  1. What are the three standardized field sobriety tests (SFSTs) approved by the National Highway Traffic Safety Administration (NHTSA)?

    Answer: Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand

    NHTSA has validated three SFSTs: Horizontal Gaze Nystagmus (HGN), Walk-and-Turn, and One-Leg Stand.

  2. What does the Horizontal Gaze Nystagmus (HGN) test measure?

    Answer: Involuntary jerking of the eye that increases with alcohol intoxication

    HGN measures the involuntary jerking of the eye (nystagmus) that becomes more pronounced as BAC increases.

  3. In Florida, what is the consequence of refusing a chemical test (breath, blood, or urine) after a lawful DUI arrest?

    Answer: Automatic license suspension and the refusal can be used as evidence of guilt

    Refusing a chemical test after a lawful DUI arrest in Florida results in a license suspension and the refusal itself can be used as evidence of guilt in court.

  4. What is a 'per se' DUI law?

    Answer: A law making it automatically illegal to drive at or above a certain BAC, regardless of observed impairment

    Per se DUI laws make it a crime to drive at or above the legal BAC limit (0.08% in Florida) without any need to prove the driver appeared impaired.

  5. How does alcohol reach the brain after being consumed?

    Answer: It is absorbed into the bloodstream and carried to the brain via circulation

    Alcohol is absorbed into the bloodstream through the stomach and small intestine, then carried by the blood to the brain and other organs.

  6. What does a preliminary alcohol screening (PAS) device — used at the roadside — measure?

    Answer: An estimate of BAC to help the officer establish probable cause for arrest

    A roadside PAS or preliminary breath test gives an estimated BAC to help officers establish probable cause — it is not the evidentiary test used in court.
