A Drug Recognition Expert (DRE) will use four divided attention psychophysical
tests to evaluate someone suspected of
drug impairment. These tests are standardized in their administration, documentation,
and interpretation. This is very important because it means it has to
given exactly the same way each time: same instructions, always recording
the subject’s performance in a prescribed manner; and looking for
a specific set of cues to determine to what extent the subjects are impaired.
The next few blogs will examine each test in detail. The four tests are
listed in the proper sequence:
• Romberg Balance
• Walk and Turn
• One Leg Stand
• Finger to Nose
Both the Walk and Turn and the One leg Stand are scientifically validated
which means that they were subjected to controlled research, in which
hundreds of drinkers volunteered, and showed that a DRE could see the
difference between sober and drunk drivers. The Romberg Balance and Finger
to Nose tests have not been subjected to scientific validity. What this
means is that any mistake the DRE makes in administering these tests can
be used to
create a defense. These tests are subjective in nature even though two have been scientifically
validated, the tests are not the only thing taken into consideration to
determine the sobriety of a subject.
