The Different Tests | Are They Accurate?
It’s common practice for law enforcement officers in Maryland to request that a motorist take a “field sobriety test” if there’s suspicion of driving under the influence (DUI) or driving while impaired (DWI). Those tests can take a number of different forms:
- The horizontal gaze nystagmus—With this test, the officer holds an object in front of your eyes and moves it back and forth, looking for a “jerking” movement in your eyes, which is considered an indication of alcohol intoxication.
- The one-leg stand—This assessment involves standing on one foot for up to 30 seconds. Officers look for problems with balance, as well as difficulty counting.
- The walk-and-turn test—This is the “heel-to-toe” test, where you must put one foot in front of the other, walk in a specific direction, and then change directions.
The Reliability of Field Sobriety Tests
In testing conducted by the Southern California Research Institute in the 1970s, the accuracy of field sobriety tests was mixed. The report found that almost one of every four horizontal gaze nystagmus tests was inaccurate and that the other two tests were accurate about 2/3 of the time.
