4. To increase deterrence of DUI violations, and thereby reduce the number of accidents, deaths, and injuries caused by impaired drivers. ULTIMATE GOAL: ENFORCEMENT RELATED GOALS: 1. Understand enforcement’s role in general DWI/DUI deterrence. 2. Understand detection phases, clues, and techniques. 3. Understand requirements for organizing and presenting testimonial and documentary evidence in DWI/DUI cases.

5. Each year, tens of thousands of people die in traffic accidents. Throughout the nation, alcohol is the major contributor to traffic fatalities: Approximately half of the drivers who die in crashes have been drinking. Most drivers in fatal crashes were legally “Under the Influence”. Alcohol related crashes are about NINE TIMES more likely to result in death than are similar crashes that do not involve alcohol. It is conservatively estimated that the typical DUI violator commits that offense about 80 times a year. In other words, the average DWI/DUI violator drives while under the influence, once every four of five nights a week.

6. One approach to reducing the number of drinking drivers is general deterrence of DWI/DUI. General deterrence of DWI/DUI is based in the public’s fear of being arrested. Currently, however, for every DWI/DUI violator arrested, there are between 500 and 2,000 DWI/DUI violations committed. GENERAL DETERRENCE

7. 1. DUI violators vastly outnumber police officers. It is not possible to arrest every drinking driver each time they commit the offense of DUI. 2.Some officers are not highly skilled at DUI detection. They fail to recognize and arrest many DUI violators. 3. Some officers are not motivated to detect and arrest DUI violators. WHY IS THE DWI/DUI ARREST TO VIOLATIONS RATIO (1:2,000) SO LOW?

8. LEGAL OVERVIEW THE BASIC DUI LAW: A state’s basic DUI statute may be subtitled Driving While Under the Influence, or something similar. Typically the statute describes the who, what, where, and how of the offense in language such as: It is unlawful for any person to operate or be in actual physical control of any vehicle within this state while under the influence of alcohol and/or any drug.

9. ARREST In order to arrest someone for a basic DWI/DUI violation, a law enforcement officer must have probable cause to believe that all elements of the offense are present. That is, the officer must have probable cause to believe that: 1. The Person in question was Operating or in actual physical Control of a Vehicle (Truck, van, automobile, motorcycle, even bicycle, according to specific provisions in various states). 2. While Under the influence of alcohol, another drug or both.

10. IMPLIED CONSENT LAW The description of how much impairment in the ability to operate a vehicle will equate with driving while under the influence is not completely clear. To help resolve this difficulty, states have enacted Implied Consent Laws. The principle purpose of the implied consent law is to encourage people arrested for DWI/DUI to submit to a chemical test to provide scientific evidence of alcohol influence. The implied consent law usually includes language similar to the following: Any person who operates a motor vehicle upon the public highways of this state shall be deemed to have given consent to a chemical test for the purpose of determining the alcohol and/or drug content of blood when arrested for any acts alleged to have been committed while the person was operating or in actual physical control of a vehicle while under the influence of alcohol and/or any drug.

11. The implied consent law usually provides the driver with the statutory option to refuse the test. However, this option is not an unlimited right; the law also provides that the individual’s drivers license may be suspended or revoked if the refusal is found to be unreasonable. Including a provision for license suspension or revocation is a means of encouraging those arrested for DUI to submit to the test so that valuable chemical evidence may be obtained. IMPLIED CONSENT LAW CONTINUED

12. DWI/DUI DETECTION Detection is both the most difficult task in the DWI/DUI enforcement effort, and the most important DWI/DUI detection is defined as the entire process of identifying and gathering evidence to determine whether or not a suspect should be arrested for a DWI/DUI violation. The detection process begins when the police officer first suspects that a DWI/DUI violation may be occurring and ends when the officer decides that there is or there is not sufficient probable cause to arrest the suspect for DWI/DUI. Your attention may be called to a particular vehicle or individual for a variety of reasons. The precipitating event may be a loud noise, cloud of dust, an obvious moving violation, behavior that is unusual, but not necessarily illegal, an equipment defect, or almost anything else. The initial “Spark” of detection may carry with it an immediate, strong suspicion that the driver is under the influence; or only a slight, ill-formed suspicion; or even no suspicion at all at the time. In any case, it sets in motion a process wherein you focus on a particular individual and have the opportunity to observe that individual and to accumulate additional evidence.

15. The detection process ends when you decide to arrest or not to arrest the individual for DWI/DUI. That decision, ideally, is based on all of the evidence that has come to light since your attention first was drawn to the suspect. Effective DWI/DUI enforcers do not simply leap immediately to the arrest/no arrest decision. They proceed carefully through a series of intermediate steps, each of which helps to Identify the collective evidence.

