Conditional Dismissal and Fingerprinting in NJ

Law Enforcment Torch Run 2014

Kenneth Vercammen and Metuchen Police Officers participated in the New Jersey Law Enforcement Torch Run 2014.

DWI Detection and Field Sobriety Testing- Section 5 Phase One

At the conclusion of this session, participants will be able to:

•       Identify typical cues of Detection Phase One

•       Describe the observed cues clearly and convincingly

The first task, observing the vehicle in motion, begins when you first notice the vehicle, driver or both. Your attention may be drawn to the vehicle by such things as:

•       A moving traffic violation

•       An equipment violation

•       An expired registration or inspection sticker

•       Unusual driving actions, such as weaving within a lane or moving at a slower than normal speed

•       Evidence of drinking or drugs in vehicle

If this initial observation discloses vehicle maneuvers or human behaviors that may be associated with impairment, you may develop an initial suspicion of DWI.

Based upon this initial observation of the vehicle in motion, you must decide whether there is reasonable suspicion to stop the vehicle. At this point you have three choices:

•       Stop the vehicle.

•       Continue to observe the vehicle. • Alternatives to stopping the vehicle include:

•       Delaying the stop/no stop decision, in order to continue observing the vehicle

•       Disregarding the vehicle

This unit focuses on alcohol impairment because research currently provides more information about the effects of alcohol on driving than it does about the effects of other drugs on driving.  Remember that whether the driver is impaired, the law enforcement detection process is the same, and the offense is still DWI.

The common effects of alcohol on the driver's mental and physical faculties lead to predictable driving violations and vehicle operating characteristics. The National Highway Traffic Safety Administration (NHTSA) sponsored research to identify the most common and reliable initial indicators of DWI. This research identified 24 cues, each with an associated high probability that the driver exhibiting the cue is impaired. These cues and their associated probabilities are described in the NHTSA publication,

The Visual Detection of DWI Motorists.

They also are discussed in Visual Detection of Driving While Intoxicated, a video sponsored by NHTSA to assist law enforcement officers to recognize DWI detection cues.

(ANACAPA Sciences, DOT HS 808 654, 1997.)

The National Highway Traffic Safety Administration sponsored research to identify the most common and reliable initial indicators of DWI.

Research identified 100 cues, each providing a high probability indication that the driver is under the influence.

The list was reduced to 24 cues during three field studies involving hundreds of officers and more than 12,000 enforcement stops.

Relationship of Visual Cues to Impaired Divided Attention Capability

Driving is a complex task, composed of many parts:

•       Steering

•       Controlling accelerator

•       Signaling

•       Controlling brake pedal

•       Operating clutch (if applicable)

•       Operating gearshift (if applicable)

•       Observing other traffic

•       Observing signal lights, stop signs, other traffic control devices

•       Making decisions (whether to stop, turn, speed up, slow down, etc.)

•       Many other things

In order to drive safely, a driver must be able to divide attention among all of these various activities.

Under the influence of alcohol or many drugs, a person's ability to divide attention becomes impaired.

The impaired driver tends to concentrate on certain parts of driving and to disregard other parts.

•       Alcohol has impaired ability to divide attention.

•       Driver is concentrating on steering and controlling the accelerator and brake.

•       Does not respond to the particular color of the traffic light.

Some of the most significant evidence from all three phases of DWI detection can be related directly to the effects of alcohol and/or other drugs on divided attention ability.

D. Recognition and Description of Initial Cues

What do you see?

•       Moving violation?

•       Equipment violation?

•       Other violation?

•       Unusual operation?

•       Anything else?

Phase One: Task One Initial Observation of Vehicle Operation

Requires the ability to:

•       Recognize evidence of alcohol and/or other drug influence

•       Describe that evidence clearly and convincingly

Standard zed Fie d Sobr ety Test ng

Phase One: Task One Initial Observation of Vehicle Operation

The task of making initial observations of vehicle operation is the first step in the job of DWI detection.

Proper performance of that task demands two distinct but related abilities:

•       Ability to recognize evidence of alcohol and/or other drug influence.

•       Ability to describe that evidence clearly and convincingly.

It is not enough that a police officer observe and recognize symptoms of impaired driving. The officer must be able to articulate what was observed so that a judge or jury will have a clear mental image of exactly what took place.

