Being subjected to field sobriety tests (FSTs) during a DUI stop can be a daunting experience. These tests are designed to assess impairment and provide evidence in support of a DUI charge. However, the accuracy and administration of these tests can be challenged in court. This detailed guide discusses the strategies for challenging FSTs in Florida DUI cases, outlining relevant statutes, common defenses, and why legal representation is critical.

Field sobriety tests in Florida are governed by both state laws and judicial decisions which outline the legal framework for DUI enforcement and the admissibility of FSTs in court.

Florida Statutes § 316.193

Florida Statutes § 316.193 defines driving under the influence and the penalties involved. It specifies that a person is guilty of DUI if they are driving or in actual physical control of a vehicle within the state while under the influence of alcoholic beverages, chemical substances, or controlled substances when affected to the extent that their normal faculties are impaired.

Standardized Field Sobriety Tests Endorsed by NHTSA

The National Highway Traffic Safety Administration (NHTSA) endorses three standardized field sobriety tests: the Horizontal Gaze Nystagmus (HGN), the Walk-and-Turn, and the One-Leg Stand tests. Florida law enforcement agencies use these tests as part of their DUI investigations.

Legal Definitions

Understanding the legal definitions related to FSTs is crucial for identifying potential areas of challenge:

Field Sobriety Tests (FSTs)

FSTs are a battery of tests used by law enforcement to determine impairment due to alcohol or drugs. These tests can include physical or cognitive tasks that assess balance, coordination, and the ability to perform divided attention tasks.

Horizontal Gaze Nystagmus (HGN)

The HGN test involves observing the eyes of a suspect as they follow a moving object such as a pen or flashlight. The officer looks for involuntary jerking of the eyes, which can be an indicator of intoxication.

Walk-and-Turn & One-Leg Stand

These tests assess a suspect's ability to perform tasks requiring physical balance, coordination, and the ability to follow instructions, which are faculties often impaired by alcohol or drugs.

Strategies for Challenging FSTs

Challenging the results and the administration of field sobriety tests is a complex but often effective aspect of DUI defense. The following strategies are commonly employed:

1. Questioning Test Conditions

The conditions under which FSTs are administered can significantly affect performance. Defense strategies may involve highlighting adverse conditions such as uneven surfaces, poor lighting, inclement weather, or traffic distractions that could undermine the reliability of the test results.

2. Highlighting Officer Training and Protocol Adherence

The effectiveness of FSTs depends heavily on the proper training of the administering officer and strict adherence to standardized procedures. Any deviation from NHTSA guidelines or lack of proper training can be grounds for challenging the test results. Defense counsel can request training records and certifications to scrutinize the officer’s qualifications and adherence to standard protocols.

3. Pointing Out Physical or Medical Conditions

Defendants may have physical or medical conditions that affect their ability to perform FSTs—conditions such as injuries, chronic pain, or disabilities, and even factors like age or weight. Medications can also affect test performance. Presenting medical records or expert testimony may help discredit FST results.

4. Challenging the Subjectivity of Observations

FSTs rely heavily on the subjective observations of the arresting officer. Defense strategies might include questioning the officer’s interpretations of the results, pointing out the inherent subjectivity of what constitutes signs of impairment, and contrasting these observations with other objective evidence such as video footage from dashcams or bodycams.

5. Use of Expert Witnesses

Expert witnesses in fields such as toxicology, ophthalmology, or kinesiology can provide testimony that challenges the validity of FST results. They can offer insights into the scientific shortcomings of FSTs and how certain conditions can affect the reliability of the results.

Challenging Field Sobriety Tests in Florida DUI Cases FAQs

What are field sobriety tests (FSTs) and why are they used?
Field sobriety tests are a series of physical and cognitive exercises administered by police officers during a traffic stop where impairment due to alcohol or drugs is suspected. These tests assess coordination, balance, and the ability to perform tasks requiring divided attention. They aim to provide evidence of impairment which can support a DUI arrest.

Can I refuse to take field sobriety tests in Florida?
Yes, in Florida, you are legally allowed to refuse to perform field sobriety tests. Unlike chemical tests, where refusal can result in immediate administrative penalties like license suspension, there are no direct legal penalties for refusing FSTs. However, refusing these tests does not guarantee that you won’t be arrested for DUI, and this refusal can still be mentioned in court as evidence of consciousness of guilt.

How accurate are field sobriety tests?
The accuracy of field sobriety tests can vary significantly and is influenced by a variety of factors, including the individual’s physical condition, nervousness, and the environment in which the tests are conducted. The National Highway Traffic Safety Administration (NHTSA) claims that when administered correctly, these tests are reliable indicators of impairment. However, the subjective nature of assessing test performance can lead to inaccuracies.

What happens if I fail field sobriety tests?
Failing field sobriety tests can lead to your arrest for DUI. The officer will use the results as part of their overall assessment of your impairment, which also includes observations of your behavior, appearance, and any evidence of alcohol or drug use. Failed FSTs will likely be used as evidence in court to support the prosecution’s case for DUI.

How can an attorney help if I've failed field sobriety tests?
An experienced DUI attorney can challenge the validity of the field sobriety tests by questioning the conditions under which they were performed, the training and objectivity of the officer, and your physical or medical conditions that could affect your performance. Attorneys can also consult expert witnesses to discredit the tests’ accuracy or relevance to your specific situation.

Are there specific conditions under which field sobriety tests should not be administered?
Yes, field sobriety tests should not be administered in certain conditions that could compromise the accuracy of the results. This includes inclement weather, uneven or poorly lit surfaces, and environments with excessive distractions. Additionally, individuals with physical impairments or those taking medications that affect balance or coordination should not be subjected to standard FSTs.

What are some common defenses against DUI charges based on field sobriety test results?
Common defenses include challenging the legality of the traffic stop, the administration and interpretation of the tests, the officer’s training and qualifications, and the individual’s physical or medical conditions. Defense may also argue improper test conditions or use expert testimony to question the reliability of the FSTs.

Can field sobriety test results be the sole basis for a DUI conviction?
While FST results can strongly influence a DUI case, they are typically part of a broader array of evidence that may include chemical tests, officer observations, and circumstantial evidence. However, it is possible for a DUI conviction to be based heavily on FST results, especially if other evidence supports the charges.

How can I prepare for my defense if I've been arrested based on field sobriety test results?
Preparing for your defense should start with consulting a qualified DUI attorney who understands the complexities of DUI cases. Collect any relevant information, including medical records and details about the circumstances of your arrest. Be prepared to discuss all aspects of your case honestly with your lawyer to enable them to build the most robust defense.
