FIELD SOBRIETY EVALUATIONS OR "TESTS"
GENERALLY
Motorists suspected of DUI / DWI are routinely asked by police officers
to perform one or more field sobriety exercises. These
voluntary "tests" (yes, voluntary) were developed by police
agencies to assist law enforcement officers in making roadside determinations
as to whether a motorist is under the influence of alcohol or drugs.
Through the performance of these tests or evaluations, the officer
subjectively determines how the motorist reacts to and performs
the requested tasks.
Almost EVERY knowledgeable DUI / DWI attorney will say to you, "NO.
Don't attempt ANY 'field tests'---EVER." That is because
many studies have concluded that the SFSTs are "designed to fail".
A motorist's alleged poor performance on field evaluations may provide
the "probable cause" (legal justification) an officer needs to arrest
a person for impaired driving and may also become part of the proof
used to later convict the person at trial. See Parrish v. State,
216 Ga. App. 832, 456 S.E.2d 283 (1995). Therefore, it is very important
that, in defending you, your defense attorney know as much or more
about these tests as the police, if he or she is going to defend
you.
One sure way to know that your attorney is up to date: is your lawyer
"NHTSA certified"? Certified as a "student"? Or certified
as an "instructor". Ask him/her. This training has been
available to defense attorneys since 1994, and over 1000 attorneys
nationwide have received the training. Mr. Head is an SFST
instructor, and has taught or helped teach these evaluations to
over 300 other defense lawyers.
Counsel for the defense should
challenge the subjective nature of the evaluations, the accuracy
of the principles behind the tests, the accuracy of the administration
of the tests, the credibility of the officer who "requested" the
tests, and challenge all circumstances connected with the evaluations.
The attorney representing you must attack the factual and legal
issues that may arise regarding the officer's scoring and evaluation
of the field tests.
Only three tests have
been "scientifically" studied (in lengthy studies paid for by the
federal government) and represented to have any measure of reliability
in helping an officer predict whether a subject is above a certain
legal limit (0.10 BAC, in the original testing). These tests,
known as the "standardized field sobriety tests" [SFSTs], were designed
pursuant to numerous federal grants and ultimately sanctioned by
NHTSA (the National Highway Traffic and Safety Administration) beginning
in 1984. These three tests are (1) the walk and turn [WAT]
test, (2) the one leg stand [OLS] test, and (3) the horizontal gaze
nystagmus [HGN] test. However, the manuals (plural
here, because 6 separate versions have now been released)
say that if not performed properly, or if conducted without adhering
to the training protocols, such actions "compromise" the validity
of these evaluations.
Starting in the 1970's, NHTSA began studying and funding "field
tests" to see if any of the dozens of police exercises had any correlation
to showing if a drinking driver had a blood alcohol level of 0.10
grams percent or higher. The "studies" determined that only
the three named evaluations had any reliable correlation better
than 50-50 (flipping a coin and guessing 'heads', being a 50-50
reliability test, for example) to identify a person having a BAC
of 0.10% or more. These evaluations in no way
were used to determine whether a driver is impaired . . . only whether
the person may be 0.10 or more.
The HGN evaluation, when performed correctly on proper subjects,
had a 77% "claimed" reliability rating. The WAT exercise,
when conducted properly on a qualified subject on a dry, level surface,
was found to be 68% reliable. The OLS exercise, when conducted
properly, on a qualified subject on a level, dry surface and under
proper instructions and where correctly demonstrated and scored,
reportedly yields about 65% reliability. Cumulatively, if
all are done correctly, up to 83% correlation to a BAC of 0.10%
or more may be expected.
Knowledgeable criminal defense lawyers know that 98% or more of
the officers administering these evaluations do them wrong, or
conduct them in a manner (or on a test subject) not approved by
the SFST manual, or grade the evaluations improperly,
as per the manual, or ALL OF THE ABOVE. When
done incorrectly, these evaluations have ZERO predicted
reliability. Hence, a top-notch DUI/DWI lawyer can cross-examine
the arresting officer using his/her OWN training materials that
the federal government and YOUR state government have approved.
