Understanding Field Sobriety Tests in Kentucky DUIs
In Kentucky, field sobriety tests (FSTs) play a critical role in cases involving suspected impaired driving. Law enforcement officers use standardized tests to gauge a driver’s impairment level, potentially leading to an arrest for driving under the influence (DUI). These tests, recognized nationally, are based on established procedures by the National Highway Traffic Safety Administration (NHTSA) and aim to provide officers with objective criteria for determining impairment. However, the use of FSTs in Kentucky raises various legal issues, and a knowledgeable attorney can help challenge these tests when they lead to criminal charges.
The Role of Standardized Field Sobriety Tests
Field sobriety tests are designed to help law enforcement officers observe specific physical and cognitive responses in individuals suspected of driving under the influence. In Kentucky, police primarily use three standardized tests: the Horizontal Gaze Nystagmus (HGN), the Walk and Turn (WAT), and the One-Leg Stand (OLS). The Kentucky Court of Appeals has recognized these tests as reliable indicators of impairment when conducted properly. Still, there are stringent protocols that officers must follow to ensure the results are admissible in court, making it critical for defense attorneys to scrutinize FST procedures closely.
Horizontal Gaze Nystagmus Test
The HGN test involves observing involuntary eye movements (nystagmus) that may be more pronounced when an individual is intoxicated. Officers ask the individual to follow a stimulus, usually a pen or flashlight, with their eyes while keeping their head still. Under Kentucky law, for HGN evidence to be admissible, officers must be properly trained, and they must conduct the test under specific guidelines. Defense attorneys often examine the qualifications of the officer administering the test and whether environmental conditions or other factors could have influenced the results.
Walk and Turn Test
The Walk and Turn test assesses both balance and the individual’s ability to follow instructions, both of which may be compromised under the influence of alcohol or drugs. In this test, the suspect is instructed to take nine heel-to-toe steps in a straight line, turn, and then walk back the same way. Officers look for indicators of impairment, such as starting too soon, stepping off the line, and using arms for balance. In Kentucky, courts accept the Walk and Turn as a valid sobriety test, but a defense attorney can challenge results if procedural errors occurred during its administration.
One-Leg Stand Test
In the One-Leg Stand test, the individual is asked to stand on one leg while counting aloud for about 30 seconds. Officers look for signs of impairment like swaying, using arms for balance, hopping, or putting the foot down before completing the test. While the test is generally accepted in Kentucky courts, it may not be suitable for individuals with specific health conditions or balance issues. Defense attorneys can argue that failing the test is not necessarily indicative of impairment, especially if medical issues are present.
Factors That Can Affect Field Sobriety Test Accuracy
Many factors can affect FST results, leading to inaccuracies in determining impairment. In Kentucky, variables like weather conditions, uneven pavement, footwear, physical health, and even stress can impact performance on these tests. As such, courts are increasingly aware of these limitations, and an experienced defense attorney can leverage this awareness to challenge FST evidence in court. By casting doubt on the accuracy of the FSTs, attorneys can argue for reduced charges or even dismissal in certain cases.
Challenging Field Sobriety Test Evidence in Court
Challenging FST evidence involves scrutinizing both the officer’s conduct and adherence to established procedures. Kentucky courts require that all field sobriety tests be administered correctly for the results to be admissible. A skilled attorney will review dashcam footage, question the officer’s training, and investigate external factors that may have influenced test results. Effective challenges can lead to the suppression of FST evidence, which may ultimately weaken the prosecution’s case against the defendant.
