Sorting out dui & traffic violations in Oregon: refusal-warning record, response timing, and what deserves review first

Oregon calls it DUII — Driving Under the Influence of Intoxicants — a name that reflects both the statutory text of ORS 813.010 and the breadth of what constitutes the offense. Unlike states where the impaired driving law is written primarily around alcohol with drugs treated as a secondary category, Oregon's DUII statute is written in terms of "intoxicants" from the outset, encompassing alcohol, controlled substances, inhalants, and any combination thereof within a single criminal provision. A Portland driver who smoked cannabis from an OLCC-licensed dispensary two hours before driving and registers 0.04% BAC from a glass of wine with dinner is potentially impaired by multiple intoxicants simultaneously — and Oregon's DUII law reaches that combination without requiring the prosecution to choose between an alcohol theory and a drug theory. The challenge for law enforcement and prosecutors is that while Oregon has a per se BAC limit of 0.08% for alcohol, no per se drug impairment standard exists for cannabis, opioids, or other substances — proving cannabis DUII requires expert testimony from a Drug Recognition Expert (DRE) and evidence of actual impairment, not a threshold blood level.

Oregon's DUII diversion program — ORS 813.225 through 813.270 — is the most consequential first-offense tool in the Oregon DUII defense arsenal. A first-time DUII defendant in Oregon can petition to enter a one-year diversion program: pay $1,225 in diversion fees, submit to an alcohol and drug evaluation, complete any recommended treatment, install an ignition interlock device (IID) on all vehicles they drive for the duration of the diversion period, and attend a victim impact panel. Upon successful completion, the criminal case is dismissed — no conviction, no record. Oregon's diversion is a once-in-a-lifetime opportunity: it cannot be used if the defendant has been convicted of any DUII in the preceding 15 years, or if the defendant used diversion in the preceding 15 years. For a commercial driver — whose career depends on maintaining a clean record — the one-time diversion may be the single most valuable procedural benefit Oregon's DUII law offers.