Improving the ability to recognize and clearly describe observational evidence requires practice.

It isn't practical to have impaired drivers actually drive through the classroom.

The next best thing is to use video to portray typical DWI detection contacts.

Procedures for Practicing Cue Recognition and Description

•       View DWI violation videos

•       Take notes

•       Testify

•       Choose words carefully

•       Provide as much detail as possible

•       Construct accurate image of observations

•       Critique testimony

E. Typical Reinforcing Cues of the Stopping Sequence

After the command to stop is given, the alcohol impaired driver may exhibit additional important evidence of DWI.

Some of these cues are exhibited because the stop command places additional demands on the driver's ability to divide attention.

The signal to stop creates a new situation, to which the driver must devote some attention, i.e., emergency flashing lights, siren, etc., demand and divert the subject's attention.

Signal to stop requires the driver to turn the steering wheel, operate the brake pedal, activate the signal light, etc.

As soon as officer gives the stop command, the subject's driving task becomes more complex.

If subject is under the influence, the subject may not be able to handle this more complex driving very well.

DWI Detection and Field Sobriety Testing- Section 4 Detection, Note Taking, And Testimony

Learning Objectives

• Three phases of detection
• Tasks and key decision of each phase
• Uses of a standard note taking guide
• Guidelines for effective testimony
• Conduct a thorough pre-trial review of all evidence and prepare for testimony
• Provide clear, accurate and descriptive direct testimony concerning drug influence evaluations

Upon successfully completing this session the participant will be able to:

• Describe the three phases of detection.
• Describe the tasks and key decision of each phase.
• Discuss the uses of a standard note taking guide.
• Discuss guidelines for effective testimony.

Detection is both the most important and difficult task in the DWI enforcement effort.  If officers fail to detect DWI offenders, the DWI countermeasures program will ultimately fail. If officers do not detect and arrest DWI offenders, then prosecutors cannot prosecute them, the courts and driver licensing officials cannot impose sanctions on them, and treatment and rehabilitation programs will go unused.

DWI Detection

• The entire process of identifying and gathering evidence to determine if a subject should be arrested for a DWI violation.

The term DWI detection has been used in many different ways.  Consequently it does not mean the same thing to all law enforcement officers.  For the purposes of this training, DWI detection is defined as: The entire process of identifying and gathering evidence to determine if a subject should be arrested for a DWI violation.

Detection begins when the officer develops the first suspicion of a DWI violation.

Detection ends when the officer decides whether or not there is sufficient probable cause to arrest the driver for DWI. Your attention may be called to a particular vehicle or individual for a variety of reasons. The precipitating event may be a loud noise, an obvious equipment or moving violation, behavior that is unusual, but not necessarily illegal, or almost anything else.  Initial detection may carry with it an immediate suspicion that the driver is impaired; or a slight suspicion; or even no suspicion at all.  In any case, it sets in motion a process wherein you focus on a particular vehicle or individual and have the opportunity to observe that vehicle or individual and to gather additional evidence.

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

on Note Taking and Test mony

DWI Detection Phases

• Phase One – Vehicle in Motion
• Phase Two – Personal Contact
• Phase Three – Pre-Arrest Screening

A. Three Phases of Detection

The typical DWI 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 Standardized Field Sobriety Tests to the driver to determine impairment.

In addition to SFSTs, some jurisdictions may allow you to administer other field sobriety tests, and/or a preliminary breath test (PBT) to verify that alcohol is the cause of the impairment. PBTs can be used to assist in making an arrest decision and should rarely be the only factor in deciding to arrest.  PBTs should be used after administering SFSTs.

on Note Taking and Test mony

The DWI detection process does not always include all three phases. Sometimes there are DWI detection contacts in which Phase One is absent. These are cases in which you have no opportunity to observe the vehicle in motion. This may occur at the crash scene, at a roadblock or checkpoint, or when you have responded to a request for motorist assistance. Sometimes there are DWI contacts in which Phase Three is absent. There are cases in which you would not administer formal tests to the driver. This may occur when the driver is grossly impaired, badly injured, or refuses to submit to tests.