16. DETECTION PHASES The typical DUI contact involves three separate and distinct phases: PHASE ONE; Vehicle in motion PHASE TWO; Personal Contact PHASE THREE; Pre-arrest screening In phase one, you usually observe the driver operating the vehicle. In phase two, after you have stopped the vehicle, there usually is an opportunity to observe and speak with the driver face to face. In phase three, you usually have an opportunity to administer some formal structured field sobriety tests to the driver to evaluate the degree of impairment.

17. PHASE ONE Your first task is to observe the vehicle in motion. Based on this observation, you must decide whether there is sufficient cause to command the driver to stop. Your second task is to observe the stopping sequence.

18. PHASE TWO Your first task is to observe and interview the driver face to face. Based on this observation, you must decide whether there is sufficient cause to instruct the driver to step from the vehicle for further investigation. Your second task is to observe the driver’s exit and walk from the vehicle.

19. PHASE THREE Your first task is to administer structured, formal psychophysical tests. Based on these steps, you must decide whether there is sufficient probable cause to arrest the driver for DUI. Your second task is then to arrange for (or administer) a Preliminary Breath Test (if applicable.)

20. DUI DETECTION PHASE ONE: VEHICLE IN MOTION Your first task in phase one is to observe the vehicle in operation to note any initial cues of a possible DUI violation. The first task, begins when you first notice the vehicle, driver or both. Your attention may be drawn to the vehicle by such things as: 1. A moving traffic violation. 2. An expired registration or inspection sticker. 3. Unusual driving actions, such as deviating within a lane or moving at slower than normal speed 4. An equipment violation. 5. “Evidence of drinking” or drugs in vehicle. (Transporting an Open Container)

21. Based upon this initial observation of the vehicle in motion, you must decide whether there is probable cause to stop the vehicle. At this point you have three choices: 1. Stop the vehicle. 2. Continue to observe the vehicle 3. Disregard the vehicle DUI DETECTION PHASE ONE: VEHICLE IN MOTION CONTINUED

22. INITIAL OBSERVATIONS: VISUAL CUES TO DUI. Drivers who are under the influence of alcohol, drugs or both frequently exhibit certain effects or symptoms of impairment. These include: A. Slowed reactions B. Impaired judgement as evidenced by a willingness to take risks C. Impaired vision D. Poor coordination

23. DIVIDED ATTENTION It is important to understand the effects of alcohol are exhibited in driving so that the significance of visual cues will be recognized. Driving is a complex task involving a number of subtasks, many of which occur simultaneously. These include: 1. Steering 2. Controlling the accelerator 3. Signaling 4. Controlling the brake pedal 5. Operating the clutch 6. Operating the gearshift 7. Observing other traffic 8. Observing signal lights, stop signs and other traffic control devices 9. Making decisions (Whether to stop, turn, speed up, or slow down.)

24. RECOGNIZING AND DESCRIBING INITIAL CUES Observing the vehicle in operation is the first task in DWI/DUI detection. Proper performance of that task requires two distinct but related abilities. 1. The ability to recognize evidence of alcohol or drug influence. 2.The ability to describe that evidence clearly and convincingly. It is not enough that you observe and recognize symptoms of impaired driving. You also must be able to describe what happened so that others will have a clear mental picture of what took place.

25. THE STOPPING SEQUENCE Cues reinforcing the suspicion of DWI/DUI may be found in the stopping sequence. After the command to stop is given, the alcohol-impaired driver may exhibit additional important evidence of DWI/DUI. These cues may include: 1. An attempt to flee 2. No response 3. Slow response 4. An abrupt swerve 5. Sudden stop 6. Striking the curb or another object Some of these cues come to light because the stop command places additional demands on the driver’s ability to divide attention. The signal to stop creates a new situation with which the driver must cope.

26. PHASE TWO: PERSONAL CONTACT/FACE-TO-FACE The first task of phase two is observation and interview of the driver, begins as soon as the suspect vehicle and the patrol vehicle have come to a complete stop. It continues through your approach to the suspect vehicle and involves all conversation between you and the driver prior to the driver’s exit from the vehicle. Regardless of the evidence that may have come to light during detection phase one, your initial face-to-face contact with the driver usually provides the first definite indications that the driver is under the influence.

27. Typical investigation clues: The driver interview face to face observation and interview of the driver allows you to use three senses to gather evidence of alcohol or drug influence. 1. Sense of smell. 2. Sense of sight. 3. Sense of hearing.

