Field sobriety tests (FSTs) are routinely used by law enforcement officers in Florida to establish impairment in suspected DUI drivers. These tests are designed to assess balance, coordination, and the ability to perform tasks that are often second nature to sober individuals. However, the reliability of these tests can be highly questionable due to the subjective nature of their evaluation and the conditions under which they are administered. This article explores how these tests are conducted, the common grounds on which their results can be contested, and the legal strategies that can be employed to challenge them effectively in court. Understanding the intricacies of field sobriety tests is crucial for anyone facing DUI charges as it can significantly impact the outcome of the case.

Understanding Field Sobriety Tests

Field sobriety tests typically consist of three primary tests: the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. Each test is designed to evaluate different capabilities:

  • HGN Test: Checks for involuntary jerking of the eyes as they follow a moving object, which can be exaggerated by alcohol consumption.
  • Walk-and-Turn Test: Assesses the ability to perform tasks requiring attention, balance, and coordination.
  • One-Leg Stand Test: Measures balance, stability, and the ability to follow instructions.

These tests are standardized by the National Highway Traffic Safety Administration (NHTSA), yet the application can vary significantly between officers and situations. Factors such as road conditions, weather, and the physical condition of the suspect can all influence the results. Misadministration or improper interpretation of these tests can lead to wrongful DUI charges.

Factors Affecting Field Sobriety Test Accuracy

The accuracy of field sobriety tests can be impacted by a wide range of factors that are often overlooked in DUI cases. These include:

  • Environmental Conditions: Poor lighting, uneven road surfaces, and adverse weather conditions can all negatively affect a suspect's performance on sobriety tests.
  • Physical and Medical Conditions: Individuals with physical impairments, injuries, or conditions such as vertigo, poor balance, or neurological disorders may struggle with FSTs regardless of alcohol consumption.
  • Improper Instructions: The officer's failure to provide clear, concise instructions can lead to misunderstandings and poor performance on these tests.
  • Footwear and Clothing: Wearing heels, restrictive clothing, or other inappropriate attire during the test can impede a suspect's ability to perform physical tasks accurately.

Challenging the validity of FST results often involves demonstrating that these external factors influenced the outcome, rather than the suspect's level of intoxication.

Legal Challenges to Field Sobriety Tests

The subjective nature of field sobriety tests provides ample ground for legal challenges. Defense attorneys can argue that the officer's subjective judgment led to a biased interpretation of the test results. The defense can also question the officer's training and experience with field sobriety tests, as well as their ability to administer the tests accurately under pressure or in less-than-ideal conditions.

Furthermore, video evidence from dashcams or body cameras can be crucial in disputing how the tests were conducted and interpreted. This footage can either contradict the officer's report or show that the tests were not administered in a standardized manner as required.

Expert Testimony in Contesting FSTs

In some cases, introducing expert testimony can be a pivotal strategy in contesting the results of field sobriety tests. Experts in fields such as toxicology, human physiology, or traffic safety can provide insights into the unreliability of FSTs and the influence of various factors on a suspect's performance. Expert witnesses can help demonstrate the scientific shortcomings of these tests and how they might not accurately reflect a person's sobriety or lack thereof.

Strategies for Defense Against DUI Charges Based on FSTs

Building a defense against DUI charges that involve field sobriety tests requires a detailed understanding of both the tests themselves and the broader context of the arrest. Defense strategies might include demonstrating that the officer lacked probable cause for initiating the tests, highlighting inconsistencies in the officer’s testimony compared to video evidence, and presenting alternative explanations for the suspect's performance on the tests.
