A. Overview Tasks and Decisions
DWI Detection Phase Two: Personal Contact, like Phases One and Three, comprise
two major evidence gathering tasks and one major decision. Your first task is to
approach, observe, and interview the driver while they are still in the vehicle to Note any
face to face evidence of impairment. During this face to face contact you may administer
some simple pre-exit sobriety tests to gain additional information to evaluate whether or
not the driver is impaired. After this evaluation, you must decide whether to request the
driver to exit the vehicle for further field sobriety testing. In some jurisdictions,
departmental policy may dictate that all drivers stopped on suspicion of DWI be
instructed to exit. It is important to Note that by instructing the driver to exit the vehicle,
you are not committed to an arrest; this is simply another step in the DWI detection
process. Once you have requested the driver to exit the vehicle, your second task is to
observe the manner in which the driver exits and to Note any additional evidence of
impairment.
You may initiate Phase Two without Phase One. This may occur, for example, at a
checkpoint, or when you have responded to the scene of a crash.

Task One
The first task of Phase Two, interview and observation of the driver, begins as soon as
the driver vehicle and the patrol vehicle have come to complete stops. It continues
through your approach to the driver vehicle and involves all conversation between you
and the driver prior to the driver's exit from the vehicle.
You may have developed a strong suspicion that the driver is impaired prior to the face
to face observation and interview. You may have developed this suspicion by observing
something unusual while the vehicle was in motion, or during the stopping sequence.
You may have developed no suspicion of DWI prior to the face to face contact. The
vehicle operation and the stop may have been normal; you may have seen no actions
suggesting DWI.
For example, you may have stopped the vehicle for an equipment/registration violation,
or where no unusual driving was evident. In some cases, Phase One will have been
absent. For example, you may first encounter the driver and vehicle after a crash or
when responding to a request for motorist assistance.
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 impaired.

Decision
Based upon your face to face interview and observation of the driver, and upon your
previous observations of the vehicle in motion and the stopping sequence, you must
decide whether there is sufficient reason to instruct the driver to step from the vehicle.
For some law enforcement officers, this decision is automatic since their agency’s policy
dictates that the driver always be told to exit the vehicle, regardless of the cause for the
stop. Other agencies; however, treat this as a discretionary decision to be based on
what the officer sees, hears, and smells during observation and interview with the driver
while the driver is seated in the vehicle.
If you decide to instruct the driver to exit, closely observe the driver's actions during the
exit from the vehicle and Note any evidence of impairment.

B. Typical Investigation Clues of the Driver Interview
Face to face observation and interview of the driver allows you to use three senses to
gather evidence of alcohol and/or other drug influence:
• The sense of sight
• The sense of hearing
• The sense of smell
