Field Sobriety Tests in MO DWI Arrests
What do you need to know about this DWI evidence?
Field sobriety tests are one of the ways that a St. Louis police officer
that has pulled over a driver on suspicion of driving under the influence
can gather evidence to make an arrest.
YOU ARE NOT REQUIRED BY LAW TO SUBMIT TO A FIELD SOBRIETY TEST. In nearly every DWI case, the police officer has already made up their
mind whether or not they will try and make an arrest, and the purpose
of a field sobriety test is to simply justify that decision. Don’t
let police officers bully you into something you are not legally required
An experienced DWI lawyer will try to have the results of field sobriety
tests suppressed in court for a number of reasons. Many police officers
are not properly trained to administer and/or properly evaluate the results
of a field sobriety test. These tests are largely subjective and are often
conducted in non-ideal conditions.

What are field sobriety tests?
Field sobriety tests are comprised of physical and mental tasks used to
determine if the driver is impaired. The
National Highway Transportation Safety Administration (NHTSA) has recommended specific instructions on which field sobriety
tests should be conducted and how a police officer should conduct the
tests. The NHTSA has stated that "If any one of the standardized
field sobriety test elements is changed, the validity is compromised."
The NHTSA recommends the following standardized field sobriety tests:
The Horizontal Gaze Nystagmus (HGN) Test: Asking the accused to follow an object, such as a pen, with their eyes
in order to observe the involuntary reaction of the eyes at certain angles.
The Walk-and-Turn (WAT) Test: The suspected drunk driver is asked to walk heel to toe in a straight
line and return in the same manner.
The One-Leg-Stand Test: A driver is asked to hold one foot off the ground and count by thousands
for around 30 seconds.
According to some estimates, these tests, when used in combination with
one another, are allegedly accurate in 91% of all DWI cases. If this estimation
is correct, it is also assuming that the tests were performed correctly
and there were no extenuating circumstances that could have contributed
to a false positive.
In addition to these tests, many police officers will ask a driver suspected
of drunk driving to recite the alphabet without singing and/or to count
backwards from 100 to a specific number. These tests are not endorsed
by the NHTSA as part of a standardized field sobriety test rotation.
