The Three Standardized Sobriety Tests
Television shows such as “Cops” have documented the implementation of standardized field sobriety tests, so most drivers have at least a passing familiarity with what they might expect in the event of a traffic stop initiated on suspicion of DUI. The three tests that are considered part of the standardized battery are:
- Horizontal Gaze Nystagmus (HGN) – a subject is asked to track a penlight by moving only the eyes, and the officer evaluates the angle at which a subject's eye begins to twitch involuntarily
- Walk-and-Turn (WAT) – a subject is required to walk along a line with 9 steps heel-to-toe, then turn and repeat in the opposite direction while the office observes different behaviors
- One-Leg Stand (OLS) – a subject must stand on one leg with the other raised approximately six inches while counting aloud, and failure to properly execute the task is an indication of possible intoxication
The validity of these sobriety tests does not surpass ninety percent, and that is if it is administered and observed exactly as intended. Contact the Seattle DUI defense lawyers of the Cowan Kirk Law Firm at 866-822-1230 to discuss the facts of your case with an experienced attorney.
