DUI Tests
Drunken driving related arrests form one of the major portions
of total number of arrests made in the United States and
elsewhere. As more people are found to drunk while driving their
vehicles, a need was felt among the police department to set up
some tests to make ascertain that there was an incidence of
drunken driving involved. Such tests also assured that the
arresting officer had enough evidence on his hand to prove that
there was indeed an incident of drunken driving. Several tests
and exams are carried out to check drunken driving and its
effects. While detecting drunken drivers is very easy in some
circumstances such as heavy and uncontrolled drunkenness, this
is not really easy when the person has very little influence of
alcohol. However, irrespective of the state of drunkenness,
authorities have formulated five clear cut ways by which an
arresting officer can run some tests on the erring driver. Also
called DUI tests, these series of tests are also known as Field
Sobriety Test. There are five known methods of gathering
evidence in a drunken driving case. The simplest way by which an
incidence of drunken driving can be tested is by checking the
driving pattern of the driver. A typical drunken driver usually
drives the car by jumping the lane or by erratic driving.
Surprisingly, these drivers are not excess speed violators while
they are drunk. The second method is to identify all those
telltale signs of drunkenness like bloodshot eyes, thick and/or
slurred speech, flushed face, fumbling with a wallet to get the
driver's license, unsteady gait, leaning on the car for support
and difficulty following directions. Some of the most famous
field sobriety tests that are conducted by the arresting officer
are walk-and-turn, touch-the-nose, one-leg-stand, horizontal
gaze nystagmus (following an object like a pen or finger from
side-to-side with your eyes), fingers-to-thumb and hand pat.
Many arresting officers are also using a roadside breath-testing
device called Breath Analyzer. Called as Preliminary Alcohol
Screening units, these instruments give a rough indication blood
alcohol concentration. Though this test is not reliable, some
agencies still use this test. Police officer can also ask many
incriminating questions and statements to the suspects. However
the suspect is not really required to answer those incriminating
statements. The last type of the DUI test is chemical test that
checks either the blood or breath to check for the residues of
alcohol. However, even this test is sometimes very unreliable
and legally untenable. The residue that is checked for alcohol
is the methyl group of the alcohol that is consumed.
