Sonoma County Traffic School

Sonoma County reaches from Petaluma, by the Marin County line, north past Cloverdale, and from the Pacific east to Napa County. US 101 is its spine, through Petaluma, Cotati, Rohnert Park, Santa Rosa, Windsor, Healdsburg and Cloverdale. State Route 116 follows the Russian River in from the coast to Guerneville, then turns inland through Sebastopol to Cotati. State Route 1 hugs the shore from Bodega Bay to Sea Ranch, and State Route 128 crosses the north toward Calistoga. The Census Bureau counts 486,444 residents in nine incorporated cities and towns.

The California Office of Traffic Safety counted 2,438 people killed or injured in Sonoma County crashes in 2023, placing the county 26th of 58, where 1st is the worst record. Two groups rank worse than the county as a whole. Motorcycle crashes killed or injured 137 people, 17th in California, and 94 bicyclists were killed or injured, 18th.

Every location Sonoma County Superior Court lists is in Santa Rosa. It names one place for adult traffic, the Traffic Division at the Hall of Justice, 625 Administration Drive, so a ticket from Cloverdale or Petaluma ends up there too. The court announced that its traffic clerk's office would open in this new building on July 20, 2026. Court letters printed before the move give the Hall of Justice as 600 Administration Drive, and three traffic school websites we checked still do. Mail and visits go to 625. The California Highway Patrol's Santa Rosa Area serves most of the county and its Marin and Napa Areas cover some roads, so a CHP ticket lands at the same Traffic Division as one from a city police officer.

The DMV's court code list gives this court three Santa Rosa codes: 49460 labelled traffic, 49200 labelled juvenile, and 49100, which carries only the court's name. Enroll with the court and code on your citation or court paperwork. Drivers under 18 do not go to the Juvenile Justice Center on Rancho Los Guilicos Road, whose page lists only delinquency and dependency cases. Juvenile Traffic works from the Hall of Justice at (707) 521-6681, and a parent or legal guardian must come to any required appearance.

The court mails a Reminder Notice to the address on your citation. If none arrives, call the Traffic Division at (707) 521-6680. To elect traffic school, you pay the court the total due with traffic school on that notice, which includes a non-refundable administrative fee. The court then mails the traffic school forms and a copy of the DMV's list of licensed schools.

The court's traffic page says it puts no case information online, so to check on a case, call the Traffic Division or research it in person at the Hall of Justice.
