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.

Recognition and Description

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.

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
