trial by mail
trial by mail
http://www.courtinfo.ca.gov/cgi-bin/forms.cgi
go there and select traffic infractions then print out a tr-205 and fill it out and send it in with your check.
I've never completed the process, but apparently after you send that in theres another form you get or something...basically trial by mail.
I'm doing it for my latest infraction, dunno if it works, but its worth a shot!
worst case you pay the fine, best case...the cop doesnt respond to it and you get your money back.
from what i hear, doing trial by mail is better because the cop doesnt get paid to make a court appearance, so it's an all around inconvenience for him.
also i believe you can do an appeal if you dont like the outcome of the first virdict, via mail as well

...that would be the "trial de novo" form (tr-220)
on my tr-205 i drew a little diagram of what happened and some lame excuse as to why i should be let off the hook. you have a better chance of a cop not responding than of actually convincing the judge that you weren't at fault.
good luck!
