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.

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.
