Georgia Field Sobriety Tests

The Law Office of Head & Karettis

There are three approved standardized field sobriety tests in the state of Georgia. Georgia police officers are trained on these NHTSA tests: the HGN (horizontal gaze nystagmus), the one leg stand and the walk and turn. Please read the following information if you have been arrested for a DUI.

- The HGN Test

This test is determined to be the most reliable with a 77% to 88% reliability if the test was administered properly. It is also the only one deemed to be a “scientific” test. A nystagmus is an involuntary jerking of the eyes, which can be brought on by alcohol consumption. However, many people experiences nystagmus naturally in their eyes. The officer will ask you to hold your head still and follow an object (a light, finger or pen) with your eyes only.

The officer is looking for a smooth pursuit. He will be looking for 6 clues, and if he finds 4 clues, you have failed the test.

- The Walk and Turn Test

This test is known as a divided attention test. The officer will be watching your physical performance and balance as well as your ability to follow directions. The officer must demonstrate the test first in order for you to complete it properly.

You will be asked to take 9 heel-to-toe steps forward. You are then to turn and pivot on your front foot and take 9 heel-to-toe steps back counting out loud. The officer will be watching your balance, missing a heel-to-toe step, stepping off the line, an improper turn or failing to count out loud. If you do any of these 2 things, you have failed the test.

- The One Leg Stand Test

This field sobriety test is also a divided attention test. You will be instructed to raise one foot six inches off the ground and count out loud until you are told to stop. At the same time, you must look down, count out loud and keep your toe pointed out.

The officer will be looking to see if you can keep your balance and follow instructions (hence divided attention test). If you put your foot down, lose balance, stop too early, don’t count out loud, use your arms for balance, don’t look down or point your toe out, you will fail. You must meet 2 of these criteria in order to fail the test.
