Sample alcohol, drugs and oui questions

  1. 1. In Massachusetts, a driver age 21 or older is operating above the legal limit at what blood alcohol content (BAC)?

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

    A. 0.08 or higher

    You are over the legal limit if your BAC is 0.08 or higher. Drivers under 21 face penalties at a much lower level of 0.02.

  2. 2. You are 30 with no prior OUI offenses. You are arrested for OUI and refuse a breath test. How long will your license be suspended?

    • B. 30 days
    • C. 1 year
    • D. 180 days
    Show the answer

    D. 180 days

    Under the Implied Consent Law, a driver over 21 with no prior OUI offenses who refuses a chemical test loses their license for 180 days. Refusing brings a longer suspension than failing the test.

  3. 3. Your doctor prescribes a medicine that makes you drowsy. If you drive while impaired by it, what is true?

    • A. Only illegal drugs can lead to an OUI charge
    • B. It is legal as long as your BAC is 0.00
    • C. It is legal because the medicine was prescribed
    • D. You can be charged with OUI, just as with alcohol
    Show the answer

    D. You can be charged with OUI, just as with alcohol

    OUI laws apply to drugs as well as alcohol. You can be considered OUI with prescription drugs, because it is illegal to drive while impaired by any substance.

  4. 4. About how much can one standard drink raise an average person's blood alcohol content (BAC)?

    • A. 0.08
    • B. 0.02
    • C. 0.005
    • D. 0.10
    Show the answer

    B. 0.02

    One standard drink can raise an average person's BAC by about 0.02. Having more than one drink in an hour makes BAC rise further.