28. SIGHT There are a number of things you might see during the interview that would be describable clues or evidence of alcohol or drug influence 1. Blood shot eyes 2. Soiled clothing 3. Fumbling fingers 4. Alcohol containers 5. Drugs or drug paraphernalia 6. Bruises, bumps, or scratches 7. Unusual actions

29. HEARING Among the things you might hear during the interview that would be describable clues or evidence of alcohol or drug influence. 1. Slurred speech 2. Admission of drinking 3. Inconsistent responses 4. Abusive language 5. Unusual statements

30. SMELL There are things you might smell during the interview that would be describable clues or evidence of alcohol or drug influence. 1. Odor of alcoholic type beverages 2. Marijuana 3. “Cover up” odors i.e. Breath sprays or Cologne 4. Unusual odors

31. PRE-EXIT SOBRIETY TESTS There are a number of simple tests of impairment you can administer to a driver while the driver is still behind the wheel. Most of these simple tests apply the concept of divided attention; they require the driver to concentrate on two or more things at the same time. The tests include both question and answer tests and psychophysical tests.

32. QUESTION AND ANSWER TESTS The questions you ask and the way in which you ask them can constitute simple divided attention tests. Three techniques are particularly pertinent: 1. Ask for two things simultaneously 2. Ask interrupting or distracting questions 3. Ask unusual questions

33. An example of the two things simultaneously is requesting that the driver produce both the driver’s license and the vehicle registration. Be alert for the driver who: 1. Forgets to produce both documents 2. Produces documents other than the ones requested 3. Fails to see the license, registration or both while searching through wallet or purse 4. Fumbles or drops wallet, purse, license or registration 5. Unable to retrieve documents using fingertips

34. The 2nd technique, asking interrupting/distracting questions forces the driver to divide attention between searching for the license or registration and answering a new question. While the driver is responding to the request for license, registration or both, you ask an unrelated question like, “Without looking at your watch, can you tell me what time it is right now?” Be alert for the driver who: 1. Ignores the question and concentrates only on the license or registration search. 2. Forgets to resume the search after answering the question. 3. Supplies a grossly incorrect answer to the question.

35. The third technique, asking unusual questions is employed after you have obtained the driver’s license and registration. Example, while holding the driver’s license, you might ask the driver, “What is your middle name?” There are many such questions which the driver normally would be able to answer easily, but which might prove difficult if the driver is impaired, simply because they are unusual questions.

36. BEHIND THE WHEEL PSYCHOPHYSICAL TESTS Psychophysical tests are divided attention tests. Behind the wheel psychophysical tests may include the alphabet, count down, and finger count tests. These field tests of a driver’s mental and physical impairment are often administered outside the vehicle, but they can be given while the driver is still inside the vehicle. Whenever these tasks are given, you should provide clear instructions and, if possible demonstrate what the driver should do.

37. ALPHABET TEST The alphabet test requires the subject to recite a part of the alphabet. You instruct the subject to recite the alphabet beginning with a letter other than A and stopping at a letter other than Z. This divides the driver’s attention because the driver must concentrate to begin at an unusual starting point and recall where to stop.

38. COUNT DOWN TEST The count down test requires the subject to count out loud 15 or more numbers in reverse sequence. This divides attention because the driver must continuously concentrate to count backwards while trying to recall where to stop. This test should never be given using starting and stopping points of 0 or 5 because these numbers are too easy to recall.

39. FINGER COUNT TEST In this test, the subject is asked to touch the tip of his right thumb in turn to the tip of each finger on the right hand while simultaneously counting up one, two, three, four; then reverse direction on the fingers while simultaneously counting down.

40. THE EXIT SEQUENCE Your decision to instruct the driver to step out of the vehicle usually is made only after you have developed a definite suspicion that the driver is under the influence. SAFETY NOTE You may instruct a suspect to exit the vehicle as a means of ensuring your own safety. Safety considerations take precedence over all other considerations. Even though that suspicion may be very strong, usually the suspect is not yet under arrest when you give the instruction.

41. How the driver steps and walks from the vehicle and actions or behavior during the exit sequence may provide important evidence of alcohol or drug influence. Be alert for the driver who: 1. Shows angry or unusual reactions 2. Can not follow instructions 3. Can not open the door 4. Leaves the vehicle in gear 5. “Climbs” out of the vehicle 6. Leans against the vehicle 7. Keeps hands on the vehicle for balance THE EXIT SEQUENCE

42. PHASE THREE: PRE-ARREST SCREENING Your first task in phase three is to administer structured formal psychophysical (Field) sobriety tests. Based on these tests and on all other evidence from phase one and two, you must decide whether there is sufficient probable cause to arrest the driver for DUI. Your second task may then be to administer (or arrange for) a preliminary breath test (PBT) to confirm the chemical basis of the driver’s impairment, if your agency uses PBT’s. The entire detection process culminates in the arrest/no arrest decision.

43. Prior to administering any field sobriety tests, ask the suspect: 1. Are you on or have you taken medication that impairs your ability to take this test? 2. Do you have a physical disability that will preclude you from taking this test?