Decisions and Possible Outcomes Decisions

• Phase One -Stop?
• Phase Two -Exit?
• Phase Three -Arrest? Possible Outcomes
• Yes – Do it now
• Wait – Look for more evidence

In each of the three phases, there will be decisions and possible outcomes.

Test mony

Decisions

• Phase One: Vehicle in Motion – Should I stop the vehicle?
• Phase Two – Personal Contact -Should the driver exit?
• Phase Three – Pre-arrest Screening -Is there probable cause to arrest the suspect for DWI?

Major Tasks and Decisions

Each detection phase usually involves two major tasks and one major decision.

• In Phase One: Your first task is to observe the vehicle in operation. 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. You may want to take a picture of the vehicle or scene, especially if the vehicle was involved in a crash.
• In 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. You may want to take a photo of the defendant.
• In Phase Three: Your first task is to administer structured, formal psychophysical tests. Based on these tests, you must decide whether there is sufficient probable cause to arrest the driver for DWI. Your second task is then to arrange for (or administer) a Preliminary Breath Test.

Possible Outcomes Yes – Do It Now

• Phase One: Yes, there are reasonable grounds to stop the vehicle
• Phase Two: Yes, there is enough reason to suspect impairment to justify getting the driver out of the vehicle for further investigation
• Phase Three: Yes, there is probable cause to arrest driver for DWI right now

Each of the major decisions can have any one of three different outcomes:

• Yes -Do it Now
• Wait -Look for Additional Evidence
• No -Don't Do It

Consider the following examples.

Yes -Do It Now

Phase One: Yes, there are reasonable grounds to stop the vehicle.

Phase Two: Yes, there is enough reason to suspect impairment to justify getting the driver out of the vehicle for further investigation.

Phase Three: Yes, there is probable cause to arrest the driver for DWI right now.

Possible Outcomes Wait – Look for Additional Evidence

• Phase One: Don't stop the vehicle yet; keep following and observing it longer
• Phase Two: Don't get the driver out of the car yet; keep talking to and observing the driver longer
• Phase Three: Don't arrest the driver yet; administer another field sobriety test before deciding

Wait -Look for Additional Evidence

• Phase One: Don't stop the vehicle yet; keep following and observing it a bit longer.
• Phase Two: Don't get the driver out of the car yet; keep talking to and observing the driver a bit longer. (This option may be limited if the officer's personal safety is at risk.)
• Phase Three: Don't arrest the driver yet; administer another field sobriety test before deciding.

Possible Outcomes No – Don’t do it

• Phase One:  No, there are no grounds for stopping that vehicle
• Phase Two:  No, there isn't enough evidence of DWI to justify administering field sobriety tests
• Phase Three: No, there is not sufficient probable cause to believe this driver has committed DWI

Don't Do It:

• Phase One:  No, there are no grounds for stopping that vehicle.
• Phase Two:  No, there isn't enough evidence of DWI to justify administering field sobriety tests.
• Phase Three:  No, there is not sufficient probable cause to believe this driver has committed DWI.

Officer Responsibility

In each phase of detection, you must determine whether there is sufficient evidence to establish the "reasonable suspicion" necessary to proceed to the next step in the detection process.  It is always your duty to carry out whatever tasks are appropriate, to make sure that ALL relevant evidence of DWI is gathered.

Detect on Note Taking and Test mony

DWI Detection – Phase One

Phase Three:

• Should I administer field sobriety tests to the driver?
• How does the driver perform those tests?
• What exactly did the driver do wrong when performing the tests?
• Do I have probable cause to arrest for DWI?

Successful DWI Detection

• Know what to look and listen for
• Ask the right kinds of questions
• Choose and use the right kinds of tests
• Make, interpret, and document all observations thoroughly
• Be motivated and apply your knowledge and skill whenever you encounter someone who may be under the influence

The most successful DWI detectors are those officers who:

• Know what to look and listen for
• Ask the right kinds of questions
• Choose and use the right kinds of tests
• Make, interpret, and document all observations thoroughly
• Are motivated and apply their knowledge and skill whenever they encounter someone who may be under the influence

Note Taking and Testimony

• Graphically describe your observations
• Convey evidence clearly and convincingly
• Field notes are only as good as the information they contain

Sobriety Testing

Note Taking and Testimony

A basic skill needed for DWI 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 or articulating 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.

