It is true that judges give more weight to an officer's testimony as a rule. But if he testifies truthfully then it may be hard for him to prove the case. In order to be convicted of failing to yield to a pedestrian, the law requires that there either be a pedestrian in the crosswalk, or on the adjacent curb with the legal ability to cross the street (i.e. a walk signal). It is unlikely, however, that this charge would get thrown out on a technicality. Judges are not particularly concerned with that. The purpose of a citation
is to notify you of the charge. If it does that, the rest of it is not of much concern. The officer can testify about what happened so it is of little consequence if there is a typo or something on the ticket.
If you are talking about the public defender you may want to check with the county office if you are even eligible. The PD's office in most counties do not represent individuals on a traffic case where there is no possibility of incarceration. So you may end up having to handle this yourself.
Judges do not appreciate repeated delays that have no legitimate basis. They have busy dockets and will generally only grant postponements for good cause and don't tend to have patience for pointless delays. So you may not be helping your cause that much by asking for postponements without cause, particularly if you ask for one and the judge denies it and you are stuck with that judge.
The rules of discovery don't apply to traffic infractions
. That said, some judges may allow you to request very limited discovery. However, discovery has to be done before the court date. One does not get to conduct discovery in court, although you can ask to see the officer's notes he refers to them to refresh his recollection during trial.
In a case like this, the maximum penalty is a fine
only. So a plea bargain typically involves a fine. They may undercut the original fine as an incentive to plead guilty, but not always. They may also offer an ACD (adjournment in contemplation of dismissal) where the ticket is postponed a few months and if you don't get further tickets in that time, the case is dismissed. You are more likely to get a lower fine or ACD if you have a relatively clean record.
