Field sobriety tests (FSTs) are often used by law enforcement officers to determine if a driver is impaired due to alcohol or drugs. While these tests may seem straightforward, they have several limitations. Understanding these limitations is crucial for building a strong defense against DUI charges. In this blog post, we will discuss the limitations of field sobriety tests and provide tips on how to challenge their results in court.
1. The Subjectivity of Field Sobriety Tests
One of the main limitations of FSTs is their subjectivity. Officers often rely on their own judgment when administering and interpreting these tests, which can lead to biased or inaccurate results. For example, the Horizontal Gaze Nystagmus (HGN) test involves observing a suspect's eye movements as they follow a moving object, such as a pen or flashlight. However, an officer's interpretation of the test can be influenced by their training, experience, and personal biases.
To challenge the subjectivity of FSTs, it's essential to examine the officer's training and qualifications in administering the tests. Additionally, hiring an expert witness to review the test results and provide an unbiased opinion can help strengthen your defense.
2. The Impact of Medical Conditions on FST Results
Another limitation of FSTs is that certain medical conditions can affect a person's ability to perform the tests, leading to false-positive results. For example, individuals with inner ear disorders or neurological conditions may have difficulty maintaining balance during the one-leg stand or walk-and-turn tests. Similarly, some medications can cause nystagmus, leading to a false-positive result on the HGN test.
To challenge FST results based on medical conditions, it's crucial to gather medical records and consult with medical experts who can testify about the impact of these conditions on the test results. This can help demonstrate that the FST results were not a reliable indicator of impairment.
3. The Influence of Environmental Factors on FST Performance
Environmental factors can also impact the accuracy of FST results. Poor lighting, uneven surfaces, and inclement weather can make it difficult for a suspect to perform the tests accurately. Additionally, the stress and anxiety of being pulled over and subjected to a field sobriety test can affect a person's ability to perform the tests.
To challenge FST results based on environmental factors, it's essential to gather evidence about the conditions at the time of the test. This can include photographs, video footage, or witness testimony. Additionally, expert witnesses can help explain how these factors may have affected the test results.
