8. RADAR/LIDAR Stationary mode Moving mode Impacted by – Weather conditions – Size of target (Radar) – Angle in beam (Cosine effect)

9. Impounds Tow away report – Vehicle inventory – Damage – Contents Department policy required Contraband can be seized Private tows – Recorded in dispatch – repossessions or private property

10. Operating Under the Influence National Highway Traffic Safety Administration (NHTSA) List of 24 cues developed Based on 3 field studies and 12,000 traffic stops

11. Operating Cues Problems in maintaining proper lane position Speed and braking problems Vigilance problems Judgment problems Predict impaired operation at least 35% of the time Combining cues increases accuracy

12. Problems Maintaining Proper Lane Position Weaving Weaving across lane lines Straddling a lane line Swerving Turning with a wide radius Drifting Almost striking a vehicle or other object Probability =.50 -.75

13. Speeding and Braking Problems Stopping problems – Too far – Too short – Jerky Accelerating or decelerating for no apparent reason Varying speed Slow speed (10+ mph under limit) Probability =.45 -.70

14. Vigilance Problems Driving in opposing lane or wrong way on one way Slow response to traffic signals Slow or failure to respond to officer’s signals Stopping in lane for no apparent reason Driving without lights at night Failure to signal or signal inconsistent w/action Probability =.55 -.65

19. Field Sobriety Tests Standardized Field Sobriety Tests – Horizontal Gaze Nystagmus (HGN) – Walk and Turn – One Leg Stand Based on research from the National Highway Traffic Safety Administration (NHTSA)

20. HGN About 88% accuracy Person instructed to follow an object in horizontal motion – with their eyes only Impaired – Difficulty smoothly tracking – Distinct jerking at maximum deviation – Jerking begins within 45 degrees of center

21. Walk and Turn Divided attention – listen & follow instructions while doing simple movements Nine steps heel-to-toe in straight line – then turn on one foot and return the same way in the opposite direction 79% who give 2 or more indicators will have BAC of.08 or more

22. Walk and Turn Can’t maintain balance while being instructed Begins before instructions are finished Stops while walking to regain balance Doesn’t touch heel-to-toe Steps off the straight line Uses arms to balance Makes the turn improperly Takes an incorrect number of steps

23. One Leg Stand Instructed to stand with one foot off the ground six inches for 30 seconds and count aloud (one thousand one…) Indicators – Swaying while balancing – Using arms to balance – Hopping to maintain balance – Putting the raised foot down 83% of those with 2 or more indicators will have a BAC of.08 or more

24. Combined Accurate in 91% of the cases when the clues from the 3 components are combined

25. BAC Tests Implied Consent.08 limit Strict liability law – no intent required to be proven Balloon test Intoxilyzer Blood

26. Accidents Public way or where public traffic can be reasonably anticipated Bodily injury or death $1000 in damage Report by quickest means possible Fatal accidents must be investigated by a full time officer

27. Accidents Commercial vehicle requires Commercial Vehicle Enforcement to respond Late reported accidents – Both parties – Estimates – View both vehicles Unattended vehicles – locate owner & exchange info

28. Accidents Accident scene can be a crime scene and needs to be treated as such Other hazards present – wires down, traffic, hazardous materials, biological material Don’t move cars if the accident has extensive damage or injury

29. Accidents May need to mark items that may be moved Reconstruction begins with the final rest position of what is involved – vehicles, people, items from car
