DUI / OVI Field Sobriety Tests in Columbus and Delaware, Ohio
Standardized field sobriety tests have been developed by the National Highway Traffic Safety Administration (NHTSA) that assist police officers in determining whether a person should be arrested for DUI / OVI. If police administer these tests during a valid stop, they can be introduced at trial as evidence that the person was driving under the influence of alcohol and/or drugs.
Standardized Field Sobriety Tests for DUI / OVI
There are three standardized field sobriety tests tests:
The Horizontal Gaze Nystagmus Test is used to determine if an involuntary jerking of the eye exists. Studies have demonstrated that the consumption of alcohol can lead to the presence of nystagmus in the eye. The police will have you follow a pen or finger side to side. As your eyes move, the police officer will search to see if your eye has an involuntary jerk. The officer can detect 6 “clues,” of which 4 are needed, to determine if there is a probability that your blood alcohol content (BAC) is 0.08 or higher.
The Walk and Turn Test is administered by having you stand on a line, walk 9 steps, heel-to-toe, down the line, turning around, and repeating. The officer is looking to see if you lose your balance, start too early, take an incorrect number of steps, or fail to touch heel-to-toe. If two or more “clues” are observed, there is a good chance that your BAC is 0.08 or higher.
The One Leg Stand Test has the officer instructing you to raise one leg 6″ of the ground, keeping your arms at your side, and counting to 30. The officer is looking to see if you sway, lose your balance, or put your foot down. If two or more “clues” are observed, there is a probability that your BAC is 0.08 or higher.
In addition to these standardized tests, officers often employ non-standardized tests, such as reciting the alphabet or counting backwards. While there is no correlation between failure on these studies and a high BAC, and there is no standardized procedure, officers make often make judgments based on them.
Having an attorney review the police cruiser video and cross-examining the officer can lead to the discovery of mistakes. Officers can make mistakes in conducting field sobriety tests, and the results of those tests incorrectly administered can be excluded from court proceedings.
