Field Sobriety Tests (FSTs) are a common tool used by law enforcement officers to determine if a driver is under the influence of alcohol or drugs. However, these tests have been criticized for their lack of accuracy and reliability. In this blog post, we will explore the limitations of FSTs and provide tips on how to challenge their results in your DUI defense.
Understanding the Limitations of Field Sobriety Tests
Field Sobriety Tests are designed to assess a person's physical and cognitive abilities, which can be impaired by alcohol or drugs. There are three standardized FSTs: the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. However, these tests have several limitations:
- Subjectivity: The results of FSTs are often based on the officer's subjective interpretation of the driver's performance. This can lead to inconsistencies and potential bias.
- Accuracy: According to the National Highway Traffic Safety Administration (NHTSA), FSTs have an accuracy rate of only 65-77%. This means that a significant number of drivers may be falsely identified as impaired.
- Medical Conditions: Certain medical conditions, such as neurological disorders, can cause a person to fail an FST even if they are not under the influence of alcohol or drugs.
- Environmental Factors: Poor weather conditions, uneven surfaces, and inadequate lighting can all affect a person's performance on an FST.
Challenging Field Sobriety Test Results in Your DUI Defense
If you have been charged with a DUI and believe that the results of your FST were inaccurate or improperly administered, there are several ways to challenge the evidence in court:
- Question the Officer's Training and Experience: In order to administer FSTs properly, officers must undergo specific training. You can question the officer's qualifications and experience in administering the tests, and if they followed the proper procedures.
- Present Evidence of Medical Conditions: If you have a medical condition that could have affected your performance on the FST, you can present this evidence in court to challenge the results. This may include medical records, expert testimony, or even a demonstration of the condition.
- Highlight Environmental Factors: If your FST took place in poor conditions, you can argue that these factors contributed to your poor performance. For example, if the test was conducted on an uneven surface or in heavy rain, this could have affected your balance and coordination.
- Request a Suppression Hearing: If you believe that the officer did not have reasonable suspicion to conduct the FST, you can request a suppression hearing to have the evidence excluded from your case. This may involve arguing that the officer did not follow proper protocol or that the initial traffic stop was unjustified.