Recent research and scientific review of the testing protocols and
scoring methodology have brought the NHTSA "Standardized Field Sobriety
Tests ("SFSTs") into serious question. Courts across America
are taking a closer look at the original research, to see if proper
scientific methods were employed in the initial research.
More and more courts are now saying "no" to these questions.
In a recent New Mexico case, a high-level court has declared that
the person who "developed" the tests (Dr. Marcelline Burns) was
not qualified to testify as an expert witness about the scientific
principles behind the HGN test. (Lasworth v. State,
42 P.2d 844 (N.M. App. 2001).)
HISTORIC ROOTS
Prior to the 1980's and NHTSA's studies on field testing, police
officers across America were taught a wide variety of "tests" to
be given to persons stopped for suspected drunk driving. Most of
these "tests" had never been studied to determine "fairness" or
accuracy in detecting either impaired drivers or drivers who were
operating a vehicle while their BAC level was 0.10 BAC or more.
Moreover, no standardized method (that is, not being done the same
way by officers who used these tests) of scoring or grading these
tests had been attempted. Simply stated, the decision to arrest
was based upon the subjective whim of the officer. Mistakes
were made in a large percentage of cases.
Tests given by some officers may have included reciting the alphabet
(or a portion thereof), picking up coins off the ground, or touching
index fingers to the tip of the nose while the person's eyes were
closed and head tilted back. Some involved strange, one-legged tapping
on the roadway with a raised foot (similar to what that famous television
horse, Mr. Ed, used to do). These "made-up" tests were administered
to subjects without any scientific or empirical basis for reliability
in detecting an impaired driver. These tests were designed for failure,
not for fairness. Even worse, police officers often forced
people to perform these voluntary evaluations, thereby violating
these citizens' rights.
Some "non-standardized" tests were so ridiculous and difficult that
proof of non-validity was easy with almost any jury or judge. Today,
officers who lack NHTSA training invariably cannot cite any studies
or scientific research which "validated" their tests, the scoring
(e.g., "pass" or "fail") or their testing methods. Almost always,
no scoring system is used on tests which do not adhere to NHTSA
guidelines. If non-standardized tests are used, the number of errors
that are required for a subject to fail is totally subjective with
each officer. Hence, the untrained officer is usually an easy target
for a skilled and knowledgeable criminal defense attorney who knows
the "limitations" of these field tests.
THE ISSUE OF THE ``SCIENCE'' OF FIELD
TESTING
A great rift exists among scientific experts on the question of
whether field sobriety tests are ``scientific.'' For example, Georgia's
appellate courts have blown hot and cold on this subject.
Torrance v. State, 217 Ga. App. 562, 458 S.E.2d 495 (1995);
Manley v. State, 206 Ga. App. 281, 424 S.E.2d 818 (1992);
Foster v. State, 204 Ga. App. 632, 420 S.E.2d 78 (1992);
Crawford v. City of Forest Park, 215 Ga. App. 234, 450 S.E.2d
237 (1994) [holding that field tests given by the arresting officer
were not ``a scientific procedure,'' but ``simply a behavioral observation
on the officer's part'']; Hassell v. State, 212 Ga. App.
432, 442 S.E.2d 261 (1994); Hawkins v. State, 223 Ga. App.
34, 476 S.E.2d 803 (1996). Challenges to field sobriety tests based
upon proof of a scientific foundation by an expert have been rejected
by the court of appeals. Druitt v. State, 225 Ga. App.
150, 483 S.E.2d 117 (1997). See also Padgett v. State,
230 Ga. App. 659, 498 S.E.2d 84 (1998), where the court of appeals
held that field sobriety tests are merely dexterity exercises and
the word ``tests'' is a misnomer.
The reason that most credible scientists across America (and in
other countries) are unwilling to categorize field tests -- even
NHTSA's tests -- as being "scientific" is that too many variables
are involved in roadside testing to ever eliminate pure chance and
non-controlled circumstances from the equation (e.g., environmental
conditions such as lighting and roadway slope). Numerous states,
including Texas, Alabama and Mississippi, do not permit HGN evidence
to be admitted at trial. The reason behind this is that these
"party games" (as noted Swedish scientist Dr. A.W. Jones has called
them) do not pass well-established rules f evidence (the court rules
for determining when certain types of information may be told to
the jury) for scientifically acceptable tests.
