Want to have some fun at the next party or BBQ you host? Set up some DUI
Field Sobriety Exercise stations for your friends and get out your video
camera. You don’t even need alcohol.
Last week in Part 1 of this blog on what everyone needs to know about DUI,
we discussed how a DUI investigation typically begins in one of two ways:
- A law enforcement officer stops a vehicle when he believes the driver is
impaired (i.e. after watching the vehicle swerve, fail to stay in a single
lane and / or some other driving pattern which gives the officer a reasonable
suspicion the driver is impaired), or
- An officer stops a vehicle for a traffic offense (i.e. speeding, running
a stop sign or a headlight being out), and while speaking with the driver
the officer notices signs of impairment like slurred speech, bloodshot,
glassy eyes, trouble following directions or finding items requested by
the officer (license, registration and proof of insurance) and the smell
If the officer observes some of these, or other, signs of impairment exhibited
by a driver that officer may temporarily detain the driver to perform
a DUI investigation. Today we will pick up from there and assume that
the officer is moving forward with their DUI investigation and has asked
you to get out of your car and perform a series of field sobriety exercises.
Fact: I have reviewed thousands of DUI reports in my career in criminal
law and have not seen a single report where the officer determined that
the person performed the field sobriety exercises “satisfactorily”
as required. There is a rumor that a gymnast from the University of Florida
was able to perform them, but I have not personally seen that report.
Given those worse than Vegas odds, if it is me, I remain seated in my car,
looking straight ahead, with my hands on the steering wheel and my mouth
shut. (See part 1 of this blog if you missed it.) Knowing that all of
you may not take this advice and because you still need to know how to
set up your field sobriety exercise stations for your friends, I will
tell you about the most common exercises used and how they are supposed
to be performed.
St. Augustine DUI Attorney Explains Field Sobriety Tests
In theory, Field Sobriety Exercises supposedly can be performed by the
average person and are designed to either confirm or dispel an officer’s
suspicions that a person is driving under the influence. In actuality,
these exercises involve complicated and unnatural tasks that are difficult
for many people to perform, regardless of whether they have been drinking.
Further, the person being investigated is usually required to perform
these exercises under less than ideal conditions, such as on the side
of a road, in a dark parking lot, or even wearing flip flops. Add that
everyone performing the exercises knows the stakes and is nervous and
a bad situation just got worse.
In Florida, four types of FSEs are typically used (also referred to as
- The horizontal gaze nystagmus (or HGN)
- The walk and turn
- The finger to nose, and
- The one legged stand
Station 1 – Bouncing Pupils
HGN is an exercise where the person investigated stands with their arms
at their side and their head still and is asked to follow a stimulus (usually
a light or pen) using only their eyes. The stimulus is then moved horizontally
as the officer observes the person’s eyes. The officer watches the
person’s eyes looking for “the onset of nystagmus”.
In layman’s terms, nystagmus is a sort of “bouncing”
of the pupil and it occurs naturally when the pupil is ninety degrees
from the center of the eye in either direction. Nystagmus will be present
in a person who is impaired by alcohol prior to the pupil reaching ninety
degrees from center, and a trained officer will be able to tell a great
deal of information regarding a person’s impairment depending on
when that officer first observes nystagmus (for example, at sixty degrees
instead of ninety). Some people have natural nystagmus, so see if any
of your friends fall into that category.
Station 2 – Walk and Turn
The second commonly used FSE is the walk and turn. During this exercise
the person is asked to stand heel to toe (one foot in front of the other)
at the beginning of a line with their arms at their side. Try just doing
this part; it isn’t as easy as it sounds. The person is then instructed
to take nine steps, staying on the line and touching their heel to the
toe of their other foot, while counting out loud and keeping their arms
by their sides. Did you get all those instructions? Just wait, there are
more. After taking nine steps the person is instructed to turn around
using an awkward series of small steps and take nine heel to toe steps
back down the line still keeping their arms at their sides. I just fell
of the line on step 4 and quit. The officer is looking for you to do anything
wrong: Beginning too early; stepping off the line; taking the incorrect
number of steps; raising your arms; and, asking them to clarify the instructions.
