Field Sobriety Tests in Georgia

Your Rights, The Reality, and What Really Happens During a Traffic Stop

You see the blue lights in your rearview mirror, and your heart starts racing. After pulling you over, the officer asks if you’ve been drinking and requests that you step out of your vehicle. Then comes the question that can change everything: “Would you please perform some field sobriety tests for me?” At this moment, knowing your rights and the realities of these tests can make the difference between a simple traffic stop and a life-altering DUI charge.

Field sobriety tests in Georgia are far more complex than most drivers realize. These roadside evaluations serve as a primary tool for law enforcement to gather evidence of impairment, but they’re surrounded by misconceptions, legal nuances, and practical challenges that every Georgia driver should know about.

What Are Field Sobriety Tests and Why Do Police Use Them?

Field sobriety tests are physical and cognitive exercises that law enforcement officers use to evaluate whether a driver may be under the influence of alcohol or drugs. Unlike breathalyzer tests or blood draws, these tests rely on the officer’s observations of your balance, coordination, and ability to follow instructions.

Georgia law enforcement agencies use these tests as investigative tools to build probable cause for a DUI arrest. Under O.C.G.A. § 40-6-391, officers can arrest someone for driving under the influence if they determine the person is “less safe” to drive due to alcohol or drug impairment. Field sobriety tests provide officers with observable behaviors and physical indicators to support this determination.

The results of these tests don’t just influence whether you get arrested – they become evidence presented in court if your case goes to trial. Officers document their observations during the tests, including how you performed each task, your physical appearance, and any statements you made.

Are Field Sobriety Tests Required in Georgia?

Here’s something many Georgia drivers don’t realize: field sobriety tests are completely voluntary. You have the legal right to refuse to perform these tests, and this refusal cannot be used against you in court as evidence of guilt.

This differs significantly from Georgia’s implied consent law, which applies to chemical testing like breathalyzer, blood, or urine tests. Under O.C.G.A. § 40-5-67.1, refusing a chemical test after arrest can result in automatic license suspension and other administrative penalties. However, field sobriety tests fall outside this law.

Why Officers Don’t Always Make This Clear

Police officers are not required to inform you that field sobriety tests are voluntary. In fact, the way they phrase their requests often makes these tests sound mandatory. Officers might say things like:

• “I need you to perform some tests for me”
• “Please step out and do these tests”
• “Standard procedure requires these tests”

This phrasing can make drivers feel they have no choice but to comply. However, you always have the right to politely decline by saying something like, “Officer, I prefer to exercise my right to refuse field sobriety tests.”

The Three Standardized Field Sobriety Tests Used in Georgia

The National Highway Traffic Safety Administration (NHTSA) has established three standardized field sobriety tests that law enforcement agencies across Georgia use. These tests have specific procedures and criteria that officers are supposed to follow.

Horizontal Gaze Nystagmus (HGN) Test

The HGN test involves the officer observing your eyes as you track a moving object, typically a pen or small flashlight, horizontally across your field of vision. The officer looks for involuntary jerking movements of your eyes, called nystagmus, which can be more pronounced when someone has consumed alcohol.

During this test, the officer will:

• Hold an object 12-15 inches from your face
• Move it slowly from side to side
• Look for specific clues in each eye
• Check for smooth pursuit, distinct nystagmus at maximum deviation, and onset of nystagmus before 45 degrees

The officer scores this test based on six possible clues (three for each eye). According to NHTSA training, if four or more clues are observed, it suggests a blood alcohol concentration of 0.08% or higher.

Walk-and-Turn Test

This divided attention test requires you to walk heel-to-toe along a straight line, turn around using a specific technique, and walk back while counting each step aloud. The officer observes your ability to maintain balance while following multiple instructions simultaneously.

Specific clues the officer looks for include:

• Cannot keep balance during instructions
• Starts before instructions are finished
• Stops while walking
• Does not touch heel-to-toe
• Steps off the line
• Uses arms to balance
• Makes an improper turn
• Takes an incorrect number of steps

According to NHTSA standards, if you exhibit two or more clues during this test, it indicates a blood alcohol concentration of 0.08% or above.

One-Leg Stand Test

This test requires you to stand on one foot with the other foot approximately six inches off the ground while counting aloud in a specific manner (one thousand-one, one thousand-two, etc.) for 30 seconds. The officer observes your balance and ability to follow instructions.

