DUI Science; there are only three standardized field sobriety tests

Extensive government testing was begun in the 1970's to determine a scientifically valid way of helping police officers detect intoxication in drivers under suspicion of drunk driving.  The National Highway Traffic and Safety Administration (NHTSA) guidelines were set up to help make these tests more accurate. After extensive testing, NHTSA determined that three tests were specific for alcohol intoxication: the HGN (horizontal gaze nystagmus), the walk & turn test and the one leg stand test. They are now called ‘standardized field sobriety tests.Many officers rely upon other tests to determine intoxication.  These tests may include:The Rhomberg stationary balance test wherein...

Standardized Field Sobriety Tests; the walk & turn

A metal detector can detect guns.  Does that mean that every person who sets off the metal detector has a gun?  The standardized field sobriety tests can detect lack of coordination due to intoxication.  Does that mean that all lack of coordination is indicative of intoxication?  Here a completely sober person fails the Walk & Turn portion of the standardized field sobriety tests.  If you think that you have been wrongly labled as intoxicated contact Dayton DUI Defense Attorney Charles M. Rowland II at 937-318-1DUI (318-1384).Completely sober person fails Walk & Turn...

Ohio OVI Law – a definition

Image via WikipediaThe term OVI (Operating a Vehicle while Impaired) is the latest acronym for the universally understood DUI; they mean the same thing.  Often you will find yourself charged with OVI offenses in two ways: the first is for testing over the per se limit, and the second charge for operating a vehicle while impaired. In Ohio driving under the influence includes driving while intoxicated with too much alcohol, or driving under the influence of a drug of abuse. The traditional offense is "driving under the influence of alcohol" (DUI). Ohio has also enacted a second, so-called "per se"...

DUI Arrests Based on Nontestimonial Evidence

TESTIMONIAL vs. NONTESTIMONIALImage via WikipediaIn Pennsylvania v. Muniz, 110 S.Ct.2638 (1990), the United States Supreme Court held that slurred speech and the muscle coordination (or lack thereof) required to complete the standardized field sobriety tests amount to nontestimonial information that does not fall within the scope of the Fifth Amendment privilege against self-incrimination and does not invoke the safeguards of Miranda warnings.  They held that standardized field sobriety tests are "real" tests and/or tests of a "physical" variety.  This ruling was consistent with its holding in Schmerber v. California, 384 U.S. 757 (1966), which held that the Fifth Amendment...

What are the standardized field sobriety tests?

Image via WikipediaThe standardized field sobriety tests consist of a three-test battery which includes a check of your eyes (called the horizontal gaze nystagmus test, or HGN), and two tests of your coordination, balance, stamina and memory called the one-leg stand test and the walk and turn test.  Officers use these tests to establish probable cause for a drunk driving arrest. The tests are set forth in the National Highway Transportation Safety Administration manual, which is used to train law enforcement in administering the tests.  The DUI defense team of Charles M.

Preface to the 2006 NHTSA Manual

Preface to the 2006 Standardized Field Sobriety Test (NHTSA) Manual The procedures outlined in this manual describe how the Standardized Field Sobriety Tests (SFSTs) are to be administered under ideal conditions. We recognize that the SFSTs will not always be administered under ideal conditions in the field, because such conditions will not always exist. Even when administered under less than ideal conditions, they will generally serve as valid and useful indicators of impairment. Slight variations from the ideal, i.e., the inability to find a perfectly smooth surface at roadside, may have some affect on the evidentiary weight given to the results. However, this does not necessarily make the...
