  1. 1. Which statement about drugs and driving in Florida is correct?

    Correct answer: Prescription and over-the-counter medicines can impair driving and lead to a DUI

    Driving under the influence covers any impairing substance—including legal prescription and over-the-counter medicines. Read labels for warnings and do not drive if a medication can affect your alertness or coordination.

  2. 2. You take a cold or allergy remedy and later have a single alcoholic drink. What is the likely result?

    Correct answer: The two together can impair you like several drinks would

    Putting the two together often multiplies what each one does. One drink taken alongside a common cold or allergy medicine can leave you as impaired as a far larger amount of alcohol would on its own.

  3. 3. A driver 21 or older is considered legally impaired (DUI) in Florida at a blood-alcohol level of:

    Correct answer: 0.08

    For drivers 21 and over, a blood- or breath-alcohol level of 0.08 or higher is legal impairment. You can still be charged below that level if your driving is impaired.

  4. 4. A driver under 21 is stopped and registers a blood-alcohol level of .05. Besides losing the driving privilege, that driver is also required to:

    Correct answer: Finish a substance abuse course

    Zero tolerance suspends any driver under 21 from .02 upward. Once the reading reaches .05 the driver must also sit a substance abuse course, and an evaluation is carried out afterwards.

  5. 5. Under Florida's 'implied consent' law, what happens if you refuse a lawful test of your breath, blood, or urine?

    Correct answer: Your driving privilege will be suspended

    By driving in Florida you agree (implied consent) to chemical testing if you are lawfully arrested for DUI. Refusing results in an automatic suspension of your driving privilege.

  6. 6. As a person drinks alcohol, which driving-related ability is usually affected first?

    Correct answer: Judgment and self-control

    Alcohol affects judgment, reasoning, and self-control first—often before a person feels drunk. That is why drivers who have been drinking take risks and misjudge speed and distance.

  7. 7. Can you be charged with DUI while sitting in a parked car whose engine is switched off?

    Correct answer: Yes — having physical control of the vehicle while impaired is enough

    The offense covers driving or having actual physical control of a vehicle while impaired by alcohol, illegal drugs, or even prescribed and over-the-counter medicine, so the car need not be moving at all.

  8. 8. How long does a DUI conviction stay on a Florida driving record?

    Correct answer: Seventy-five years

    Florida keeps a DUI conviction on the record for 75 years, so one conviction can follow a driver for the rest of their life.

  9. 9. What happens to the driving privilege of a person convicted of possessing or selling illegal drugs, even when no vehicle was involved?

    Correct answer: The license has to be suspended

    A drug conviction, marijuana included, forces a suspension of the license under Florida law. Where a car was used to carry or sell the drugs, that vehicle may also be seized.

  10. 10. Under Florida's zero-tolerance law, a driver under 21 can lose their license at a blood-alcohol level as low as:

    Correct answer: 0.02

    Drivers under 21 are held to a zero-tolerance standard: a blood-alcohol level of 0.02 or higher—about one drink—triggers a license suspension.
