Who Writes the Tickets in Sonoma County
The Sonoma County Sheriff's Office and the agencies that report for Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sonoma and three more cities write the traffic tickets in Sonoma County.
The FBI's agency list also places three state agencies, two campus police departments, one other agency and one state police unit in Sonoma County (the arrest records guide names each one); the Highway Patrol's Santa Rosa Area Office writes the tickets on the state highways.
The Driving Record and the California Department of Motor Vehicles
Convictions are reported by the court to the California Department of Motor Vehicles, which keeps the driving record and decides on points and suspensions. Order the driving record from that agency, not from the court.
Paying a ticket is a conviction, reported to the California Department of Motor Vehicles like any other; contesting it means a plea of not guilty entered with the court by the date on the ticket.
A DUI is a criminal charge rather than a ticket, with its own license case before the DMV (see Sonoma County DUI).
