The Napa County DUI Program runs programs for drivers who have been convicted of driving under the influence of alcohol. These programs are mandated. Programming includes educational courses and counseling. Specific programs are assigned dependent on whether it is a first-time offense by the courts. Multiple offenders must enroll in an 18-month program. Rates and schedules for these programs are available on the DUI program website. For further inquiries, phone the Napa County DUI Program.
