Blue lights in the rearview mirror can make even simple questions feel impossible. Can you refuse field sobriety tests in Oregon? Generally, yes. You can decline roadside coordination exercises such as walking heel-to-toe, standing on one leg, or following an officer’s finger with your eyes. But that choice has consequences, and it is not the same as refusing a breath, blood, or urine test after a DUII arrest.
The key is understanding what you are refusing, what the officer told you, and what happens next. A roadside stop may last minutes. The effects on your license, employment, and criminal case can last much longer.
Can You Refuse Field Sobriety Tests? Yes, But Know the Risk
Field sobriety tests are physical and attention-based exercises officers use to look for signs of impairment. The most common tests are the horizontal gaze nystagmus test, the walk-and-turn, and the one-leg stand. Officers may also ask you to perform other coordination tasks.
In Oregon, refusing field sobriety tests does not automatically create the same driver license suspension that can follow a chemical-test refusal. You are not required to perform roadside balancing exercises simply because an officer asks.
Still, a refusal is not invisible. Oregon law allows a refusal or failure to submit to field sobriety tests to be used as evidence in a civil or criminal case when the required advisement is given. An officer may report that you refused, and the prosecutor may argue that your refusal showed consciousness of guilt. Whether that evidence is legally admissible, and how much weight it carries, depends on the facts and the procedure used.
That is the trade-off. Completing the tests can provide the state with observations it will use against you. Refusing can give the state another fact to argue about. There is no universal answer that fits every stop.
Field Sobriety Tests Are Not Designed to Be Easy
These exercises can look simple from the outside. Under roadside conditions, they are often difficult for sober people.
You may be standing on uneven pavement, gravel, a sloped shoulder, or in poor lighting. Traffic may be passing nearby. You may be cold, exhausted, injured, anxious, wearing work boots, or dealing with a medical condition that affects balance. Age, weight, inner-ear issues, back pain, knee injuries, and certain medications can also matter.
The tests are also graded according to specific officer instructions. Missing a phrase, starting too early, raising your arms, stepping off an imagined line, or swaying slightly can be recorded as a clue of impairment. A defense case may focus on whether the officer gave proper instructions, chose a suitable location, fairly scored the exercises, or ignored obvious physical limitations.
The officer’s body camera footage can be critical. A written police report may say a driver “performed poorly.” Video can reveal a different picture: an unclear demonstration, bad weather, poor footing, or a driver who was cooperative but understandably nervous.
Do Not Confuse Roadside Tests With Oregon Implied Consent
This distinction matters. Field sobriety tests are one issue. Chemical testing after arrest is another.
Once an officer arrests you for DUII and requests a breath, blood, or urine test under Oregon’s implied consent law, refusing can trigger serious administrative consequences. A chemical-test refusal can lead to a license suspension and may become important evidence in the criminal DUII case. The exact consequences depend on the type of test requested, your driving history, and whether the officer followed the required legal procedures.
Do not assume that because you declined roadside exercises, you should automatically refuse a later chemical test. These are high-stakes decisions with different rules.
A police officer should provide implied consent warnings before requesting a qualifying chemical test. Those warnings, the timing of the arrest, the basis for the request, and the handling of any test can all become defense issues. The facts need to be reviewed quickly, not guessed at from a stressful night.
What to Do During a DUII Stop
You do not need to argue your case on the roadside. Arguing usually gives an officer more statements and observations to include in the report.
Be polite. Provide your license, registration, and insurance when requested. Do not lie or make admissions about drinking, marijuana use, prescription medication, or how much you consumed. You may clearly state that you do not wish to answer questions and that you want to speak with an attorney.
If an officer asks you to perform field sobriety tests, you can decline. Keep your response calm and direct. Do not turn the encounter into a confrontation, physically resist, or drive away. Refusing a roadside exercise does not stop the officer from arresting you if the officer believes there is probable cause.
If you are arrested, pay close attention to paperwork concerning your license. That paperwork may contain a temporary driving permit and notice of a proposed suspension. Keep it. The deadline to challenge an Oregon DUII-related license suspension is often just 10 days from the date notice is served.
Why the 10-Day DMV Deadline Cannot Wait
A DUII arrest can create two separate fights: the criminal case in court and the administrative license suspension process through the DMV. They overlap, but they are not the same proceeding.
Requesting a DMV hearing on time can preserve an opportunity to challenge the suspension, question the officer’s evidence, and obtain information early. Missing the deadline can mean losing that hearing opportunity, even if there are valid defenses in the criminal case.
The DMV hearing may involve questions such as whether the officer had reasonable grounds to believe you were driving while impaired, whether you were lawfully arrested, whether proper implied consent warnings were given, and whether the requested chemical test was properly administered. A field sobriety test refusal may be part of that factual record, but it does not decide every issue.
People often wait because they are hoping the problem will settle down. It does not. The deadline keeps running while you are working, caring for family, or trying to understand the paperwork.
A Refusal Does Not End the Investigation
Declining roadside tests may limit one source of evidence, but officers can still rely on driving behavior, odor, speech, admissions, eye appearance, witness statements, video, and chemical-test evidence. They may also seek a warrant for a blood draw in appropriate circumstances.
At the same time, the state’s evidence is not automatically strong because an arrest happened. DUII cases turn on details: why the stop occurred, what the officer observed before making contact, how questions were asked, whether body camera footage matches the report, and whether testing rules were followed.
This is especially relevant in marijuana DUII cases, cases involving prescription medications, and situations where a person appeared tired, ill, or anxious rather than impaired. Unlike alcohol cases with a reported breath result, drug impairment allegations frequently depend heavily on subjective officer observations. Those observations deserve careful scrutiny.
Get Advice Before the Evidence Disappears
If you were arrested in Bend or elsewhere in Central Oregon, do not wait for your first court date to start planning. Save every document you received, write down what happened while you remember it, and avoid discussing the arrest on social media. Details that feel minor now may matter later.
A DUII defense lawyer can evaluate the field sobriety test request, any refusal advisement, the chemical-test process, the DMV suspension notice, and possible options such as diversion when appropriate. The goal is not to promise an outcome. It is to identify the pressure points in the state’s case and protect your options before a deadline closes them.
Stop panicking and start planning your defense. A prompt, focused review can give you clarity when the arrest report and license paperwork are trying to do the opposite.
