Are Field Sobriety Tests Always Accurate?
When a person is stopped under the suspicion that they have been driving
while intoxicated, a law enforcement officer will likely request that
the driver step out of the vehicle and perform a series of
field sobriety tests. This type of sobriety testing is made up of three standardized tests—including
the Walk & Turn, the One-Leg Stand, and the Horizontal Gaze Nystagmus.
These tests are designed to give an officer a more accurate idea of whether
or not the driver's physical and/or cognitive functions have been
impaired by alcohol consumption or the use of a controlled substance.
The accuracy of these tests is often under debate, however, because several
other factors may affect the results of the test—including environmental
factors, fatigue, physical impairment, body weight, etc.
Despite the potential inaccuracy, a law enforcement officer may arrest
a driver for DWI depending on the driver's performance on these tests
and other observations that the officer has made in regard to the driver's
behavior. The arresting officer would then take the driver back to the
police station, where he or she may face a urine and/or blood test to
blood alcohol concentration. The outcome of the breath, blood, and field sobriety tests along with
the arresting officer's testimony are likely going to be the primary
evidence. Challenging this evidence will therefore be an important part
of the defense argument that your lawyer provides. Field sobriety tests
are not always accurate. So, if you have any doubt that a law enforcement
officer incorrectly administered the test or unfairly judged your performance,
you should go over the facts of your arrest with a local attorney.
Questioning the Validity of Evidence
When challenging DWI evidence, your defense attorney may look for violations
of procedure or your constitutional rights that were potentially committed
by law enforcement personnel. A procedural violation may be a simple mistake
or deviation from standard procedure in regard to the administration or
grading of a test. For example, a breath test device that is not properly
calibrated may give inaccurate results. The same may apply if proper procedure
is not followed when a law enforcement officer is instructing a driver
to take a field sobriety test. Your lawyer may be able to bring these
issues to light.
A violation of your constitutional rights may also offer your attorney
grounds to challenge evidence that was gathered against you. The arresting
officer may have lacked probable cause to arrest you for DWI or to pull
you over in the first place. Also, the officer may have forgotten to read
you your Miranda rights, which is a major violation. If you do not understand
your rights, you will not be able to discern whether or not they have
been violated, so do not hesitate to go over the facts of your arrest
with an attorney as soon as you have been charged with a crime.
Are Chemical Tests Always Accurate?
When referring to a
DWI case, a chemical test such as a
breath test, blood test or urine test may be administered in order to determine the presence and
amount of alcohol or controlled substances in a driver's system. The
results of these tests often provide the foundation for the government's
case against a driver who has been charged with drunk driving or driving
under the influence of drugs. Though a failed breathalyzer test or blood
test may make it seem as though there is no hope of avoiding a conviction,
there are various ways that an attorney who is experienced with challenging
DWI evidence can contest chemical test results to fight a client's charges.
A qualified lawyer can thoroughly review the circumstances that led up
to the driver's chemical testing, the device used to administer the
test, the person that conducted the test, the test results, and the procedure
of the test itself. An independent analysis of a blood sample may reveal
that the results were skewed or that the sample was mixed improperly with
anticoagulants or preservatives. A review of the maintenance of a breathalyzer
device may show that it was improperly calibrated. By conducting a complete
investigation into every aspect of chemical tests, a competent attorney
can locate even the smallest opportunity of weakening the prosecution's
case against a defendant.
About DWI Tests
Breath and blood tests are most frequently administered in DWI cases. Urine
tests are typically only used in limited circumstances, either related
to the use of drugs while driving or cases where a breath or blood sample
cannot be given for medical reasons. With a complete understanding of
how these tests operate and experience in the field of DWI defense, our
legal team can provide you with the aggressive representation you need
in the face of allegedly failed or refused chemical tests.
