DUI breathalyzer Test in AtlantaThe National Highway Traffic Safety Administration implemented a Standardized Field Sobriety Test battery (SFST) in 1981 after six years of research. The SFST battery helps police officers determine whether a person’s blood alcohol content might be over .10. However, since the implementation of the SFST battery, several states, including Georgia, lowered the legal blood alcohol concentration from 0.10 to 0.08 for most drivers. Commercial drivers in Georgia cannot have a blood alcohol concentration of more than 0.04. If you have had to take the SFST test contact an experienced DUI defense attorney to discuss your legal options.

The Standardized Field Sobriety Test Battery

The SFST battery includes three “tests” that police officers give to a driver whom they suspect of driving under the influence. Officers administer these tests before they arrest the suspect or ask them to submit to chemical tests. The officers who administer the tests are trained to do so. If a patrol officer stops you and suspects you of a DUI but has not been trained in administering the tests, they will call another officer who has been trained.


The Horizontal Gaze Nystagmus Test

When your eyes move to the side, they involuntarily jerk. Alcohol in your system causes this jerking to become more noticeable. The more impaired you are, the more exaggerated the jerking becomes in most people. An officer will have you follow their finger or a pen with your eyes and watch your eyes for excessive jerking.

Walking and Turning

When an officer has you walk and turn, they are checking to see that you can follow instructions. If you are impaired, it is more difficult for you to follow instructions.

Standing on One Leg

This is a test that can be difficult for some people even if they are not impaired. This test checks your balance, which gets worse the more impaired you are.

Problems With the SFST Battery of Tests

The major problem with the SFST battery is that the tests are not 100 percent accurate. When the legal blood alcohol limit was dropped from 0.10 to 0.08, seven police officers collected data during their regular patrols to determine the SFST’s accuracy.

Their findings showed that of 298 tests they conducted during the study period, the horizontal gaze nystagmus test only accurately identified 90 percent of the subjects the officers suspected were under the influence based on the horizontal gaze nystagmus test. While 90 percent might seem like a high percentage, for the 10 percent of individuals who were not under the influence but were still asked to take a chemical test, a 90 percent accuracy rate is too low. The other tests in the SFST battery were not evaluated for accuracy in identifying blood alcohol levels at or below 0.08.

Additional Accuracy Issues

In many cases, people may not be able to complete one or more of the tests in the SFST battery. A person may have eye problems that cause excessive skipping as their eyes move from side to side, even when they are not impaired. This kind of condition can result in a false positive in the horizontal gaze nystagmus test. Other people may have health issues that prevent them from balancing on one foot or from walking in a straight line.

If you have a medical issue, you should let the officer know that it will affect your performance on the SFST battery. You can also refuse to take the SFST battery.

Submitting to the Battery of Tests

Because the SFST battery does not measure blood alcohol content but rather simply gives an officer probable cause to arrest you, you do not have to agree to take the tests. However, if you refuse testing, you will probably be asked to take a chemical test. While you do not have to take the SFST battery, your license will be suspended for a year for refusing to take a chemical test, which may be a Breathalyzer, blood, or urine test.
