How Do Chemical Tests Affect DWI Cases?
Blood tests and breath tests are forms of chemical testing that are used
to determine whether individuals were driving while intoxicated. After
being pulled over by a law enforcement officer for suspected drunk driving,
the driver will usually be required to blow into a portable breathalyzer.
This device gives a reading of the driver's blood alcohol concentration
(BAC), allowing the officer to determine whether the BAC is at or above
the legal limit. If the driver is arrested, he or she will likely be required
to submit to additional breath testing and/or a blood testing at the station.
For drivers who are suspected of driving while intoxicated by drugs, blood
tests are used since breath tests do not work in the same way for these
types of cases.
Problems that Can Lead to False Test Results
There are strict protocols that must be followed when administering blood
and breath tests and analyzing the results. When law enforcement officers
and medical personnel do not follow all of these requirements, they can
end up compromising the validity of these tests.
Common problems with breath tests include the failure to properly maintain
or calibrate the testing equipment, mechanical errors in breathalyzer
devices, the failure to obtain a sufficient breath sample or higher readings
triggered by certain products used by the test taker (such as cough medicine).
For blood tests, common problems include mistakes made while drawing blood,
improper storage of blood samples, failure to test the blood sample in
a timely manner and blood sample mix-ups. A knowledgeable
criminal defense attorney in Sugar Land can help you determine what types of defenses you
may be able to use in your case.