All of which will be counted against you in their report.
Station 3 – Finger to Nose
Make sure the video camera is ready for this one. During this exercise
the officer instructs the person to stand with their feet together and
their arms outstretched like a cross. The person is then told to tilt
their head back and close their eyes. The officer will then say “right”
or “left”, and the person must then touch the tip of their
nose using the tip of their index finger on their left or right hand.
After touching the tip of their nose the person is to return their arms
back out to their starting position. Again, starting too soon, not touching
the absolute tip of the nose with the absolute tip of the index finger,
swaying, moving your feet apart for balance, opening your eyes, are all
counted against you.
Station 4 – One Leg Stand
As the name indicates, during this exercise a person is asked to stand
on one leg for a specified amount of time. This exercise begins with the
person standing with their feet together and their hands at their side.
When instructed by the officer, the person is to raise their foot off
the ground six to eight inches, while pointing their toe, and focusing
their eyes on the tip of their toe. They are then instructed to count
to thirty beginning “one one thousand, two one thousand” until
reaching “thirty one thousand”. See how far you can get without
putting your foot down or raising your arms to help balance. Any balance
bobble or sway is counted against you, as are all the other common mistakes
Are field sobriety tests reliable?
In a well-lit, level, parking lot, without the nerves and wearing your
cross fit shoes, how well can you perform the exercises sober? What about
after 3 drinks, which for the average person is still below the legal
limit? You can see now why the odds are so stacked against someone “passing”
the field sobriety exercises. Worse yet, their performance just gave the
prosecutor more evidence to convict them with if the case goes to trial.
Jury members are told that they are not to conduct any investigation on
their own, and I don’t condone jury members breaking the rules.
That said, I have to tell this quick story. While I was still in law school
a close family member found themselves selected to sit on a criminal DUI
jury. The driving wasn’t that bad and the person had refused the
breath test. The crux of the case came down to the field sobriety exercises.
This family member listened as the officer described how the exercises
were to be performed and how the defendant had failed to complete them
as instructed and demonstrated. The prosecutor followed up with a demand
that a guilty verdict be returned. When the jury went in to deliberate
my family member excused themselves to the restroom. They then tried to
perform the field sobriety exercises as the officer said they needed to
be performed. Needless to say, they could not come close and returned
to deliberations to advocate for a not guilty verdict. We must do what
we can to protect ourselves because we cannot all count on a juror like
this to point out the flaws in the system that stacks the deck so substantially
against someone accused of DUI.
Should you agree to do the field sobriety exercises?
I had one case where the officer asked my client to do one final field
sobriety exercise. He had him stand with his feet together, hands relaxed
at his sides, eyes closed, and head tilted back. Then he placed him in
handcuffs. My experience as a criminal defense attorney suggests that
no matter how athletic you are, or how little you have had to drink, this
too will be your fate if you find yourself to the point of doing field
Admittedly, you will probably be arrested if you refuse to perform the
field sobriety exercises. But at least you haven’t given the State
more evidence to use against you. But what about having the prosecutor
rail on you at trial to the jury that your refusal to perform the field
sobriety exercises shows a consciousness of guilt; that you knew you were
drunk and so didn’t want to perform? I would love to hear someday
that the defendant’s response was that they read a blog one time
written by an experienced DUI attorney and had actually tried to perform
the field sobriety exercises personally and with a group of friends and
that none of them could do them as required, without even drinking a drop
Preview of Part 3
Whether or not you chose to perform the field sobriety exercises you now
find yourself arrested for DUI. Do you take the breath test? Next week
we will discuss this issue as we finish up with what everyone needs to
know about DUI.
