Sample alcohol & drugs questions

  1. In Idaho, a driver under 21 is considered to be driving under the influence at what blood-alcohol concentration?

    • A 0.04 or more
    • B 0.05 or more
    • C 0.08 or more
    • D 0.02 or more
    Show answer

    D. 0.02 or more

    Idaho sets a much lower limit for young drivers: 0.02 for anyone under 21, compared with 0.08 for drivers 21 and older. For an under-21 driver, even a single drink can be enough to reach it.

  2. Your BAC is 0.06 and you are 25 years old, but you have also taken a drug that impairs you. Can you be convicted of DUI in Idaho?

    • A No, because your BAC is below 0.08
    • B Yes, for being under the influence of other intoxicating substances
    • C No, unless you were driving a commercial vehicle
    • D Only if you refuse to take a breath test
    Show answer

    B. Yes, for being under the influence of other intoxicating substances

    A BAC under 0.08 is not a safe harbor. Idaho can convict you of DUI for being under the influence of other intoxicating substances, including drugs and medications, even when your alcohol level is below the limit.

    A. 90 days, with no driving at all for the first 30 days

    For a first test failure, ITD suspends your license for 90 days, and for the first 30 days you have absolutely no driving privileges. An ignition interlock is then required for one year after the suspension ends.
