When you are pulled over, the last thing you want to hear is a driver ask if you’ve been drinking. Because the officer likely suspects that you are under the influence, they may ask you to take a field sobriety test. It’s important to familiarize yourself with these tests and what your rights are. The following blog explores whether or not field sobriety tests are mandatory and what to do if an officer wants your participation. Keep reading to learn more about this process and how a Cobb County DUI lawyer can help you if you’ve been pulled over on suspicion of drunk driving.

What Are Field Sobriety Tests?

Field sobriety tests are a set of physical assessments administered by a police officer to determine whether or not a driver is under the influence of drugs or alcohol. These tests are designed to provide law enforcement with additional evidence against a driver they believe is intoxicated.

The test typically entails three main sections. The first is the Horizontal Gaze Nystagmus, which the officer will use to look for involuntary eye movement that indicates intoxication. Next is the infamous “walk and turn” test, which requires a series of steps. The officer will examine your ability to follow directions and whether or not you can balance. Finally, you may be asked to stand on one leg and balance, again, with the officer assessing you for signs of impairment.

Standardized vs. Non-Standardized Evaluations Under NHTSA Guidelines

The National Highway Traffic Safety Administration (NHTSA) establishes strict, standardized administration and scoring guidelines for roadside evaluations in Georgia.

  • Horizontal Gaze Nystagmus (HGN): This test examines the eyes for involuntary jerking as they track a moving stimulus
  • Walk-and-Turn (WAT): This is a physical assessment that allows the officer to examine balance and command execution through a series of nine heel-to-toe steps
  • One-Leg Stand (OLS): This test evaluates both physical balance and mental concentration while holding one foot six inches off the ground for 30 seconds.
  • Non-Standardized Tests: Other tests that have not been validated by the NHTSA include reciting the alphabet, counting backwards, or touching your nose

These tests are unfortunately flawed, as they rely heavily on the officer’s subjective opinion to determine whether or not someone appears to be under the influence. Additionally, if the officer administers the test incorrectly, it can skew the results.

What Should I Do if I’m Asked to Take One?

When talking with the officer conducting the traffic stop, they will likely make it seem as though your participation in the field sobriety test is mandatory. However, it’s critical to understand that you do not need to take this test. Under Georgia’s implied consent laws (codified under O.C.G.A. § 40-5-67.1), drivers who refuse to take breathalyzers or chemical testing requested after a lawful arrest are automatically subject to a license suspension. However, field sobriety tests are not covered under these laws, meaning you are well within your right to refuse.

Understanding Roadside Rights and Pre-Arrest Refusal Rules

It is important to understand that there is a distinction between field sobriety tests and chemical tests. Typically, any pre-arrest evaluations are voluntary, but after you are arrested, you are required to submit to mandatory chemical testing.

If you are pulled over and the officer asks you to exit your vehicle, you legally must comply. However, you have no obligation to participate in a field sobriety test in Georgia. As such, you can politely inform the officer that you do not want to participate and inform them that you would like to invoke your right to remain silent.

Why Drivers Choose to Decline Voluntary Field Tests

Roadside physical tests are designed to gather evidence establishing probable cause for a DUI arrest under O.C.G.A. § 40-6-391.

  • Environmental factors like uneven pavement, dark roads, or flashing police lights compromise test accuracy.
  • Medical conditions, joint injuries, inner ear issues, or fatigue frequently mimic signs of alcohol impairment.
  • Extreme nervousness during a traffic stop can lead to physical tremors or missed instructions.
  • Performance scores are recorded purely through the subjective interpretation of the arresting officer.

In the event that you are arrested during the traffic stop, the police now have less evidence to use against you. Being subjected to testing is a nerve-wracking situation, so you may stumble or make an error because of nerves. However, the officer can use this as evidence of intoxication. As such, refusing to take the test and limiting the evidence against you is critical.
