How Oregon DUI penalties are structured

Oregon's DUI penalties depend on two things: whether this is your first offense or you have prior convictions, and whether your blood alcohol content (BAC) was above a certain threshold. The state has mandatory minimum sentences for most DUI convictions, meaning a judge cannot sentence you below those minimums even if circumstances seem less serious. Penalties escalate sharply with each prior conviction within the past 10 years.

The penalties also differ based on whether you refused a breath or blood test. Refusal carries its own consequences separate from the DUI conviction itself. Oregon also distinguishes between a standard DUI (driving under the influence of alcohol or drugs) and a DUII (driving under the influence of intoxicants), though the penalties are the same.

Key Takeaways

  • A first-offense DUI in Oregon carries a mandatory minimum of 48 hours in jail, a fine of at least $1,000, and a one-year license suspension.
  • A second DUI within 10 years requires a minimum of 30 days in jail, a fine of at least $1,500, and a three-year license suspension.
  • A third DUI within 10 years is a felony charge with a minimum of 30 days in jail, a fine of at least $2,000, and a five-year license suspension.
  • Refusing a breath or blood test results in an automatic one-year license suspension on a first refusal, separate from any DUI conviction penalty.
  • Oregon's lookback period is 10 years, meaning only prior convictions within the past decade count toward determining your offense level.

First-offense DUI penalties in Oregon

A first DUI conviction in Oregon carries a mandatory minimum jail sentence of 48 hours. You cannot be released from this requirement, though the court may allow you to serve part of it through work-release or electronic monitoring programs. The fine is at least $1,000, and you will lose your driving privileges for one year.

In addition to jail and fines, you must complete a substance abuse treatment program. The court will order an alcohol and drug evaluation, and you will be required to complete whatever level of treatment the evaluator recommends. You will also face a $100 victim information fee and other court costs. Your license suspension begins when ready upon conviction, even if you appeal.

Second DUI within 10 years

A second DUI conviction within 10 years of a prior DUI is treated more severely. The mandatory minimum jail sentence is 30 days, and the minimum fine is $1,500. Your license suspension extends to three years. Like a first offense, you must complete a substance abuse treatment program based on an evaluation.

A second offense also triggers an ignition interlock device requirement. You must install and maintain an ignition interlock on any vehicle you drive for a period set by the court, typically at least one year. This device requires you to blow into a breathalyzer before the car will start. You pay for the installation and monthly monitoring yourself, which typically costs $60 to $100 per month.

Third or subsequent DUI within 10 years

A third DUI conviction within 10 years becomes a felony charge in Oregon, not a misdemeanor. The mandatory minimum jail sentence is 30 days, though felony sentences often run longer. The minimum fine is $2,000. Your license suspension lasts five years, and you must install an ignition interlock device.

A felony DUI conviction carries long-term consequences beyond the when ready sentence. You will have a permanent criminal record, which affects employment, housing, and professional licensing. You may also face additional penalties if the DUI involved an accident, injury, or property damage. A fourth or subsequent DUI within 10 years carries even harsher penalties, including longer mandatory jail time and extended license suspension.

Breath or blood test refusal consequences

If you refuse to take a breath or blood test when a police officer requests one, Oregon's implied consent law imposes an automatic license suspension. A first refusal results in a one-year suspension. A second refusal within 10 years results in a three-year suspension. A third refusal within 10 years results in a five-year suspension.

This suspension happens through the Department of Motor Vehicles, not the court, and it is separate from any DUI conviction penalty. You can request a hearing with the DMV to contest the suspension, but you must do so within 10 days of the arrest. Even if you win the hearing and the refusal suspension is lifted, you can still be convicted of DUI based on other evidence like field sobriety tests or officer observations.

Enhanced penalties for high BAC or aggravating factors

Oregon does not have a separate "aggravated DUI" category, but certain circumstances can result in enhanced sentences within the standard DUI framework. If your BAC was 0.15 or higher, the court may impose penalties above the mandatory minimum. If the DUI involved an accident with property damage or injury, the court typically sentences more severely.

Driving with a suspended license due to a prior DUI also increases penalties. If you are convicted of DUI while your license is already suspended for a prior DUI, you face additional criminal charges on top of the DUI itself. Transporting a minor (under age 18) while driving under the influence can also result in enhanced penalties and additional charges.

License suspension and reinstatement

Your license suspension begins when ready upon DUI conviction. You cannot drive during the suspension period, even with a restricted or work permit, unless the court grants a hardship exception. To request a hardship exception, you must show the court that you have no reasonable alternative transportation and that driving is essential for employment or medical treatment.

After your suspension period ends, you must reinstate your license through the Oregon DMV. You will need to pay a reinstatement fee (typically $100 to $200), provide proof of financial responsibility (SR-22 insurance), and pass a written test. If you had an ignition interlock device installed, you must provide proof that it was removed by an authorized installer before the DMV will reinstate your license.

Frequently Asked Questions

What counts as a prior DUI for Oregon's 10-year lookback period?

Only DUI convictions within the past 10 years count toward determining your offense level. A conviction from 11 years ago does not count, so you would be treated as a first offender. However, the court can still consider older convictions as part of your criminal history when deciding on sentencing within the mandatory minimum range.

Can I get my license back before the suspension period ends?

You can request a hardship exception from the court if you can prove you have no reasonable alternative transportation and driving is essential for work or medical care. The court has discretion to grant limited driving privileges, such as driving only to and from work. You must file a petition with the court that convicted you.

Do I have to install an ignition interlock device on a first DUI?

No, ignition interlock is required only on a second or subsequent DUI conviction within 10 years. On a first offense, the court may order it, but it is not mandatory. On a second or later offense, it is mandatory and you cannot remove it until the court-ordered period ends.

What happens if I refuse the breath test but am not convicted of DUI?

The refusal suspension from the DMV stands independently of the DUI conviction. Even if you are found not guilty of DUI in court, your license can still be suspended for the refusal itself. You would need to win a separate DMV hearing to overturn the refusal suspension.

Are DUI penalties different if drugs were involved instead of alcohol?

No, Oregon treats DUI (alcohol) and DUII (drugs or intoxicants) the same way for sentencing purposes. The mandatory minimums, fines, license suspensions, and other penalties are identical whether the impairment was caused by alcohol, marijuana, prescription medication, or other drugs.
