Sample alcohol & drugs questions

  1. For a driver 21 or older, at what blood alcohol concentration (BAC) is driving always illegal in Tennessee?

    • A 0.10 percent or higher
    • B 0.02 percent or higher
    • C 0.05 percent or higher
    • D 0.08 percent or higher
    Show answer

    D. 0.08 percent or higher

    A BAC of 0.08 percent or more is always illegal for adult drivers in Tennessee. You can still be convicted of DUI below 0.08 if you are impaired, so the only safe amount before driving is none.

  2. A 17-year-old driver is found with a BAC of 0.02 percent. What offense is this in Tennessee?

    • A Only an open-container violation
    • B Underage driving while impaired
    • C Only a warning, since it is a first offense
    • D No offense, because it is below 0.08
    Show answer

    B. Underage driving while impaired

    Drivers who are at least 16 but under 21 are convicted of underage driving while impaired at a BAC of just 0.02 percent. Young drivers are affected by small amounts of alcohol because of low tolerance and little experience.

  3. You are arrested for DUI and refuse an officer's request to take a blood or breath test. What is the likely result?

    • A Nothing, because the test is voluntary
    • B You are automatically found not guilty of DUI
    • C A 30-day suspension
    • D Your license is suspended by the court for 12 months
    Show answer

    D. Your license is suspended by the court for 12 months

    Under Tennessee's Implied Consent Law, refusing a requested test after arrest will likely lead to a 12-month suspension. Under the No Refusal law, officers can also seek a search warrant for a blood sample.

    • B Police must get your written consent before searching your car
    • C By driving, you have agreed to be tested for alcohol or drugs
    • D Passengers agree to wear seat belts
    Show answer

    C. By driving, you have agreed to be tested for alcohol or drugs

    By driving in Tennessee, you have already given consent to be tested for alcohol or drugs when an officer has reasonable grounds to believe you are impaired. Refusing brings its own penalties.
