You took a prescribed medication in Oregon and feel groggy. Which statement about Oregon's DUII law is correct?
-
A.
DUII charges apply only to alcohol and illegal drugs.
-
B.
DUII applies only if the medication is a controlled substance.
-
C.
DUII requires a BAC of 0.08% or higher.
-
D.
DUII applies to any impairing substance, including medications. Correct
The answer is "DUII applies to any impairing substance, including medications."
Oregon's DUII law applies to any substance that impairs your mental or physical ability to drive, including over-the-counter and prescription medications. The trigger is impairment itself, not whether the substance is alcohol, a scheduled drug, or a legal prescription. Drivers picking A anchor on the familiar DUI headlines about alcohol and street drugs and assume a legal medication cannot land them in the same charge.
The traps in the wrong answers
A. DUII charges apply only to alcohol and illegal drugs.
Oregon's DUII law covers any impairing substance, including over-the-counter and prescription medications; the manual makes impairment, not the substance's category, the trigger. Takes its cue from the headline DUI stories about alcohol and street drugs and assumes a legal medication cannot land you in the same charge.
B. DUII applies only if the medication is a controlled substance.
The manual ties DUII to impairment, not to a drug's schedule. A driver impaired by a non-scheduled cold medicine or common antihistamine can still be arrested for DUII in Oregon. Treats a prescription label or over-the-counter status as a legal shield the DUII statute does not recognize.
C. DUII requires a BAC of 0.08% or higher.
The manual says a driver can be arrested for DUII even when BAC is below 0.08%, and DUII covers non-alcohol impairment where BAC is not measured at all. Confuses the 0.08% presumption of alcohol impairment with a required threshold for every DUII arrest.
