Oregon law

3 questions on Oregon’s own driver fitness rules

These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.

  1. 1. Under Oregon’s zero-tolerance rule for drivers under 21, you will fail an alcohol test if you have a blood alcohol concentration of:

    • A0.05% or more only
    • B0.08% or more only
    • C0.02% or more only
    • Any amount

    Answer: Any amount. The Oregon Driver Manual states that if you are under 21, you will fail the test if you have a blood alcohol concentration of any amount — Oregon has a zero tolerance law.

  2. 2. For an Oregon driver 21 or older, you will fail a breath/blood alcohol test if your BAC is:

    • A0.10% or more
    • BAny detectable amount
    • C0.05% or more
    • 0.08% or more

    Answer: 0.08% or more. The Oregon Driver Manual states that if you are 21 or over, you will fail the test if your blood alcohol concentration is 0.08 percent or more, and that Oregon law also presumes impairment at 0.08% or more for DUII.

  3. 3. Before an Oregon driver license under age 18, you must generally have had an instruction permit for at least 6 months and:

    • 100 hours of supervised driving, or 50 hours plus an ODOT-approved traffic safety education course
    • BNo practice-hour requirement
    • C200 hours with a parent only
    • D25 hours of any driving

    Answer: 100 hours of supervised driving, or 50 hours plus an ODOT-approved traffic safety education course. The Oregon Driver Manual states that if you are under 18 and applying for a driver license, you must have had an instruction permit for at least 6 months and must have 100 hours of supervised driving experience or 50 hours plus an ODOT-approved traffic safety education course.

Driver fitness rules that hold in every state

A sample of the national driver fitness bank. All 10 are in the practice run, combined with the Oregon items above for 13 questions in total.

  1. 1. Driving while very angry or upset is dangerous because strong emotion:

    • AHas no measurable effect
    • BOnly matters in heavy traffic
    • CImproves reaction time
    • Narrows attention and encourages risk taking

    Answer: Narrows attention and encourages risk taking. Anger and distress consume mental capacity needed for hazard detection and make aggressive choices feel reasonable.

  2. 2. Which of these is an early warning sign of drowsy driving?

    • ANoticing signs sooner
    • BChecking mirrors more often
    • Drifting from your lane or missing an exit
    • DGripping the wheel more firmly

    Answer: Drifting from your lane or missing an exit. Lane drift, repeated yawning, heavy eyelids, and missed exits or signs all indicate that fatigue is already affecting your driving.

  3. 3. In all U.S. states, it is illegal for drivers 21 or older to operate a motor vehicle with a BAC of:

    • A0.10% or higher
    • B0.02% or higher
    • C0.05% or higher
    • 0.08% or higher

    Answer: 0.08% or higher. A Blood Alcohol Concentration (BAC) of 0.08% or higher is the national standard for driving under the influence for adult drivers.
