinations: Who was driving the vehicle, whether the police officer had "reasonable cause" to pull over and arrest the driver (a complicated legal question), and whether the driver had a blood alcohol concentration of .08 or above (which is open to many challenges). A vigorous and knowledgeable defense, possibly including expert witnesses, can raise serious questions about one or more of these criteria.
