Quoting
GWE
This is an infraction -- there is no police report--- there might be a tape from the police car or a radar printout. When you show up at your arraignment you can then ask the DA for discovery. I have no idea how this works in Orange County. The DA or City attorney might not staff the court. You may have to ask the police agency directly.
You will have to plead not guilty and set the case for trial to get discovery.
What agency issued the ticket?
I think the fine will be less than $300, -- you may be able to get that reduced if you show up at Court.
See what the fine is on the courtesy notice you get. If you have no other problems you should consider going to traffic school.
