The DMV Hearing

The DMV hearing is one of the most important events after arrest or citation for an alcohol related driving offense. You must act quickly to obtain a hearing. In most instances, you only have 10 days from the date of arrest or detention to request a hearing. Contact us to find out why the DMV hearing plays a much larger role in your case than you may think. We can share with you how DMV hearings have helped us win the cases in court.
