Sobriety Testing in Ohio

Sobriety Testing for Serious Vehicular Crimes in Ohio

Sobriety tests sometimes play a role in cases of Vehicular Homicide and Vehicular Assault in Columbus, Ohio and the central Ohio area. When law enforcement officers investigate a driver for Vehicular Assault or Vehicular Homicide, the officers may come to suspect the driver is under the influence of alcohol and/or drugs. If so, and if the driver is medically able, the officers administer Field Sobriety Tests. If drugs are suspected, an officer may also administer a Drug Recognition Evaluation. This page provides information on sobriety testing for Vehicular Homicide and Vehicular Assault in Ohio.

When one of these cases involves an allegation the driver was under the influence of alcohol or drugs, the offense is considered ‘aggravated’. The charge is Aggravated Vehicular Homicide or Aggravated Vehicular Assault. In both types of charges, the consequences are severe, including a mandatory prison term. If you are in that situation, you may want to read through the Ohio Vehicular Homicide Guide or the Ohio Vehicular Assault Guide to gain a better understanding of the situation. Those books are sold online, and the PDF versions can be downloaded for free from this website, as our lawyers authored and edited the books.

Field Sobriety Testing

As the name implies, field sobriety tests are administered in the ‘field’. Typically, that means the tests are done at or near the crash site. Drivers are not required to take the tests, and there are is no punishment for refusing the tests. Most people do not realize this, so nearly every driver takes the tests when they are requested.

There are three standardized field sobriety tests.

The Horizontal Gaze Nystagmus Test is the test in which the officer has the driver follow a stimulus (a finger or a pen) with their eyes. The officer looks to see if, while following the stimulus horizontally, the eyeballs engage in an involuntary jerking (nystagmus). If the officer observes nystagmus, the officer will consider it evidence the driver is ‘under the influence’ or ‘over the limit’.

The Walk And Turn test requires the driver to walk nine heel-to-toe steps down a line, turn, and walk nine heel-to-toe steps back up the line. During the test, the officer scores the driver’s mistakes on the test (called ‘clues’). According to testing research, if the officer observes two or more clues, the driver is likely ‘under the influence’ or ‘over the limit’.

The One Leg Stand test requires the driver to stand on one leg for thirty seconds while keeping their hands at their sides and watching the raised foot. During the test, the officer scores ‘clues’ for the driver’s mistakes. Two or more clues on this test is considered evidence the driver is probably ‘under the influence’ or ‘over the limit’.

In addition to those three standardized field sobriety tests, officer may administer additional tests which are not standardized. Those include reciting a partial alphabet without singing and counting backward. Whether the tests are standardized or not, effective cross examination of the officers can demonstrate the tests do not measure intoxication. The tests are correlated with an expected alcohol concentration and have not been correlated with drug intoxication.

Drug Recognition Evaluations

Unlike field sobriety tests, drug recognition evaluations are not done in the field. These evaluations are typically conducted at a police station, after a driver is arrested. The evaluations must be done by a certified Drug Recognition Evaluator (also called a Drug Recognition Expert). There are relatively few Drug Recognition Evaluators in Ohio, so they are typically called-in for a case when needed.

Although the drug recognition evaluations are administered by a police officer, they are pseudo-medical exams. The exams include taking the driver’s pulse and vital signs, examining the driver’s eyes, and evaluating the subject’s muscle tone.

The drug recognition evaluations are not as scientific as they seem. Some components of the test are unrelated to drug impairment. Other components of the test are subjective. The evaluation method was not subjected to peer review before it was adopted, and validation studies have shown the evaluations are unreliable.
