DUI and DWI refer to criminal offenses for operating a motor vehicle while impaired by alcohol, drugs, or a combination of both. In Portland, Oregon, the most commonly used statutory term is Driving Under the Influence of Intoxicants - often abbreviated as DUII - but many people use the terms DUI and DWI interchangeably. These laws are intended to protect public safety by penalizing impaired driving and by removing impaired drivers from the roads.
Prosecution can occur at two related but separate levels. First, there is the criminal prosecution brought by the local district attorney for the criminal offense of impaired driving. Second, there are administrative processes handled by state driver licensing authorities that can suspend or restrict your driving privileges after a failed chemical test or a refusal to take one. Both criminal and administrative consequences can take effect quickly after an arrest, so early action matters.
A lawyer can help at every stage from the initial arrest through possible trial, sentencing, and administrative license proceedings. Common situations where people typically need legal help include:
- Arrest after a traffic stop where the officer alleges impairment. The officer may rely on observations, field sobriety tests, and chemical tests. A lawyer can review whether the stop and arrest were lawful and whether the tests were properly administered.
- Chemical test refusal or a failed breath, blood, or urine test. Refusals and test results can trigger immediate administrative license actions and shape criminal charges. A lawyer can advise on deadlines and represent you at administrative hearings.
- High blood alcohol concentration or aggravating factors. Elevated BAC levels, an accident causing injury or property damage, or involvement in a crash with serious consequences often lead to enhanced charges or penalties. Skilled counsel can explore defenses and mitigation options.
- Prior DUI or DWI convictions. Repeat offenses increase penalties substantially and create more complex legal strategies for plea, sentencing, and license restoration. A lawyer can evaluate how prior records will affect your case and negotiate alternatives.
- Eligibility for diversion, restricted licenses, ignition interlock, or treatment-based programs. A lawyer can determine whether you qualify for alternatives to conviction and can help negotiate program participation with the prosecutor and the court.
Portland sits within Oregon and follows Oregon state law for DUII enforcement and penalties. Key aspects to understand include the following:
- Legal limits. For most adult drivers the per se blood alcohol concentration or BAC limit is generally recognized as 0.08 percent. Lower limits apply to commercial drivers and stricter rules apply to drivers under the legal drinking age. Being over the limit is a common basis for a DUII charge, but impairment can be charged even if BAC is below the legal limit when evidence shows the driver was unsafe to operate the vehicle.
- Implied consent and tests. Oregon has implied-consent principles. That means when you drive on public roads you generally consent to chemical testing if arrested for suspected impaired driving. Refusing a chemical test or failing a test can lead to administrative license suspension and may be used against you in court. Administrative actions often have short deadlines to request a hearing, so prompt action is essential.
- Administrative license actions. In addition to criminal charges, the state can pursue an administrative suspension or restriction of driving privileges through the Oregon driver licensing authority. These actions are separate from the criminal case and have their own procedures and deadlines. You may get a temporary permit in some circumstances or be required to install an ignition interlock device as a condition to drive.
- Penalties and enhancements. Penalties for a first-time DUII typically include fines, possible jail time, mandatory alcohol education or treatment, community service, and license consequences. Penalties increase with prior convictions, very high BAC readings, accidents causing injury or death, or when other criminal charges are filed along with the DUII. Repeat offenses may be classified as felonies depending on the facts and prior record.
- Local criminal justice framework. Arrests in Portland are typically handled by local law enforcement agencies and prosecuted by the Multnomah County District Attorney or the county where the offense occurred. Cases proceed in the local circuit courts. If you cannot afford a lawyer, you may be eligible for appointment of a public defender, but public defender resources vary and many defendants choose to hire private counsel for specialized DUII defense.
After an arrest, remain calm and cooperate with lawful instructions. Exercise your right to remain silent about the incident beyond identifying yourself. Ask for a lawyer as soon as possible. Note important facts while they are fresh - where you were, who was in the vehicle, names of witnesses, and what the officer said and did. Record any deadlines you receive about administrative hearings or license action and contact a lawyer quickly to preserve rights and challenge evidence.
