Driver's License Test Prep
Oregon Practice DUI & Impaired Driving

An Oregon officer pulls you over and observes signs of impairment. Your breath test comes back at 0.06% BAC. Can you still be arrested for DUII?

  1. A.
    No, an officer cannot arrest you for DUII unless your BAC reaches 0.08% or higher.
  2. B.
    No, Oregon law sets the minimum DUII arrest threshold at 0.05% BAC.
  3. C.
    Yes, 0.08% creates a presumption of impairment but is not a floor for arrest. Correct
  4. D.
    Yes, but only after you refuse a follow-up blood or urine test.
The Why

The answer is "Yes, 0.08% creates a presumption of impairment but is not a floor for arrest."

Oregon's Impaired Driving section names 0.08% BAC as the level at which the law presumes impairment, but it explicitly states a driver can still be arrested with a BAC below that number when other evidence (driving behavior, field sobriety, officer observation) supports impairment. The 0.08% figure is a presumption, not an arrest floor.

Why the others miss

The traps in the wrong answers

A. No, an officer cannot arrest you for DUII unless your BAC reaches 0.08% or higher.

0.08% creates a presumption of impairment, not an arrest immunity below that level. Misreading: Treats the per-se BAC number as a hard floor for any DUII enforcement.

B. No, Oregon law sets the minimum DUII arrest threshold at 0.05% BAC.

Oregon has no statutory 0.05% threshold for DUII arrest. Misreading: Imports the 0.05% per-se limit used in Utah and many non-U.S. jurisdictions as if it applied in Oregon.

D. Yes, but only after you refuse a follow-up blood or urine test.

Refusing a chemical test triggers separate implied-consent consequences but is not a prerequisite for a DUII arrest. Misreading: Conflates implied-consent enforcement with the probable-cause grounds for the underlying arrest.
