If you hire an attorney to represent you on your case, no. If you appear by yourself, then likely yes, you will be required to post bail in the amount of the fine before getting a trial date. The purpose of the bail is to assure your appearance at trial. If the court is going to send out a subpoena for the police and city attorney to appear with the evidence at a scheduled date, they don’t want you to flake out and waste everyone’s time. However, if an attorney appears on your behalf, the court will grant what is called an “O.R” (own recognizance) release, because the court will trust the attorney’s promise to appear.
