Count Down
This
technique requires the driver to count out loud 15 or more numbers in reverse
sequence.
For example, you might request a driver to, "Count out loud backwards,
starting
with the number 68 and ending with the number 53." This, too, divides
attention
because
the driver must continuously concentrate to count backwards while trying to
recall
where to stop.

Additional Techniques

Finger Count
In
this technique, the driver is asked to touch the tip of the thumb to the tip of
each
finger
on the same hand while simultaneously counting up one, two, three, four; then
to
reverse
direction on the fingers while simultaneously counting down four, three, two,
one.
In
each instance, Note whether and how well the driver is able to perform the
divided
attention
task.

E. Recognition and Description of Clues Associated With the Exit Sequence
Your
decision to instruct the driver to step from the vehicle usually is made after
you
have
developed a suspicion that the driver is impaired. Even if that suspicion may
be
very
strong, the driver is usually not under arrest when you give the instruction.
How
the driver steps and walks from the vehicle and actions or behavior during the
exit
sequence
may provide important evidence of impairment. Be alert to the driver who:
Proper
face to face observation and interview of a driver requires the ability to
recognize
the
sensory evidence of alcohol and/or other drug influence and the ability to
describe
that
evidence clearly and convincingly. Developing these abilities takes practice.
