22450. (a) The driver of any vehicle approaching a stop sign at the
entrance to, or within, an intersection shall stop at a limit line,
if marked, otherwise before entering the crosswalk on the near side
of the intersection.
If there is no limit line or crosswalk, the driver shall stop at
the entrance to the intersecting roadway.
If there is no stop sign or signal, there is no requirement to stop. If there is a sign or signal, and no limit line or crosswalk, the stop must be made at the entrance to the intersecting roadway. This could be an extended curb line (not painted) or the intersecting line defined as the extended pavement edge of the intersecting roadway.
If there are no stop signs present, take pictures of the intersection or get google images online of the intersection. These should go well with your TR205 Form, Trial by Written Declaration. If the officer doesn't respond or if you are found guilty at this stage, you can go back into court with the officer's written TBD statement, made under oath. When you show this statement to the judge with pictures showing no stop sign is present, you should be acquitted, unless the judge is corrupt.