Even NHTSA admits that under optimal conditions (i.e., in an air-conditioned,
well lighted room) 35% of sober, drug-free subjects get inaccurate
results on the one leg stand test, 32% of sober subjects get flawed
results on the walk and turn, and 23% of sober subjects are inaccurately
said to be "over the legal limit" on the horizontal gaze nystagmus
test. By comparison, polygraph (lie detector) tests are more than
90% accurate when conducted by a qualified operator), and (absent
a stipulation by both parties) are still not permitted into evidence
by most courts.

THESE
ARE VOLUNTARY TESTS
Only a small number of states have tried to pass laws to make the
field tests not be 100% voluntary. These states typically
will assess a monetary fine against someone who says "no" to these
voluntary tests. So what? I tell all my fiends
and relatives and clients: DON'T ATTEMPT THESE TESTS.
Other states have said that the State Constitution provides that
no person can be compelled to take such tests.
Case law in virtually all U.S. jurisdictions indicates that if a
person is being detained or is "in custody," no field tests can
be given without first providing Miranda advisements (i.e.,
right to remain silent; right to an attorney; if you can't afford
an attorney, one will be appointed for you). State v. O'Donnell,
225 Ga. App. 502, 484 S.E.2d 313 (1997). Hence, the new focus
for defense attorneys is to establish that some sort of ``custody''
or detention has occurred prior to the field tests. See
also Price v. State, 269 Ga. 222, 498 S.E.2d 262 (1998).
However,
many appellate courts have bent over backward to ignore clear signs
of custody. For example, despite guns being drawn on a driver,
the Georgia Court of Appeals (in Hassell v. State---see citation
above) ruled that this was not "custody". Of course,
this is a ridiculous ruling, but part of "Georgia law," regardless.
Other
courts have stood tall and said "if NHTSA tests are supposed to
be scientific, then they must be done correctly". The
previously mentioned Lasworth case from the New Mexico Court
of Appeals is just such a case.
The
Supreme Court of Ohio recently held that the officer's failure to
follow NHTSA training in administering field sobriety exercises
was a factor in determining the admissibility of the test. State
v. Homan, 732 N.E.2d 952 (Ohio 2000). In Homan, a NHTSA‑trained
officer's admitted failure to administer the field sobriety exercises
in strict compliance with NHTSA's standardized testing procedures
invalidated (and excluded) all of the State's evidence about the
field sobriety exercises. The Homan court made the following
findings regarding the unreliability of field tests not conducted
in compliance with NHTSA procedure:
When field sobriety testing is conducted in a manner that departs
from established methods and procedures, the results are inherently
unreliable. In an extensive study, the National Highway Traffic
Safety Administration ("NHTSA") evaluated field sobriety tests in
terms of their utility in determining whether a subject's blood‑alcohol
concentration is below or above the legal limit. The NHTSA concluded
that field sobriety tests are an effective means of detecting legal
intoxication "only when: the tests are administered in the prescribed,
standardized manner[,] . . . the standardized clues are
used to assess the suspect's performance[, and] . . .
the standardized criteria are employed to interpret that performance."
National Highway Traffic Safety Adm., U.S. Dept. of Transp., HS
178 R2/00, DWI Detection and Standardized Field Sobriety Testing,
Student Manual (2000), at VIII‑3. According to the NHTSA,
"[i]f any one of the standardized field sobriety test elements is
changed, the validity is compromised." Id. Experts in the
areas of drunk driving apprehension, prosecution, and defense all
appear to agree that the reliability of field sobriety test results
does indeed turn upon the degree to which police comply with standardized
testing procedures. See, e.g., 1 Erwin, Defense
of Drunk Driving Cases (3 Ed.1997), Section 10.06[4]; Cohen &
Green, Apprehending and Prosecuting the Drunk Driver: A Manual for
Police and Prosecution (1997), Section 4.01.