The officer looks for four specific clues:

• Swaying while balancing
• Using arms to balance
• Hopping to maintain balance
• Putting your foot down

If you exhibit two or more of these clues, NHTSA training suggests this indicates impairment consistent with a blood alcohol concentration of 0.08% or higher.

Non-Standardized Tests

Some officers may also request non-standardized tests such as:

• Finger-to-nose test
• Alphabet recitation
• Counting backwards
• Finger counting

These tests lack the scientific validation of the standardized tests and are generally considered less reliable in court. However, officers may still use your performance on these tests as evidence of impairment.

How Are Field Sobriety Tests Actually Scored?

The scoring of field sobriety tests is more subjective than many people realize. While NHTSA provides specific criteria for each test, the officer makes judgment calls about what constitutes a “clue” of impairment. This subjectivity creates opportunities for both false positives and valid legal challenges.

Factors That Can Affect Test Performance

Many legitimate factors can affect your performance on field sobriety tests that have nothing to do with alcohol or drug impairment:

Physical conditions:

• Inner ear problems or balance disorders
• Leg, back, or foot injuries
• Natural coordination issues
• Fatigue
• Medical conditions affecting balance or coordination

Environmental factors:

• Uneven or slippery road surfaces
• Poor lighting conditions
• Extreme weather (cold, heat, rain, wind)
• Traffic noise and distractions
• Stress from the traffic stop itself

Clothing and footwear:

• High heels or uncomfortable shoes
• Tight or restrictive clothing
• Heavy coats or boots that affect movement

Age and physical fitness:

• Natural decline in balance and coordination with age
• Being overweight or out of shape
• Pregnancy

Officer Training and Administration

The reliability of field sobriety tests depends heavily on proper administration by the officer. Officers must follow specific protocols for each test, including:

• Providing clear, standardized instructions
• Demonstrating tests correctly
• Ensuring appropriate testing conditions
• Observing for the specific, standardized clues
• Accurately documenting observations

When officers deviate from these protocols or fail to consider alternative explanations for poor performance, the reliability of test results becomes questionable.

Can You Refuse Field Sobriety Tests? What Happens If You Do?

Yes, you can refuse field sobriety tests in Georgia, and this refusal cannot be used as evidence against you in a DUI prosecution. However, refusing these tests does not prevent an officer from arresting you if they believe they have sufficient probable cause based on other observations.

Consequences of Refusing

While refusing field sobriety tests won’t result in automatic license suspension like refusing a chemical test, it may influence the officer’s decision-making process. Without test results, the officer must base their probable cause determination on:

• Your driving behavior before the stop
• Your appearance and demeanor
• The odor of alcohol
• Your speech patterns
• Any admissions you make
• Other observable signs of impairment

Practical Considerations

The decision whether to submit to or refuse field sobriety tests involves weighing several factors:

Reasons you might consider refusing:

• You have physical limitations that could affect performance
• Environmental conditions are poor
• You’re wearing inappropriate footwear
• You’re naturally uncoordinated
• You want to avoid providing additional evidence against yourself

Reasons you might consider participating:

• You believe you’ll perform well and it might help your case
• You want to appear cooperative
• You think refusal will make you look guilty

Remember that field sobriety tests are designed to help officers build a case against you, not to prove your innocence. Even sober individuals can fail these tests under certain circumstances.

How Field Sobriety Test Results Are Used in Court

Field sobriety test results serve as evidence in DUI prosecutions, but they’re not automatically accepted without scrutiny. Both prosecutors and defense attorneys examine these results carefully.

Prosecution’s Use of Test Results

Prosecutors typically use field sobriety test results to:

• Establish probable cause for the arrest
• Demonstrate observable signs of impairment
• Corroborate other evidence of intoxication
• Counter defense arguments about sobriety

The prosecution will present the officer’s testimony about your performance, often supplemented by video footage if available.

Defense Challenges to Test Results

A skilled DUI defense attorney can challenge field sobriety test results in several ways:

Challenging administration:

• Improper instructions given by the officer
• Failure to follow standardized procedures
• Inadequate demonstration of tests
• Testing under inappropriate conditions

Challenging interpretation:

• Officer’s subjective scoring of performance
• Failure to consider alternative explanations
• Misidentification of standardized clues
• Over-reliance on non-standardized tests

Challenging reliability:

• Medical conditions affecting performance
• Environmental factors impacting results
• Inappropriate footwear or clothing
• Officer training deficiencies

The Role of Video Evidence

Many police vehicles and officers now have recording equipment that captures field sobriety tests. This video evidence can be helpful or harmful depending on your actual performance and the circumstances.

