Field sobriety tests are a method used by law enforcement officers to help determine whether a driver is intoxicated. Unfortunately, however, they aren’t always accurate. Therefore, if you are a Georgia driver, it’s important that you understand what field sobriety tests are and why they can be problematic for sober drivers. Below is an overview of field sobriety tests in Georgia. For additional information on field sobriety tests in Georgia, please contact a Georgia criminal defense attorney.
Common field sobriety tests
There are three standard field sobriety tests: the one-leg stand, the walk-and-turn, and the horizontal gaze nystagmus.
One-leg stand: The one-leg stand requires a driver to raise one leg approximately six inches off the ground. Then, the driver counts in thousands while looking downward and keeping his or her hands at his or her sides until instructed to stop by the police officer. Signs of intoxication while performing this test include swaying, hopping, putting a foot down, and using arms for balance.
Walk-and-turn: This test requires a driver to perform a specific number of heel-to-toe steps on a real or imaginary line, turn around, and perform the same number of heel-to-toe steps in the opposite direction. Signs of intoxication while performing this test include starting the test before instructions have been completed, difficulty balancing, stopping while walking, failing to walk heel to toe, stepping off the line, and taking the wrong number of steps.
Horizontal gaze nystagmus: The horizontal nystagmus test requires a driver to follow an object with his or her eyes. Nystagmus (an involuntary jerking of the eyes) before the eyes reach a 45-degree angle is a sign of intoxication.
Accuracy of field sobriety tests
As noted above, field sobriety tests can be inaccurate. In fact, in a recent study, the one-leg stand was found to be only 65 percent accurate, the walk-and-turn test was found to be only 68 percent accurate, and the horizontal gaze nystagmus test was found to be only 77 percent accurate.
How sober drivers fail field sobriety tests
One reason for the inaccuracy of field sobriety tests is that numerous cognitive and physical conditions can mimic the signs of intoxication. Issues that can lead sober people to fail field sobriety tests include:
- Inner ear problems
- Poor balance
- Speech impediments
- Mental impairments
