The Accuracy of Field Sobriety Tests
Why You Need a DUI Attorney in Atlanta
For decades, it has been apparent that many field sobriety tests are unscientific
and inaccurate, with some studies suggesting a nearly 30% to 50% error
rate. Particularly for drivers who may have a borderline BAC, these field
sobriety tests can be highly unreliable.
Sober people are known to "fail" these tests simply because of
misunderstood instructions, anxiety, language barriers, or simple distractedness.
Sometimes, an officer may not have the proper training to administer these
tests correctly. The results of field sobriety evaluations are far from
Talk to an Atlanta drunk driving lawyer at Willis Law Firm to learn how you could counter this evidence
and go on to win your case.
Despite the dubious results these evaluations can provide, police officers
often rely on some or all of the following tests to assess whether or
not someone has been driving impaired:
Horizontal Gaze Nystagmus (HGN) Test: This eye test involves an officer holding out an object such as a penlight
and asking you to follow it with your eyes. If your eyes twitch before
hitting a 45-degree angle, or if your eyes jerk in various ways, you could
be suspected of DUI. This test is considered scientific and highly reliable-in
ideal conditions. Impairment is not the only reason this test can be failed
of course, as prescription medication or medical issues could produce
similar results, or an officer can administer the test incorrectly.
One-Leg-Stand Test: This involves standing on one leg and counting, often for about 30 seconds.
Waving your arms, hopping, and letting your foot touch the ground are
a few of the simple ways this test can be failed. Of course, there are
a host of other reasons besides impairment that could be the real reason
behind a failed test, such as being overweight, taking medication, wearing
bad shoes, or getting distracted.
Walk-and-Turn Test: This is the test in which participants are supposed to take nine heel-to-toe
steps, twist around, and then take those same steps back, all while maintaining
balance, keeping to a straight line, and counting aloud. Age, weight,
and nervousness are just a few of the reasons a failed test could be inaccurate.
