Harford County DUI – Field Sobriety Testing

Navigating the complex landscape of legal procedures during a DUI stop can be daunting. One of the most critical and often misunderstood aspects is the field sobriety test (FST). This blog post aims to demystify the legalities surrounding FSTs, providing a comprehensive guide for drivers. We will explore the types of FSTs, their scientific validity, your rights when asked to perform them, the legal implications of refusal, and what to do if you find yourself in this situation.

Understanding Field Sobriety Tests: More Than Just Walking a Line

Field sobriety tests are a battery of tests designed to assess a driver’s physical and mental impairment. Law enforcement officers use these tests to gather probable cause for a DUI arrest. It’s crucial to understand that FSTs are not definitive proof of intoxication but rather indicators that an officer uses in conjunction with other observations (such as odor of alcohol, slurred speech, or bloodshot eyes) to establish reasonable suspicion.

There are three standardized field sobriety tests (SFSTs) recognized by the National Highway Traffic Safety Administration (NHTSA):

• Horizontal Gaze Nystagmus (HGN): This test observes the involuntary jerking of the eyes that occurs when a person is impaired. The officer will ask you to follow a small object (like a pen or their finger) with your eyes, without moving your head, while they observe your eye movements for distinct “clues” of impairment. These clues include a lack of smooth pursuit, distinct nystagmus at maximum deviation, and the onset of nystagmus prior to 45 degrees. The HGN test is often considered the most reliable of the SFSTs, as nystagmus is an involuntary reaction, less susceptible to a subject’s intentional control. However, various medical conditions, medications, and even fatigue can cause nystagmus, making it not solely indicative of alcohol impairment.
• Walk-and-Turn (WAT): This test assesses a person’s balance, coordination, and ability to follow instructions. The officer will instruct you to take nine heel-to-toe steps along a straight line, turn around in a specific manner, and return nine heel-to-toe steps. During this test, the officer looks for several clues: inability to balance during instructions, starting too soon, stopping while walking, not touching heel-to-toe, stepping off the line, using arms for balance, making an improper turn, or taking an incorrect number of steps. This test requires both physical dexterity and the ability to retain and execute multi-step instructions, making it challenging for even unimpaired individuals under stressful conditions or on uneven surfaces.
• One-Leg Stand (OLS): Similar to the Walk-and-Turn, the One-Leg Stand test evaluates balance and coordination. You will be asked to stand with one foot approximately six inches off the ground, held parallel to the ground, for thirty seconds, while counting aloud. Officers observe for four clues: swaying, using arms for balance, hopping, or putting the foot down. Like the WAT, this test can be affected by physical limitations, footwear, and the testing environment.

Beyond these standardized tests, officers may ask you to perform non-standardized tests, such as reciting the alphabet backward, counting backward, or touching your nose with your finger. While these may seem like simple requests, their scientific validity as indicators of impairment is often questioned in court.

The Science (and Lack Thereof) Behind FSTs

While NHTSA promotes the SFSTs as scientifically validated, it’s crucial to understand the nuances of this “validation.” The original research that led to the development of the SFSTs was conducted in the late 1970s and early 1980s. While these studies did show a correlation between certain performance deficits on the tests and blood alcohol content (BAC), the accuracy rates often cited (e.g., HGN 88% accurate in detecting a BAC of 0.08% or greater) are for controlled laboratory settings with trained evaluators.

In real-world scenarios, various factors can significantly impact the reliability of FST results:

• Officer Training and Adherence to Protocol: Proper administration of SFSTs is critical. Any deviation from the standardized instructions, such as incorrect demonstration or timing, can compromise the test’s validity. An officer’s subjective interpretation of “clues” can also introduce bias.
• Environmental Conditions: The location where the tests are administered plays a significant role. Uneven pavement, gravel, sloped surfaces, poor lighting, wind, or rain can make it difficult for even a sober person to perform well on balance and coordination tests.
• Physical Limitations of the Driver: Age, weight, injuries, chronic medical conditions (e.g., inner ear problems, vertigo, neurological disorders, diabetes), and even certain prescription medications can affect a person’s ability to perform FSTs, regardless of alcohol consumption. Footwear (e.g., high heels, uncomfortable shoes) can also impact performance.
• Nervousness and Stress: Being pulled over by law enforcement is inherently stressful. This stress can lead to trembling, fumbling, or difficulty following instructions, which an officer might misinterpret as signs of impairment.
• Officer Bias: While not always intentional, an officer’s pre-conceived notion that a driver is impaired (perhaps due to the smell of alcohol or observed driving behavior) can influence their interpretation of FST performance.

Understanding these limitations is vital, as they can form the basis of a strong defense in a DUI case.

Your Rights: To Perform or Not to Perform?

This is where the legalities become paramount. When an officer asks you to perform field sobriety tests, you are often under the impression that you must comply. However, this is generally not true. In most jurisdictions in the United States (including Maryland), you have the right to refuse to participate in field sobriety tests.

Unlike  a chemical test (blood, breath, or urine test) after an arrest, FSTs are considered voluntary. Refusing a chemical test after arrest typically carries administrative penalties, such as an automatic license suspension, due to implied consent laws. However, there’s generally no direct legal penalty for refusing FSTs before an arrest.

Why might you refuse?

• No Downside (Generally): As mentioned, there are typically no direct legal penalties for refusing FSTs.
• Avoiding Self-Incrimination: By performing FSTs, you are essentially providing the officer with evidence that can be used against you to establish probable cause for an arrest. Even if you believe you are sober, your performance could be negatively impacted by factors beyond your control (stress, uneven ground, physical limitations), leading to an arrest.
• Lack of Reliability: Given the inherent limitations and subjective nature of FSTs, your performance might not accurately reflect your level of impairment.