44. WALK AND TURN: Walk and turn is a test that has been validated through extensive research sponsored by the National Highway Traffic Safety Administration (NHTSA). It is a divided attention test consisting of two stages: 1. Instructional Stage 2. Walking Stage

45. In the Instructional Stage the subject must stand on a line with feet in a heel-to-toe position, keep arms at sides, and listen to the instructions. The instructional stage divides the subject’s attention between a balancing task (standing on the line while maintaining the heel-to-toe position) and an information processing task (listening to and remembering instructions.)

46. In the Walking stage the subject must take nine heel-to-toe steps down the line, turn in a prescribed way, and take nine heel-to-toe steps up the line, while counting the steps out loud. During the turn, the subject must keep one foot on the line, pivot on that foot, and use the other to take several small steps to complete the turn. The walking stage divides the subject’s attention among a balancing task (Walking heel-to-toe and turning on the line); a small muscle control task (counting out loud); and a short-term memory task (recalling the number of steps and the turning sequence).

47. The Walk and Turn test is administered in a standard fashion, i.e., the same way every time. It is also interpreted in a standardized fashion. Specifically, officers administering Walk and Turn carefully observe the suspect’s performance for eight clues: 1. Can’t balance during the instructions 2. Starts too soon 3. Stops while walking 4. Doesn’t touch heel-to-toe 5. Steps off the line 6. Uses arms to balance 7. Loses balance on turn or turns incorrectly 8. Takes the wrong number of steps

48. ONE-LEG STAND The One-leg stand test also has been validated through NHTSA’s research program. It is a divided attention test consisting of two stages: 1. Instructional Stage 2. Balancing and Counting Stage

49. In the Instructional Stage, the suspect must stand with feet together, keep arms at sides, and listen to the instructions. This divides the subject’s attention between a balancing task (maintaining a stance) and an information processing task (listening to and remembering instructions).

50. In the Balancing and Counting Stage, the subject must stand on one foot and hold the other foot straight out approximately six inches off the ground, while staring at the upraised foot and counting aloud from “one thousand and one” to “one thousand and thirty”. This divides the subject’s attention between balancing (standing on one foot) and small muscle control (counting out loud).

51. The count to “one thousand and thirty” is an important part on the One-leg stand test. Research has shown that many impaired subjects are able to maintain one leg balance for up to 25 seconds, but that relatively few can do so for 30 seconds.

52. One-leg stand is also administered and interpreted in a standardized fashion. Officers carefully observe suspects’ performance and look for four specific clues: 1. Sways while balancing 2. Uses arms to balance 3. Hops 4. Puts foot down

53. POST DRIVING PRIVILEGES All persons charged with drunk driving (DWI/DUI) on Fort Bliss and those persons charged with drunk driving offenses off- post, will have their post driving privileges suspended for one year prior to being released from Military Police control. After notification of an off post offense, and all post offenses, all personnel charged with drunk driving will have their post decal confiscated and retained on DA FM 4137.

54. NOTE TAKING AND TESTIMONY A basic skill needed for DWI/DUI enforcement is the ability to graphically describe your observations. Just as detection is the process of collecting evidence, description largely is the process of conveying evidence. Successful description demands the ability to convey evidence clearly and convincingly. Your challenge is to communicate evidence to people who weren’t there to see, hear, and smell the evidence themselves. Your tools are the words that make up your written report and verbal testimony. You must communicate with the supervisor, the prosecutor, the judge, the jury, and even with the defense attorney. You are trying to “paint a word picture” for those people, to develop a sharp mental image that allows them to “see” what you saw; “hear” what you heard; and “smell” what you smelled.

55. INVESTIGATIVE FIELD NOTES One of the most critical tasks in the DWI/DUI enforcement process is the recognition and retention of facts and cues that establish probable cause to stop, investigate and subsequently arrest persons suspected of driving or operating a vehicle while under the influence of alcohol, drugs or both. The evidence gathered during the detection process must establish the elements of the violation, and must be documented to support successful prosecution of the violator. This evidence is largely sensory (sight, smell, and hearing) in nature, and therefore is extremely short-lived.

56. COURTROOM TESTIMONY Although only a minority of DWI/DUI cases actually comes to trial, the arresting officer must be fully prepared to testify in court on any case. Testimonial evidence in DWI/DUI cases usually is the only way to establish that the accused was in fact the driver of the vehicle alleged to have been involved in the DWI/DUI incident. Testimonial evidence also may be the primary and sometimes the only means of establishing that the accused was intoxicated, or under the influence of alcohol or drugs. Even when scientific evidence is available, supportive testimonial evidence will be required to permit introduction of that scientific evidence in court.
