Trial by Affidavit in Oregon: How to Fight a Moving Violation Without Going to Court

What is a Trial by Affidavit in Oregon?

Getting a traffic ticket in cities like Portland, Salem, or Eugene can ruin your day, but fighting it does not mean you have to miss a day of work. Under Or. Rev. Stat. § 153.080, Oregon allows drivers to contest moving violations through a process known as a Trial by Affidavit. Instead of standing before a judge and questioning the police officer in person, you submit a sworn written statement outlining your version of events. The officer who cited you will also submit their written notes. A traffic judge will then review both documents in their chambers and mail you a verdict. This is an excellent option for drivers who live out of state or those whose work schedules prevent them from attending a physical hearing at the Multnomah County Circuit Court, Portland or the Washington County Circuit Court, Hillsboro.

How to Draft Your Written Statement

Writing a successful affidavit requires structure, clarity, and a focus on legal facts rather than emotions. A traffic judge is not interested in reading a long rant about how unfair the officer was or how much you cannot afford the ticket. You must focus on disproving the specific elements of the violation.

Step 1: Use the Correct Court Form

First, you must notify the court that you plead not guilty and wish to proceed by affidavit. You will typically need to complete and submit Form Declaration, Oregon, Circuit Court, Declaration - Trial by Declaration (or the specific local equivalent provided by your county court). This form includes a waiver of your right to a live trial and your right to cross-examine the officer.

Step 2: Stick to the Facts and Attach Evidence

Your written statement should be concise. If you were cited for running a red light, but the light was yellow when you entered the intersection, state exactly that, referencing your speed and distance. You are allowed to attach evidence to your affidavit. Including photographs of obscured speed limit signs, diagrams of the intersection, or a GPS log of your speed can significantly strengthen your case. Ensure that all statements are truthful, as you are signing the document under penalty of perjury.

Deadlines for Submission

Missing a deadline is the fastest way to lose a Trial by Affidavit. Your plea of not guilty and your request for a written trial must be received by the court clerk on or before the initial appearance date listed at the bottom of your citation. Once the court approves your request, they will mail you a notice with a firm deadline by which your actual written affidavit and any evidence must be submitted. If the Marion County Circuit Court, Salem does not receive your paperwork by that specific date, you will automatically be found guilty by default.

How Judges Weigh Your Affidavit Against the Officer's Notes

In Oregon traffic courts, the burden of proof rests on the state (the police officer) to prove you committed the violation by a preponderance of the evidence. When you choose a Trial by Affidavit, the officer is not required to write a new, elaborate essay. Instead, the judge will typically review the officer's original handwritten notes on the back of the ticket or their digital report. If the officer's notes are vague or fail to establish a critical element of the offense (such as failing to note which lane you were in, or how they calibrated their radar), a well-written affidavit from you can tip the scales in your favor. Legal precedents like State v. Porter, 312 Or. 112 (OR Supreme Court 1991) highlight how critical precise officer documentation is in traffic enforcement.

What to Do if You Lose (Appeals)

If the judge finds you guilty based on the written submissions, they will mail you a judgment outlining the fine you must pay. If you believe the judge made a legal error (not just that you disagree with their opinion of the facts), you have the right to appeal the decision to the Oregon Court of Appeals. However, appealing a traffic violation is incredibly difficult, time-consuming, and expensive. If you lose your Trial by Affidavit, it is often more practical to simply pay the fine and consult a local traffic attorney from our directory to handle any future citations before they compound on your driving record.

Costs Associated with Fighting a Ticket

Fighting a ticket by affidavit is generally cost-effective since you do not have to pay for parking, take a day off work, or necessarily hire a lawyer for a simple infraction.
