Study Notes
Standardized Field Sobriety Tests (SFSTs)
- SFSTs are three accurate and reliable tests to determine alcohol or drug impairment during a DUI investigation
- The three tests are HGN (Horizontal Gaze Nystagmus), Walk-and-Turn, and One-Leg Stand
Effects of Alcohol on the Human Body
- Alcohol is a central nervous system depressant that can impair fine motor skills, hand-eye coordination, and judgment
- The human body processes alcohol through absorption, distribution, metabolism, and elimination
- Any amount of alcohol can affect a person's ability to drive
- Factors that influence the degree of impairment include the amount and duration of alcohol consumption, individual physiology, and food consumption
Driver Impairment Cues
- Common mental and physical effects of alcohol include:
- Slowed reactions and perception-reaction time
- Poor judgment
- Taking risks
- Poor coordination
- DUI motorcyclist visual cues include:
- Drifting during turns or curves
- Trouble dismounting
- Trouble balancing at a stop
- Problems turning (unsteadiness, sudden corrections, late braking, improper lean angle)
- Weaving
- Moving erratically while going straight
- Operating without lights at night
- Driving recklessly (e.g., driving on one wheel or at high speeds)
- Following too closely
- Running a stop light or sign
- Evading the officer
- Going the wrong way
- Vehicle stop cues include:
- Attempting to flee
- Not responding
- Responding slowly
- Swerving abruptly
- Stopping suddenly
- Striking the curb or another object
HGN Testing
- The HGN test is administered to check for nystagmus, which is a pathological disorder or a result of high doses of a drug like PCP
- Instructions for the HGN test include:
- Stand with feet together and hands down at sides
- Keep head still and follow a small object with eyes only
- Do not move head
- The object should be positioned about 12-15 inches from the driver's nose and slightly above eye level
- Check for resting nystagmus and equal pupil size
- Check for equal tracking by moving the object smoothly across the driver's entire field of vision two times
Walk-and-Turn Test
- Instructions for the walking stage of the walk-and-turn test include:
- Walk heel-to-toe along a straight line
- Keep arms at sides
- Count steps out loud
- Watch feet at all times
- Clues to look for during the walking stage include:
- Stopping
- Missing heel-to-toe
- Stepping off the line
- Using arms for balance
- Improper turn
- Incorrect number of steps
DUI Report
- A clear and comprehensive DUI report should establish the following elements:
- 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 provided additional evidence relevant to the alleged offense
- The officer made a lawful request for the accused to submit to a breath, urine, or blood test, and the results of the test