Video evidence can help your defense if it shows:

• Poor testing conditions
• Officer procedural errors
• Your actual performance was better than described
• Environmental factors affecting the tests

However, video can also provide clear evidence of poor performance that supports the prosecution’s case.

What Should You Do During a DUI Stop in Georgia?

Knowing how to handle yourself during a DUI stop can significantly impact the outcome of your case. Here are practical steps to protect yourself while remaining respectful and compliant with lawful orders.

Initial Contact with the Officer

When an officer approaches your vehicle:

• Keep your hands visible on the steering wheel
• Wait for the officer to ask for documents before reaching for them
• Be polite but avoid admitting to drinking or drug use
• Don’t volunteer information beyond what’s requested

If Asked to Exit Your Vehicle

Officers often ask drivers to step out during DUI investigations. You must comply with this request, as it’s considered a lawful order for officer safety.

Once outside your vehicle:

• Stand where the officer directs you
• Keep your hands visible
• Maintain a respectful demeanor
• Listen carefully to what the officer says

Responding to Questions About Drinking

Officers typically ask questions like:

• “Have you been drinking tonight?”
• “How many drinks have you had?”
• “When was your last drink?”

You have the right to remain silent and not answer these questions. You can politely respond: “Officer, I’m exercising my right to remain silent.”

When Field Sobriety Tests Are Requested

If an officer requests field sobriety tests, remember:

• These tests are voluntary in Georgia
• You can politely decline without legal penalty
• Your refusal cannot be used as evidence of guilt
• Consider your physical condition and circumstances

You might respond: “Officer, I prefer to exercise my right to decline field sobriety tests.”

After Arrest

If you’re arrested for DUI:

• Don’t resist or argue with officers
• Don’t make statements about the case
• Ask to speak with an attorney
• Be aware of your rights regarding chemical testing

Key Takeaways

• Field sobriety tests are voluntary in Georgia – You have the legal right to refuse these tests without penalty, and your refusal cannot be used as evidence against you in court.
• These tests are subjective – Officer interpretation plays a significant role in scoring, and many factors unrelated to impairment can affect performance.
• Physical and medical conditions matter – Balance disorders, injuries, age, footwear, and environmental conditions can all impact test results regardless of sobriety.
• Implied consent applies only to chemical tests – While you can refuse field sobriety tests, refusing breath, blood, or urine tests after arrest carries automatic penalties.
• Your behavior during the stop matters – Remaining respectful while exercising your rights, avoiding unnecessary statements, and following lawful orders can help your case.
• Video evidence can be crucial – Police recordings of field sobriety tests can either help or hurt your defense depending on what they show.

Frequently Asked Questions

Can I refuse field sobriety tests if I haven’t been drinking? Yes, you can refuse field sobriety tests whether you’ve been drinking or not. These tests are voluntary regardless of your sobriety level, and many sober people fail them due to physical limitations, nervousness, or poor testing conditions.

Will refusing field sobriety tests make me look guilty? Legally, your refusal cannot be used as evidence of guilt. However, some people worry about appearing uncooperative. Remember that these tests are designed to gather evidence against you, not to prove your innocence.

What if I have a medical condition that affects my balance? If you have any medical condition that could affect your performance on field sobriety tests, this is valuable information for your defense. Consider declining the tests and documenting your condition with medical records and professional testimony.

Can police arrest me for DUI without field sobriety tests? Yes, officers can arrest you for DUI based on other evidence such as your driving behavior, appearance, odor of alcohol, slurred speech, and other observable signs of impairment. Field sobriety tests are just one tool officers use to build probable cause.

How accurate are field sobriety tests? According to NHTSA studies, when properly administered under ideal conditions, the standardized field sobriety tests have varying accuracy rates. However, real-world conditions rarely match laboratory settings, and many factors can affect test reliability.

Should I take field sobriety tests if I’ve only had one drink? Even small amounts of alcohol, combined with nervousness, physical limitations, or poor testing conditions, can affect test performance. Consider your individual circumstances, including any medical conditions, current physical state, and environmental factors.

What happens if I fail field sobriety tests but pass a breathalyzer? This scenario can actually help your defense. If you performed poorly on field sobriety tests but had a low or legal blood alcohol concentration, it suggests factors other than alcohol impairment affected your test performance.

Can field sobriety test results be thrown out of court? Yes, if your attorney can demonstrate that the tests were improperly administered, that alternative explanations exist for poor performance, or that the officer lacked proper training, the court may exclude test results from evidence.
