Is there another option besides in court for a trial?

You can have a "trial by affidavit," where you submit written sworn testimony under oath to the judge. ORS 153.080. The testimony must be in the form of an affidavit, and your signature must be notarized. The judge reads your affidavit at trial and makes a decision. A witness can also submit a written affidavit. To request a trial by affidavit, enter a not guilty plea and ask for a trial by affidavit. In this process, you give up your right to ask the officer questions.
