Hearings and Trials: No Contest in a Trial by Written Declaration

My question involves a traffic ticket from the state of: California

I allegedly ran a stop sign last Jan. Trial by written declaration is set for next week. I eventually got discovery from the CHP and it's damning. Should I plead no contest in the TBD to maximize my chance of getting traffic school? I don't want my insurance to go up.

Thanks in advance
