Washington law

4 questions on Washington’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. In Washington, a person under 21 may not drive with an alcohol concentration of at least:

    • A0.08
    • B0.05
    • 0.02
    • D0.01

    Answer: 0.02. RCW 46.61.503 prohibits a person under twenty-one from operating with, within two hours after operating, an alcohol concentration of at least 0.02 but less than the adult threshold in RCW 46.61.502 (and also covers any THC concentration above 0.00 below the adult THC threshold).

  2. 2. Washington's adult per-se DUI alcohol concentration threshold is:

    • 0.08 or higher
    • B0.10 or higher
    • C0.02 or higher
    • D0.05 or higher

    Answer: 0.08 or higher. RCW 46.61.502 treats driving with an alcohol concentration of 0.08 or higher (within two hours after driving, as shown by analysis under RCW 46.61.506) as driving under the influence.

  3. 3. Unless an exception applies, a Washington intermediate license holder may not drive between:

    • A11 p.m. and 5 a.m.
    • BMidnight and 5 a.m.
    • 1 a.m. and 5 a.m.
    • D10 p.m. and 5 a.m.

    Answer: 1 a.m. and 5 a.m.. RCW 46.20.075(3) prohibits an intermediate licensee from operating between 1 a.m. and 5 a.m. except when accompanied by a licensed driver at least 25, or for school, religious, or employment activities for the holder or an immediate family member.

  4. 4. Before a Washington intermediate license, a parent/guardian certification must show at least:

    • A60 hours of driving, including 10 at night
    • B30 hours of driving, including 5 at night
    • C40 hours of driving, including 6 at night
    • 50 hours of driving, including 10 at night

    Answer: 50 hours of driving, including 10 at night. RCW 46.20.075 requires certification that the applicant has had at least 50 hours of driving experience, 10 of which were at night, supervised by a qualifying licensed adult.

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 Washington items above for 14 questions in total.

  1. 1. What is the only reliable remedy for driver fatigue?

    • AOpening the windows
    • BTurning up the radio
    • CCoffee or an energy drink
    • Sleep

    Answer: Sleep. Caffeine, cold air, and music mask drowsiness briefly. Only real sleep restores alertness, so stop somewhere safe and rest.

  2. 2. Prescription and over-the-counter medicines can affect driving by:

    • Causing drowsiness, blurred vision, or slowed reactions
    • BHaving no effect if legally prescribed
    • COnly affecting drivers over 65
    • DImproving concentration

    Answer: Causing drowsiness, blurred vision, or slowed reactions. Legality does not mean safety. Check labels and pharmacist advice for warnings about operating machinery.

  3. 3. What actually reduces the alcohol level in a person's body?

    • AA cold shower
    • Time
    • CStrong coffee
    • DExercise

    Answer: Time. The body removes alcohol at a steady rate. Nothing speeds it up, so only waiting long enough restores sober judgment.