You may face an immediate administrative action against your driving privileges if you fail or refuse a chemical test. Administrative suspensions or restrictions are separate from criminal court outcomes. There is often a short deadline to request an administrative hearing to contest a suspension, so it is important to get legal advice quickly to avoid an automatic loss of driving privileges.
Technically you can decline a chemical test, but refusal usually carries immediate administrative consequences and may be used against you in a criminal case. Refusal can trigger an automatic license suspension and may limit some defense options. A lawyer can explain the trade-offs and help you navigate test refusal consequences.
Penalties vary by case and prior record. A first conviction can include fines, possible jail time, mandatory alcohol or drug education programs, community service, probation, and license suspension or restriction. Repeat offenses and cases with injury or death lead to much harsher penalties, including longer jail or prison terms and felony charges in severe situations.
In many cases you may be eligible for a restricted license or required to install an ignition interlock device to drive legally after a DUII suspension. Eligibility depends on the circumstances of your arrest, prior convictions, and whether you request and win an administrative hearing or negotiate conditions in the criminal case. A lawyer can advise on your options and help pursue limited driving privileges when available.
Criminal convictions remain on your criminal record and can affect your driving record, employment, and housing options. State law determines how long a DUI conviction is visible to employers and the public, and prior convictions are often counted against you for enhancement purposes. Some limited relief options may exist years later, but a conviction can have long-term consequences, so early defense is important.
Jail is a possible outcome depending on the facts: level of impairment, prior record, whether an accident occurred, and applicable sentencing laws. First-time offenders sometimes receive probation, fines, and treatment requirements instead of jail, but judges can impose custodial sentences. Repeat offenders and those whose conduct caused injury or death face a much higher risk of jail or prison time.
Common defenses include challenging the legality of the traffic stop and arrest, arguing that field sobriety tests were improperly administered or unreliable, disputing the accuracy or handling of chemical tests, and presenting alternative explanations for driving behavior. A skilled lawyer will review police reports, video, test calibration and maintenance records, and witness statements to identify weaknesses in the prosecutor's case.
Costs vary widely depending on the lawyer's experience, whether the case goes to trial, and the complexity of the matter. Some attorneys offer free initial consultations and flat fees for certain services, while others charge hourly rates. If you cannot afford a private attorney you may be eligible for a public defender. Discuss fees and payment arrangements up front with any attorney you contact.
Plea bargains are common and can reduce charges or penalties, but they have long-term consequences. An experienced attorney can evaluate the strength of the prosecution's case, the realistic outcomes at trial, and whether a plea deal meaningfully reduces exposure. In many cases negotiating for reduced charges, alternative sentencing, or treatment options is a practical course of action - but each case is unique and should be considered carefully with legal counsel.

If you or someone you know faces a DUI or DWI arrest in Portland, consider the following practical steps:
- Do not delay contacting an attorney who has experience handling impaired driving cases. Time-sensitive administrative deadlines can affect your driving privileges and defense options.
- Preserve evidence. Write down everything you remember about the stop, arrest, and any field tests. Keep copies of police reports, court paperwork, citations, and any notices about license suspension or hearings.
- Attend all court and administrative hearings. Missing a hearing can result in default judgments, license suspensions, or bench warrants.
- Be cautious about statements you make to law enforcement or insurers. Limit your communications and consult your lawyer before providing detailed statements.
- Explore treatment and evaluation early if substance use might be an issue. Participating in a certified evaluation or treatment program may help demonstrate responsibility or be part of a negotiated resolution.
- If you cannot afford a private lawyer, ask about public defender eligibility and how to apply. If you hire a private lawyer, ask about fee structures, what services are included, and what to expect during the process.
Facing a DUI or DWI charge can be stressful and have serious consequences. Acting quickly, getting informed, and working with an experienced attorney gives you the best chance to protect your rights and reduce the long-term impact on your life.