ROADSIDE ALCOHOL SCREENING TESTS
A portable breath testing device may be used by police officers
in determining whether or not a motorist is under the influence
of alcohol. Some states have banned the use of these voluntary "non-evidential"
screening devices. "Non-evidential" means that "the digital
number" can't be used against you in court. Some states have
ruled that the only place at trial that these can be used is at
a pre-trial hearing at which "probable cause" for arrest is involved.
Like other "field tests", these
devices are used at the roadway. Often, police officers do
not regularly check the devices for calibration. Furthermore,
the manufacturer's instructions (e.g., failing to observe a 15 minute
deprivation period, waiting at least 4 minutes between tests, or
clearing the prior test results) for proper use are routinely ignored.
Some states have started using these roadside testers as evidential
tests. This is accomplished when a small printer is attached
to the breath test apparatus. Unless your state uses such
a device as an OFFICIAL state-mandated breath test, no person should
ever submit to these devices and risk a false positive result and
almost certain arrest. Politely DECLINE to give this voluntary
sample, if it is not the official state test.
THE NEWEST "VOODOO" SCIENCE: THE "DEC" PROGRAM TO IDENTIFY DRUG
USE
Government studies have revealed that many drivers are under the
influence of drugs, or a combination of alcohol and drugs. To combat
this, an effort has been mounted since the early 1990's to add some
type of training to the police officer's arsenal that will assist
in identifying drug-impaired individuals. Hence, NHTSA has created
the ``Drug Evaluation and Classification'' (DEC) Program.
A DEC officer does not typically work in the field (i.e., making
traffic arrests), or make the initial arrest of an impaired driver.
A DEC officer is called in after a subject either shows a low score
on an alcohol test, or otherwise 'smells' like or 'acts' like he/she
has been using drugs. The proper procedure is for the DEC
officer to give Miranda warnings to the person (already in custody),
and then start "the evaluation for drug usage". SIMPLE
RULE: SAY NO! You have just been told of
your constitutional rights---USE THEM! Say nothing and do
nothing beyond say, "I'd like to speak to an attorney." More
information on Your Constitutional Rights.
The function of DEC is to ascertain:
(a) Whether the person is impaired by something;
(b) If impaired, is it from drugs as opposed
to alcohol;
(c) If the impairment appears to be from drugs,
what ``manifestations'' or visible indicia of impairment would
indicate the TYPE or CATEGORY of drug being used?
As opposed to trying to target a single ``impairing'' chemical,
the DEC process seeks to ``recognize'' indications of any of seven
broad categories of drugs:
(1) Central nervous system depressants, such
as Valium, Xanax or alcohol;
(2) Central nervous system stimulants (e.g.,
crack or powder cocaine);
(3) Hallucinogens, such as L.S.D.;
(4) Phencyclidine, such as P.C.P. (which can
manifest itself as a stimulant, depressant or hallucinogen, and
is highly unpredictable);
(5) Inhalants, such as glues or other aerosol
products, which block the passage of oxygen to the brain;
(6) Narcotic analgesics, such as Demerol, Dilaudid,
opium, heroin, Methadone and other powerful pain relievers; and
(7) Cannabis (marijuana and its ``family'' of
psychoactive plants.)
The hope of the police is that
these DEC evaluations can be used in court to identify impairment
from drugs even if the person refuses all blood and urine testing.
Absent a blood or urine test or an admission of recent drug use,
"opinion" testimony must be based upon something more than a wild
guess or speculation. Ironically, NHTSA designed the DEC Program
for post-arrest investigation, to be done in a carefully controlled
environment (as opposed to "field" evaluation).
Numerous "task force" officers across America have taken IACP-approved
DEC classes to enable them to identify a subject impaired by drugs.
IACP is the acronym for International Association of Chiefs
of Police. Sometimes referred to as "DREs" or "DRTs" (drug
recognition experts or drug recognition technicians),
these officers utilize a series of simple evaluations and observations
to help them identify individuals impaired by drugs.
Interestingly, even the IACP recognizes the limitations of the DEC
program. For example, the agency recognizes that DEC-trained officers
cannot identify exactly what drug (or drugs) a person is "on."
