Assault in the Third Degree in Oregon is a Class C felony under ORS 163.165, punishable by up to five years in prison and a fine of up to $125,000. The statute lists ten distinct ways to commit the crime, ranging from recklessly causing serious injury with a weapon to knowingly hurting a child aged 10 or younger. Because it is a felony rather than a misdemeanor, a conviction reaches well past any sentence: federal firearm rights, immigration status, and professional licenses are all in play.
What ORS 163.165 Actually Covers
The statute is broader than most people expect. It groups into three general categories.
The first covers reckless conduct that causes harm. A person commits Assault 3 by recklessly causing serious physical injury with a deadly or dangerous weapon, by recklessly causing serious physical injury under circumstances showing extreme indifference to human life (no weapon required), or by recklessly causing physical injury with a deadly or dangerous weapon under circumstances showing extreme indifference to human life. That last path is the one that reaches ordinary (non-serious) injuries, but only when both a weapon and extreme indifference are present.
The line between “physical injury” and “serious physical injury” matters. Physical injury means impairment of physical condition or substantial pain. Serious physical injury requires a substantial risk of death, serious and lasting disfigurement, or prolonged impairment of health or loss of a body part’s function.
The second category protects specific victims. Causing physical injury to any of the following is enough for a felony charge, without a weapon and without recklessness or extreme indifference:
- A public transit operator (bus driver, light rail operator, or similar) while operating or controlling the vehicle, when the injury is caused by means other than a motor vehicle.
- A taxi driver while controlling the vehicle, again limited to non-vehicular means.
- An emergency medical services provider performing their duties.
- A flagger or highway worker while working.
- A staff member at a youth correction facility, if the person committing the assault is committed to that facility.
- A child aged 10 or younger, if the person committing the assault is 18 or older and acts intentionally or knowingly.
The child-victim subsection is the most unforgiving. There is no weapon requirement, no recklessness threshold, and, as covered below, no path to set the conviction aside later.
The third category is the aided-by-another provision. Under ORS 163.165(1)(e), if two or more people act together and one of them intentionally or knowingly causes physical injury while another is actually present at the scene, the person inflicting the harm faces a felony rather than a misdemeanor. No gang affiliation is required. A bar fight where one person holds the victim while the other strikes is enough. The accomplice has to be present, though, not just involved from a distance.
Deadly Weapons Versus Dangerous Weapons
Several subsections turn on whether a weapon was involved, and Oregon separates the two categories. A deadly weapon is an object designed to cause death or serious injury, such as a firearm or a combat knife. A dangerous weapon is broader: any object that, given how it is used, could readily cause death or serious injury. A baseball bat, a glass bottle, or a car can qualify depending on how it was wielded. The test is what the object could have done under the circumstances, not what injury actually resulted.
When the Charge Becomes a Class B Felony
Assault 3 jumps from a Class C to a Class B felony when two conditions are both met: the assault resulted from operating a motor vehicle, and the driver was under the influence of intoxicants. This enhancement applies only to the serious-injury subsections, ORS 163.165(1)(a) and (1)(b).
The maximum prison term doubles from five years to ten. In a case where a drunk driver causes a crash resulting in serious physical injury and the driver acted recklessly, prosecutors can charge Assault 3 as a Class B felony instead of relying on a standalone DUII charge.
How Assault 3 Compares to Assault 2 and Assault 4
Oregon’s assault statutes form a ladder, and the rung matters.
Assault in the Fourth Degree (ORS 163.160) is the baseline. It is normally a Class A misdemeanor and covers intentionally, knowingly, or recklessly causing physical injury, or negligently causing injury with a deadly weapon. Certain aggravators (committing the assault in front of a minor child, assaulting a pregnant person, or a pattern of prior convictions against the same victim) can push it up to a Class C felony.
