    Study Notes

    DUI Detection Process

    • The DUI detection process begins when a driver is suspected of being impaired and ends when there is or is not sufficient probable cause to arrest for a DUI offense.
    • The process involves three phases: vehicle in motion, personal contact, and pre-arrest screening.

    Phase One: Vehicle in Motion

    • Observing the way the driver operates and stops the vehicle
    • Visual cues that may indicate an impaired driver:
      • Lane position problems (weaving, drifting, straddling a lane line, etc.)
      • Speed and braking problems (stopping problems, accelerating or decelerating unnecessarily, etc.)
      • Vigilance problems (driving without headlights at night, failing to signal, etc.)
      • Judgment problems (following too closely, conducting an improper lane change, etc.)

    Phase Two: Personal Contact

    • Observing and speaking with the driver face to face
    • Look for clues, such as:
      • Unable to follow instructions
      • Unable to open the door
      • Leaves the vehicle in gear
      • Climbs out of the vehicle
      • Sways or staggers while walking
      • Leans against the vehicle or another object
      • Places hands on the vehicle for balance

    Phase Three: Pre-arrest Screening

    • Administering the Standardized Field Sobriety Tests (SFSTs) to determine probable cause to arrest for DUI
    • SFSTs consist of:
      • Horizontal Gaze Nystagmus (HGN) test
      • Walk and turn test
      • One-leg stand test

    Horizontal Gaze Nystagmus (HGN) Test

    • An involuntary jerking of the eyes as they move toward the side
    • Move the stimulus all the way across the driver's face to check the left eye, holding that position for a minimum of four seconds
    • Repeat the procedure for the right eye
    • Look for distinct and sustained nystagmus at maximum deviation
    • Check for the onset of nystagmus prior to 45°

    Walk and Turn Test

    • A divided attention test that measures a person's ability to perform both mental and physical tasks at the same time
    • Check for clues, such as:
      • Not counting out loud
      • Counting an incorrect number of steps
      • Turning in the wrong direction
      • Utering incriminating statements during the test
    • Document the reason the test was stopped, if necessary

    One-Leg Stand Test

    • Conduct the test on a stable, level, and non-slippery surface, if possible
    • Certain drivers may have difficulty performing this test due to back, leg, or inner ear problems
    • Give the driver an opportunity to remove their shoes if necessary
    • The test consists of two stages: instructions stage and balance and counting stage

    DUI Basics

    • Impaired driving is a major cause of traffic fatalities in the United States, with drivers showing impairment due to various reasons such as alcohol, drugs, medical conditions, and mental or physical disabilities.
    • Impaired drivers are more likely to take excessive risks, have slow reaction times, and are less likely to wear seatbelts.
    • Education and deterrence are essential in preventing impaired driving, with law enforcement playing a crucial role in enforcing DUI laws and educating the community.

    DUI Traffic Stops

    • During a DUI investigation, a clue is a piece of evidence that suggests impairment, such as signs of drug or alcohol impairment, and can be observed through conversation and observation of the driver.
    • Task one of phase two of the DUI detection process involves observing and talking with the driver in the vehicle, which begins as soon as both vehicles have come to a complete stop.
    • The initial face-to-face contact with the driver may give the first indications of impairment, and the driver and occupants should be treated with fairness, dignity, and respect.
    • Under Florida law, a person is driving under the influence (DUI) if they are driving or in actual physical control of a vehicle while impaired by alcohol or certain chemical or controlled substances.
    • Normal faculties include a person's ability to see, hear, walk, talk, judge distances, drive an automobile, make judgments, act in emergencies, and normally perform the mental and physical acts of daily life.

    Phase Two—Personal Contact

    • Task two of phase two involves observing the driver exiting the vehicle, and based on these observations, the officer must make a major decision to administer SFSTs, continue dialoguing with the driver, or finish the contact if no impairment is observed.

    HGN Testing

    • The HGN test is used to detect impairment and involves observing the driver's eyes to provide clues of alcohol or drug impairment.
    • The test involves giving the driver instructions to stand with their feet together and hands down at their side, keeping their head still, and following a small object with their eyes only.
    • The object is moved smoothly across the driver's entire field of vision two times to check for equal tracking.

    DUI Arrest Report

    • A clear and comprehensive DUI arrest report should establish the following elements for the arrest:
      • Reasonable suspicion for stopping or contacting the accused
      • The accused was the driver or in actual physical control of the vehicle
      • Probable cause to believe the accused was impaired
      • The officer followed lawful procedure regarding the rights of the accused
      • The officer followed lawful arrest procedures
      • Subsequent observation and interview of the accused provided additional evidence relevant to the alleged offense
      • The officer made a lawful request for the accused to submit to the breath, urine, or blood test, and the results of the test
    • The report should be organized around the complete sequence of events from start to end, beginning with the first observation of the driver and ending with the incarceration or release of the person.
