Sonoma County stretches from the North Bay communities of Petaluma and Santa Rosa to the coast and wine country, with US-101 serving as the primary enforcement corridor for the CHP Santa Rosa area command. Visitors and residents traveling SR-12 through the Sonoma Valley and SR-116 toward the coast are also common citation locations. The courthouse in Santa Rosa accepts TBWD filings by mail.
TicketClear prepares your TBWD documents. You file directly with the court.
Sonoma County has no active automated camera enforcement program as of 2025. All traffic citations here are issued by sworn officers in person.
Officer-issued red light and speeding tickets are still eligible for Trial by Written Declaration.