Assault in the Second Degree (ORS 163.175) sits above Assault 3. It is a Class B felony and requires a more culpable mental state: intentionally or knowingly causing serious physical injury, or intentionally causing physical injury with a deadly or dangerous weapon. Assault 3 generally requires only recklessness. When prosecutors can prove the defendant meant to cause the harm rather than consciously disregarded a risk, the charge moves up to Assault 2. Assault 2 is also a Measure 11 offense with a mandatory minimum of five years and ten months. Assault 3 is not subject to Measure 11.
What Sentencing Actually Looks Like
The five-year and ten-year ceilings are the statutory maximums. Few defendants receive them. Oregon uses a sentencing guidelines grid maintained by the Criminal Justice Commission that plots the offense’s seriousness ranking against the defendant’s criminal history score. The intersection gives a presumptive sentence: either a range of prison months or probation with jail sanctions. Judges can depart from the grid, but they need to state their reasons on the record.
For a first-time offender on a lower-seriousness felony, the grid often lands in probation territory. Probation typically comes with community service, restitution to the victim, anger management coursework, and regular reporting to a probation officer. A probation violation can trigger revocation and a prison term within the grid range.
Defenses That Can Work
The most common defense to an Assault 3 charge is self-defense. Under ORS 161.209, a person may use physical force when they reasonably believe it is necessary to defend themselves or a third person from the imminent use of unlawful force, and the force used must be reasonable in degree. Oregon does not require retreat before using non-deadly force, so a defendant does not have to prove they tried to walk away.
Self-defense claims usually fail on proportionality. Responding to a shove with a tire iron is unlikely to strike a jury as reasonable. The defense also does not protect someone who started the confrontation.
Oregon’s choice-of-evils defense under ORS 161.200 is available in narrow circumstances where the defendant’s conduct was necessary as an emergency measure to avoid a clearly greater imminent harm. It comes up rarely in assault cases.
Another line of defense is challenging the required mental state. Recklessness means the defendant was aware of a substantial and unjustifiable risk and consciously disregarded it. That is a higher bar than negligence. If the defendant genuinely did not perceive the risk, the conduct might support a lesser charge but not Assault 3. Subsections protecting specific victim categories also require proof the defendant knew the victim’s status, such as knowing someone was a staff member at a youth facility.
Consequences Beyond Prison
For many defendants, the collateral effects outlast the sentence.
Firearms
Federal law permanently prohibits anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition. Assault 3 carries a five-year maximum (ten with the DUI enhancement), so every conviction triggers the federal ban, even if the sentence is probation with no jail time. Violating the ban is a separate federal felony.
Immigration
For non-citizens, the stakes are severe. Federal immigration law treats a crime of violence with a prison term of at least one year as an aggravated felony, which triggers mandatory detention, bars nearly all relief from removal (including asylum), and results in permanent inadmissibility. Even sentences under one year can qualify as crimes involving moral turpitude, which independently opens the door to deportation proceedings.
Professional Licenses
Licensing boards in healthcare, education, law enforcement, and other regulated fields routinely ask about felony convictions. An Assault 3 conviction can lead to denial, suspension, or revocation of a license, especially where the conviction involves violence against a vulnerable victim. Some boards impose conditions like probationary licensing or required rehabilitation programs instead of outright revocation.
Setting a Conviction Aside Later
Oregon allows some felony convictions to be set aside under ORS 137.225, which functions like expungement in other states. For a Class C felony, the waiting period is five years from the date of conviction or release from imprisonment, whichever is later. For the Class B version created by the DUI enhancement, the waiting period is seven years.
The person must have completed the full sentence, including probation or post-prison supervision. They cannot have other criminal convictions (traffic violations aside) during the waiting period, and no charges can be pending when they file.
One category of Assault 3 is permanently ineligible: convictions under ORS 163.165(1)(h), the subsection covering adults who injure children aged 10 or younger. That exclusion is written into the statute, and no amount of time or rehabilitation removes it. Every other subsection remains eligible once the waiting period and conditions are met, though the court keeps discretion to deny the motion.