Officers with the knowledge, skills and motivation to select the most appropriate words for both written reports and courtroom testimony will communicate clearly and convincingly, making them more successful in DWI prosecution.

 Field Sobriety Testing

Use Clear and Convincing Language

Field notes are only as good as the information they contain.  Reports must be clearly written and events accurately described if the reports are to have evidentiary value. One persistent problem with DWI incident reports is the use of vague language to describe conditions, events and statements. When vague language is used, reports provide an inaccurate picture of what happened.  Clear and complete field notes help in preparation for your testimony.

B. DWI Investigation Field Notes

One of the most critical tasks in the DWI enforcement process is the recognition and retention of facts and clues that establish reasonable suspicion to stop, investigate and subsequently arrest persons suspected of DWI. The evidence gathered during the detection process must establish the elements of the violation, and must be completely documented to support successful prosecution of the defendant. This evidence is largely sensory (sight, smell, hearing) in nature, and therefore is extremely short lived.

You must be able to recognize and act on the facts and circumstances with which you are confronted.  But you also must completely document your observations and describe them clearly and convincingly to secure a conviction. You may be inundated with evidence of DWI, i.e., sights, sounds, smells. You recognize this evidence, sometimes subconsciously, and on this evidence base your decisions to stop, to investigate and ultimately to arrest.

Since evidence of a DWI violation is short lived, you need a system and tools for recording field notes at scenes of DWI investigations.

Session 4 Overv ew of Detect on Note Taking and Test mony

One way to improve the effectiveness of your handwritten field notes is to use a structured note taking guide. The guide makes it easy to record brief "notes" on each step of the detection process and ensures that vital evidence is documented.

The field notes provide the information necessary to complete required DWI report forms and assist you in preparing a written account of the incident. The field notes will also be useful if you are required to provide oral testimony, since they can be used to refresh your memory.

A model note taking guide is provided for your use. A brief description follows.  Details are provided in subsequent units.

Note Taking Guide

Remember that you must document those actions which gave you reasonable suspicion or probable cause to justify further investigation of a suspected DWI incident.

Section V provides space to record the officer's general observations, such as the subject's manner of speech, attitude, clothing, etc. Any physical evidence collected should also be noted in this section.

Since this is a note taking guide and space is limited, you will have to develop your own "shorthand" system. Your notes should be detailed and descriptive of the facts, circumstances or events being described. These notes may be used to refresh your memory and to write the narrative report documenting your observations to testify in court.

NOTE:  Field notes may be subpoenaed as evidence in court.  It is important that any "shorthand" system you use be describable, usable, complete and consistent.

Preparing Testimony At time of incident:

• Recognize significant evidence
• Compile complete, accurate notes
• Prepare complete, accurate, detailed report

C. Courtroom Testimony

Testimonial evidence in DWI cases establishes that the defendant was in fact the driver and was under the influence. Your testimony should be clear, detailed, and concise. Requirements: Preparation at the scene and prior to trial.

To be effective, testimonial evidence must be clear and convincing. The first requirement for effective testimony is preparation. Testimony preparation begins at the time of the DWI incident.  From the very beginning of the DWI contact, it is your responsibility to:

Recognize significant evidence

Compile complete, accurate field notes

Prepare a complete, accurate, detailed report

Preparing Testimony (Cont.)

Prior to trial:

• Review all paperwork
• Review all other evidence
• Mentally organize elements and evidence
• Mentally organize testimony
• Identify potential issues
• Discuss with prosecutor

DWI Detection and Standardized Field Sobriety Testing

Testimony preparation continues prior to trial. Just before the trial, you should:

• Review field notes, incident report, narrative and other paperwork
• Review other evidence, i.e., video, photographs, etc.
• Mentally organize elements of offense, and the evidence available to prove each element
• Mentally organize testimony to convey observations clearly and convincingly
• Identify weak spots and/or potential issues with the case and decide how to address those issues
• Discuss the case with the prosecutor

The foundation for preparation and successful testimony is the relationship between the law enforcement officer(s) involved with the arrest and the prosecuting attorney(s) associated with the case.  Effective communication and a clear understanding of each groups’ objectives and expectations is essential for successful prosecution.