It’s important to state your refusal clearly and politely. Something like, “Officer, I respectfully decline to perform any field sobriety tests.” Avoid arguing or being confrontational.

What Happens If You Refuse FSTs?

While there’s generally no direct legal penalty for refusing FSTs, it’s crucial to understand the potential indirect consequences:

• Increased Likelihood of Arrest: If an officer has other observations that lead them to believe you are impaired (e.g., odor of alcohol, slurred speech, admission of drinking, erratic driving), refusing FSTs might lead them to arrest you based on those observations alone. Without the FSTs, the officer might argue they had no other way to assess your sobriety at the scene. However, an arrest without FSTs can sometimes make it harder for the prosecution to prove impairment in court, as they have less “evidence” from the roadside.
• No Evidence for Your Defense: While refusing FSTs limits the evidence against you, it also means there’s no evidence for you. If you perform well on FSTs, that positive performance could potentially be used to argue against impairment. However, given the subjective nature of the tests, the risk of a “poor” performance outweighing a “good” one is often significant.

The decision to refuse FSTs is a strategic one, and it’s best to be informed before you are ever in that situation. Many legal experts advise refusing FSTs due to their inherent unreliability and the potential for creating evidence against oneself.

Implied Consent and Post-Arrest Testing

It’s vital to distinguish between pre-arrest FSTs and post-arrest chemical tests. Every state in the U.S. has “implied consent” laws. This means that by obtaining a driver’s license, you implicitly consent to chemical testing (breath, blood, or urine) if you are lawfully arrested for DUI.

If you refuse a chemical test after being lawfully arrested for DUI, you face immediate and severe administrative penalties, typically including:

• Automatic License Suspension: This is often a significant suspension, regardless of whether you are ultimately convicted of DUI. The length of the suspension varies by state and whether it’s a first offense.
• Enhanced Penalties in Court: While not directly a criminal charge for refusing, your refusal can often be used as evidence against you in a DUI prosecution, implying consciousness of guilt. Some states also impose harsher criminal penalties for DUI convictions when there was a refusal to submit to a chemical test.

There are limited circumstances where refusal of a chemical test may be legally justified (e.g., if the officer did not have probable cause for the arrest, or if there were issues with the administration of the test), but these are complex legal arguments best handled by an experienced attorney.

What to Do If You’re Pulled Over for Suspected Harford County DUI

1. Pull Over Safely: Activate your turn signal and pull over to the right shoulder as soon as it’s safe to do so.
2. Remain Calm: Take a deep breath. Being nervous is normal, but try to remain composed.
3. Keep Hands Visible: Place both hands on the steering wheel, visible to the officer.
4. Be Polite and Cooperative (within your rights): Address the officer respectfully.
5. Provide Requested Documents: Have your driver’s license, registration, and proof of insurance readily available.  You are required to provide this information.
6. Answer Limited Questions: You are generally required to provide your name, address, and identify yourself. You are not required to answer questions about where you’re coming from, where you’re going, or how much you’ve had to drink. These questions are designed to elicit incriminating statements. You can politely state, “Officer, I prefer not to answer any questions without an attorney present.”
7. Refuse FSTs (Politely): If asked to perform FSTs, politely state, “Officer, I respectfully decline to perform any field sobriety tests.”
8. Understand Implied Consent: If you are arrested, the officer will likely request a chemical test. At this point, implied consent laws come into play. While you can refuse, be aware of the immediate administrative consequences (license suspension).
9. Do Not Resist Arrest: If the officer decides to arrest you, do not physically resist, even if you believe the arrest is unlawful. Resisting arrest can lead to additional criminal charges.
10. Contact an Attorney Immediately: The moment you are released or have the opportunity, contact an attorney specializing in DUI defense. Do not discuss your case with anyone until you have consulted with your lawyer.

The Role of a Harford County DUI Defense Attorney

If you have been arrested for DUI, particularly if FSTs were administered, retaining an experienced DUI defense attorney is paramount. An attorney can:

• Challenge Probable Cause: They will scrutinize the officer’s initial observations and the administration of FSTs to determine if there was sufficient probable cause for your arrest. If not, the case could be dismissed or evidence suppressed.
• Analyze FST Results: Your attorney will review dashcam or bodycam footage of the FSTs to identify any deviations from standardized protocol, environmental factors, or your physical limitations that could have skewed the results. They can bring in expert witnesses to testify about the unreliability of FSTs under specific conditions.
• Negotiate with the Prosecution: An attorney can negotiate for reduced charges or alternative sentencing.
• Represent You in Court: They will aggressively defend your rights and build the strongest possible case on your behalf, whether through motions to suppress evidence, cross-examination of officers, or presenting expert testimony.
• Explain Your Rights and Options: They will guide you through the complex legal process, explaining your rights, the potential penalties, and the best course of action for your specific situation.

Conclusion

Field sobriety tests are a critical component of DUI investigations, but they are far from infallible. Understanding their limitations, your rights regarding refusal, and the implications of implied consent laws is essential for any driver. While the decision to perform or refuse FSTs is a personal one, most legal experts advise polite refusal due to their subjective nature and potential to create evidence against you. The best defense against a DUI charge begins with knowing your rights and exercising them wisely. Should you ever find yourself in this stressful situation, remember to remain calm, assert your rights, and contact a qualified DUI defense attorney as soon as possible. Your future and your driving privileges may depend on it.
