Understanding Field Sobriety Tests in Atlanta

Standardized Field Sobriety Tests:

• Walk and Turn Test: This test requires the individual to walk a straight line, heel-to-toe, turn, and walk back in the same manner.
• One-Leg Stand: In this test, the individual is asked to stand on one leg while counting aloud for a specified duration.
• Horizontal Gaze Nystagmus (HGN): This test involves tracking an object with the eyes while the officer observes for involuntary jerking movements.

Accuracy and Limitations:

• Walk and Turn and One-Leg Stand Tests: These tests, while standardized, can be influenced by various factors such as age, physical condition, and environmental conditions. Nervousness or certain medical conditions may also impact performance.
• Horizontal Gaze Nystagmus (HGN): HGN is a physiological phenomenon, but certain medical conditions or medications can cause distinct nystagmus or eye conditions that are not an indication of intoxication.

Non-Standardized Field Sobriety Tests

• Finger-to-Nose Test: The individual closes their eyes, extends their arms, and touches the tip of their nose with each index finger as directed.
• Alphabet Recital or Counting Test: The individual is asked to recite a portion of the alphabet (e.g., "start at E and stop at P") or count backward.
• Romberg Balance Test: The individual stands still with feet together, tilts their head back, closes their eyes, and estimates 30 seconds silently.

Several factors can impact a person's performance on these tests, even if they are sober and under ideal conditions:

• Medical conditions (e.g., vertigo, inner ear problems).
• Physical disabilities or injuries.
• Nervousness or anxiety.
• Weather or road conditions (e.g., uneven pavement, poor lighting).
• Improper instructions or administration by the officer.

Your Rights During a Field Sobriety Test in Atlanta

If you are pulled over on suspicion of driving under the influence (DUI) in Atlanta, you may be asked to perform sobriety test procedures so the police officer can look for signs of intoxication.

These tests are designed to evaluate your coordination, balance, and ability to follow directions.

However, it’s important to understand your rights and how these tests may impact your case.

1. You Have the Right to Refuse the Test

• In Georgia, field sobriety test exercises are voluntary, and you are not legally required to perform them.
• Refusing the test cannot result in the immediate suspension of your driver's license (unlike refusing a chemical test, such as a breathalyzer or blood test).
• However, refusal may still be used as evidence against you in court, as the prosecution may argue that you refused because there were signs of alcohol intoxication.

2. You Are Protected Against Unlawful Stops

• Police must have reasonable suspicion to pull you over and conduct impaired driver tests.
• If you believe you were stopped unlawfully, any evidence collected during the stop (including voluntary field sobriety test results) may be challenged in court.

3. You Can Request Legal Counsel

• Although Georgia law does not grant you the right to consult with an attorney before deciding whether to perform standard field sobriety tests, you can request legal counsel at any time during your interaction with law enforcement.
• Having an attorney early on can help protect your rights and navigate the legal process.

4. You Have the Right to Challenge the Results

If you decide to perform the standardized tests, you can later challenge their validity based on factors such as:

• The officer’s training and experience in administering the tests.
• Environmental conditions (e.g., poor lighting, uneven pavement, inclement weather).
• Your physical or medical condition (e.g., injuries, disabilities, or conditions that affect balance).
• Improper instructions or errors during the administration of the test.

5. You Have the Right to Refuse Self-Incrimination

• Under the Fifth Amendment, you are not required to answer questions or provide information that could incriminate you.
• While you must provide basic information like your name and driver’s license, you do not need to explain where you were coming from, whether you had been drinking, or how much alcohol you consumed.

6. Implied Consent Applies to Chemical Testing, Not Field Sobriety Tests

• Georgia’s implied consent law requires drivers to submit to chemical testing (e.g., blood, breath, or urine tests) after an arrest for suspected DUI. Refusal to comply with chemical testing can lead to license suspension and additional penalties.
• Field sobriety tests are not covered by implied consent, so you can refuse them without immediate administrative consequences.

Challenging Field Sobriety Test Results with a DUI Lawyer in Atlanta

1. Understanding the Limitations of Field Sobriety Tests

Field sobriety tests are designed to measure physical and cognitive impairment, but they are far from foolproof.

Commonly administered FSTs include:

• The Horizontal Gaze Nystagmus (HGN) Test: Measures involuntary eye movements.
• The Walk-and-Turn Test: Evaluates balance, coordination, and the ability to follow instructions.
• The One-Leg Stand Test: Tests balance and focus.

Limitations of FSTs:

• These tests are subjective, meaning results depend on the officer’s interpretation of your level of intoxication.
• External factors such as weather, road conditions, and poor lighting can affect performance.
• Medical conditions, anxiety, and physical injuries can lead to inaccurate results.

A skilled DUI lawyer can identify these weaknesses and argue that the results are unreliable.

2. Challenging Officer Training and Test Administration

Field sobriety tests must be administered according to strict guidelines outlined by the National Highway Traffic Safety Administration (NHTSA).

A DUI attorney can investigate whether:

• The officer conducting the tests was properly trained and certified.
• The tests were administered correctly and in compliance with NHTSA standards.
• The officer provided clear and understandable instructions.

If the officer failed to adhere to proper procedures, the validity of the FST results can be called into question.

3. Examining Environmental Factors

The environment in which field sobriety tests are conducted plays a significant role in their accuracy.

Your attorney will investigate factors such as:

• Road Surface: Uneven or slippery surfaces can affect balance.
• Lighting Conditions: Poor visibility may impact your ability to follow instructions.
• Weather: Rain, wind, or extreme temperatures can make the tests more difficult.
• Footwear: Certain types of footwear, such as high heels or boots, can hinder performance.

By demonstrating that environmental conditions were unfavorable, your lawyer can argue that the test results are not indicative of the level of impairment.

4. Highlighting Medical and Physical Conditions

Medical issues, physical limitations, and even natural nervousness can impact your ability to perform field sobriety tests.

Your attorney may present evidence of:

• Balance or coordination issues caused by conditions like vertigo or past injuries.
• Vision impairments or other health conditions that affect test performance.
• Anxiety or stress, which can make it harder to follow instructions or maintain composure.

This evidence can help create reasonable doubt about the reliability of the test results.

5. Analyzing Police Body Camera Footage

Most law enforcement officers in Atlanta are equipped with body cameras.

These recordings can provide critical evidence about:

• Whether the officer provided clear and correct instructions.
• How the tests were conducted and whether they complied with NHTSA standards.
• Your actual performance on the tests, which may differ from the officer’s written report.

Your DUI lawyer can review this footage to identify discrepancies or procedural errors.

6. Using Expert Testimony

In some cases, your attorney may consult with or call upon an expert witness to challenge the validity of field sobriety tests.

Experts can provide testimony about:

• The inherent inaccuracies of FSTs.
• The impact of specific environmental or medical factors on test performance.
• Alternative explanations for behaviors the officer interpreted as signs of impairment.

7. Arguing for Exclusion of Evidence

If your lawyer can demonstrate that the field sobriety tests were administered improperly or under unfair conditions, they can file a motion to suppress the test results.

If the court grants this motion, the evidence from the field sobriety tests will be excluded, significantly weakening the prosecution's case.
