Fighting Your Sonoma Traffic Ticket
Trial by Written Declaration
The most effective way to fight your Sonoma traffic ticket without taking time off work is through a Trial by Written Declaration. Request form TR-205 from the court or download it online. Submit your written defense along with the bail amount (which gets refunded if you win) before your due date.
Even if you lose, you have a safety net: within 20 days of the verdict, you can request a trial de novo for an in-person hearing—a second chance to present your case.
In-Person Court Appearance
You can appear in person at your scheduled court date at the Hall of Justice, but consider what that requires: taking time off work during business hours, traveling to the courthouse, and potentially waiting hours for your case to be called. For most people, the written declaration approach is far more practical.
