DUI Lawyer - Common Field Sobriety Tests for Lenawee County 2A OWI cases

Here are the three tests, which are in the NHSTA manual, which we must address. 

Walk and turn test

This test requires a defendant to walk heel to toe and turn.  The officer is required to find a clean surface with a visible line; the surface must be level.  It is VERY easy to fail this test; most sober people cannot 100 percent comply with its requirements.  If you lose balance, start early, end early, fail to touch heel to toe on each step, usage arms for balance, stepping off the visible line or performing incorrect number of steps, you fail this test.  This is not a reliable test for intoxication, and your attorney will explore the results of this test on cross-examination.

One-legged stand

The arresting officer will instruct the defendant to stand with a leg raised about six inches off the ground for about 30 seconds.  If the defendant sways, hops or uses his/her arms for balance, it's a failure.  This is a ridiculous test for most people, and almost impossible for person with physical conditions or defendants of certain age groups.  Your attorney will explore the results of this test, and go after the assumption that the results of this test are any bit reliable.

Horizontal Gaze Nystagmus

This is a test that looks for involuntary jerking of the eye, which is alleged to be caused by the presence of alcohol in the defendant's system.  This test is highly subjective, which the officers have very little training.  An officer is expected to conduct an eye examination on the side of the road, and determine whether the subject has consumed alcohol based upon jerking of an eye.  You don't need to be a doctor to know that jerking of an eye can be caused by various reasons other than alcohol consumption.