Only one of the seven broad "categories" listed might be identified,
if the person has been fully trained and certified. IACP has
emphasized the need for an analytical chemical test to confirm the
officer's "suspicions" about drug use. This is because anything
less than a chemical test is just "an educated GUESS". The
law does not support guesswork in criminal trials, because
the State must prove guilt BEYOND A REASONABL DOUBT.
The DEC process includes an alcohol screening evaluation on a roadside
screening device such as an Alco-Sensor. It also includes administering
the NHTSA standardized field sobriety tests. The twelve components
of the DEC process include:
(1) A breath alcohol screening test to determine
an estimated BAC level;
(2) Interviewing the arresting officer, to see
what was seen or heard in earlier contact;
(3) The preliminary examination, including questions
to determine pre-existing injury, or the existence of a health
or mental condition that may mimic drug use;
(4) Eye examination, using both horizontal and
vertical nystagmus tests, plus checking to see if the eyes converge
properly;
(5) Divided attention tests, including walk and
turn, one-leg stand, finger to nose and the Romberg balance test;
(6) Vital signs examination, checking pulse rate,
blood pressure and temperature;
(7) Dark room examination, including measurement
of pupil size, reaction of the eyes to light and tell-tale evidence
of ingestion of drugs by nose or by mouth;
(8) Examination of muscle tone -- Depending on
the type of drug used, muscles can be rigid or flaccid. Examination
is performed from the bicep to the wrist;
(9) Looking for injection sites, (i.e., needle
marks or "tracks") on the arms, neck, legs, etc.;
(10) Questioning the suspect -- After giving
all the required "constitutional and statutory" advisements, ask
the subject questions concerning the drug or drugs suspected to
be involved;
(11) The opinion of the DEC evaluator is used
to summarize the "findings" and to fill out reports designed to
document the observed facts which support the officer's conclusions;
and
(12) A toxicological examination to provide scientific,
admissible evidence to substantiate the DEC evaluator's conclusions.
(This assumes that a person submits to the test offered, where
an option to NOT do so exists.)
A properly equipped DEC officer will have these items with him or
her:
(a) blood pressure kit;
(b) an electronic aneroid thermometer;
(c) a pupillometer (to measure the size of the
subject's pupils);
(d) a preliminary alcohol screening device, such
as an Alco-Sensor; and
(e) access to a dark room.
The DEC protocol teaches officers
to not only look for either contraband (illegal) or controlled substances
(i.e., those drugs which cannot be purchased without a prescription),
but to take note of over-the-counter medications that the subject
has ingested which may have caused or contributed to the suspect's
impairment. Certain allergy and cold medicines have been determined
by the American Medical Association and FDA to be particularly unsafe
for persons who are driving. These include Benadryl, Allerdryl,
Contac Severe Cold Formula, Vicks Nyquil, Trifed, Phenergan and
others.
Although the use of DEC evaluations by "DRE" officers requires extensive
training, this is a wave of the future. Decisions in several states
have upheld DEC evaluations by DRE officers, utilizing both a Daubert
analysis and a Frye analysis of admissibility. Daubert
and Frye are well-known federal cases that have carved out
the rules of when and after what type of judicial review scientific
evidence can be admitted at a trial. About 45 of the 50 states follow
one standard or the other. See State v. Klawitter,
518 N.W.2d 577 (Minn. 1994) [using a Daubert analysis] and
People v. Quinn, 580 N.Y.S.2d 818 (Suffolk County Dist. Ct.
1991), rev'd and remanded on other grounds, 607 N.Y.S.2d
534 (Sup. Ct. App. Term 1993) [using a Frye analysis].
See State v. Sampson, 6 P.3d 543 (Or.App. 2000) for
a fascinating analysis of prior DEC admissibility in various states.
As with other "pro-prosecution" types of "scientific" evidence,
expect courts to overrule objections to DEC evaluations based on
highly discretionary trial court review of "proper" evidence.
The need of the State to "make our highways safe" will likely outweigh
the "voodoo" nature of the DEC "opinion" evidence. The best hope
for the defense is that a fair-minded judge will look at the highly
irregular nature of this evidence and declare "the State has not
laid a proper foundation for this scientific evidence. Therefore,
this evidence is excluded."
