Phase Two: Personal Contact DWI Detection and Standardized Field Sobriety Testing Requires the ability to: • Recognize the sensory evidence of alcohol and/or other drug influence

Session 6-Phase Two: Personal Contact

DWI Detection and Standardized Field Sobriety Testing

Requires the ability to:

• Recognize the sensory evidence of

alcohol and/or other drug influence

• Describe that evidence clearly and

convincingly

Phase Two: Task One

Face to Face Observation and

Interview of Suspect

6-13

Proper face to face observation and interview of the driver demands two distinct but

related abilities:

• The ability to recognize the sensory evidence of alcohol and/or other drug influence

• The ability to describe that evidence clearly and convincingly

Developing these abilities requires practice.

C. Recognition and Description of Investigation Clues

A basic purpose of the face to face observation and interview of the driver is to identify

and gather evidence of alcohol and/or other drug influence. This is the purpose of each

task in each phase of DWI detection.

During the face to face observation and interview stage, it is not necessary to gather

sufficient evidence to arrest the driver immediately for DWI.

Procedures for Practicing Clue

Recognition and Description

6-14

Procedures for Practicing Clue Recognition and Description

You will have to base your description of the driver's possible impairment strictly on what

you see and hear during the face to face contact.

Both senses provide some critically important evidence, not only in this video segment,

but in all face to face contacts.

questions

• Asking unusual questions

Interview/Questioning Techniques

6-16

D. Interview/Questioning Techniques

There are a number of techniques you can use to assess impairment while the driver is

still behind the wheel. Most of these techniques apply the concept of divided attention.

They require the driver to concentrate on two or more things at the same time. They

include both questioning techniques and psychophysical (mind/body) tasks.

These techniques are not as reliable as the Standardized Field Sobriety Tests but they

can still be useful for obtaining evidence of impairment. THESE TECHNIQUES DO NOT

REPLACE THE SFSTs.

Questioning Techniques

The questions you ask and the way in which you ask them can constitute simple divided

attention tasks. Three techniques are particularly pertinent:

• Asking for two things simultaneously

• Asking interrupting or distracting questions

• Asking unusual questions.

An example of the first technique, asking for two things simultaneously, is requesting

the driver to produce both the driver's license and the vehicle registration. Possible

evidence of impairment may be observed as the driver responds to this dual request.

Session 6-Phase Two: Personal Contact

DWI Detection and Standardized Field Sobriety Testing

• Forgets to produce both documents

• Produces wrong documents

• Fails to see the license, registration or

both while searching for them

• Fumbles or drops wallet, purse, license

or registration

• Unable to retrieve documents using

fingertips

License and Registration

6-17

Be alert for the driver who:

• Forgets to produce both documents

• Produces documents other than the ones requested

• Fails to see the license, registration or both while searching for them

• Fumbles or drops wallet, purse, license or registration

• Is unable to retrieve documents using fingertips

Session 6-Phase Two: Personal Contact

DWI Detection and Standardized Field Sobriety Testing

• What day is it?

• Where are you coming from?

• Be alert for the driver who:

• Ignores the question and concentrates only on the

license or registration search

• Forgets to resume the search after answering the

question

• Supplies a grossly incorrect answer to the question

Questions that Divide Attention

6-18

The second technique would be to ask questions that require 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 unrelated questions; "What day is it?” or “Where are you coming from?”

Possible evidence of impairment may be disclosed by the actions of the driver after this

question has been posed. Be alert for the driver who:

• Ignores the question and concentrates only on the license or registration search

• Forgets to resume the search after answering the question

• Supplies a grossly incorrect answer to the question
