DUII and DUI in Portland, OR: the Multnomah County court, the deadlines and choosing a lawyer
A drunk driving arrest in Portland — Oregon charges it as DUII, driving under the influence of intoxicants — runs on two clocks at once. The criminal case goes to the Multnomah County court, and your license is handled separately by the state. That second deadline is the short one, and it does not wait for your court date.
In Oregon it is called DUII, not DUI
DUII stands for driving under the influence of intoxicants. Court paperwork, the police report and Oregon attorneys all use that term, so searching for a «DUI lawyer» in Portland turns up firms describing the same work under a different label.
Multnomah County handles DUI cases from Portland
Portland lies in Multnomah County and its city limits also reach into Washington County and Clackamas County — if you were stopped on that side of town, the case may be filed there instead. The city has about 630,498 residents, and local practice matters more than most people expect: prosecutors in one county run diversion programs that the next county does not offer, and the judges who hear these cases week after week have known preferences on sentencing.
This is the practical argument for hiring locally rather than by search ranking. An attorney who appears in Multnomah County regularly knows which prosecutor is handling the docket and what a realistic outcome looks like there — knowledge that does not transfer from a neighboring county.
How common drunk driving cases are in Multnomah County
Federal crash records show what the county deals with. It is worth knowing before your first hearing, because it shapes how routinely local prosecutors handle these cases — and how little novelty your argument will have.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. Counts fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Multnomah County sits at or below the Oregon average. Counties inside one state are broadly comparable, because testing practice is set at state level; comparing across state lines is not, and we do not do it here.
What a conviction triggers, whatever the county
These follow the conviction itself and are not negotiable with a prosecutor. Knowing them is how you judge whether fighting the charge is worth the cost.
- Interlock term: Set by ORS 813.602 for the underlying suspension; the hardship permit runs alongside it and requires the device on any vehicle you drive
- Lockout threshold: Set by the device standard the DMV approves; the requirement itself is imposed by law rather than by the permit
- Program run by: Oregon DMV (Department of Transportation), with the court on diversion cases
- Device cost in Oregon: not published by Oregon — nationally about $70 a month

What a Portland DUII attorney actually handles
«DUII lawyer» covers several different fights. Which one you are in decides what the first consultation should be about.
What each of these means under Oregon law →
Injured by a drunk driver, not charged?
That is a different area of law. A defense attorney represents the person facing the charge; a claim for injuries or the loss of a family member is handled by a personal injury attorney, and the two rarely overlap in one firm. Search for a personal injury or wrongful death attorney in your county rather than a defense lawyer.

Asked about DUII cases in Portland
Where is a Portland DUII case heard?
Portland sits in Multnomah County, so a DUII arrest here is normally prosecuted in that county's court. Some Oregon municipalities run their own courts for lesser traffic offenses, and which court you land in affects both timing and local practice — an attorney who appears there regularly will know which.
How much does a DUII lawyer cost in Portland?
Fees are set by the individual firm, not by Oregon, and vary with whether the case is resolved by plea or goes to trial. Most attorneys give the first consultation free, so the useful first step is establishing what your case actually involves before discussing price.
Do I need a DUII attorney if I plan to plead guilty in Portland?
The license side of a drunk driving case moves separately from the criminal case and on a much shorter clock: Oregon sets the interlock requirement at length of suspension. Pleading guilty does not pause that deadline, which is why the first consultation is normally about the license, not the plea.
Where do I install an interlock after a Portland conviction?
There are 9 certified installers in Portland. Oregon requires the device to come from a provider the state has approved, so the choice is between approved providers, not between any auto shop.
