DUI Tests
By Cave Mark
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.
