Can You Refuse a Field Sobriety Test in Kentucky?

Your Right to Refuse Field Sobriety Tests in Kentucky

If you are pulled over on suspicion of DUI in Kentucky, the officer will likely ask you to perform standardized field sobriety tests. Many drivers do not realize that they have the right to refuse these tests. Understanding your rights regarding field sobriety tests can make a significant difference in the outcome of a DUI case. The DUI defense attorneys at Clark + Harris explain your rights and help drivers in Lexington, Louisville, and throughout Kentucky make informed decisions when confronted with a DUI investigation.

What Are Standardized Field Sobriety Tests?

The standardized field sobriety tests used by law enforcement in Kentucky consist of three exercises developed by the National Highway Traffic Safety Administration. The Horizontal Gaze Nystagmus test involves the officer moving an object such as a pen or finger back and forth in front of your eyes while watching for involuntary jerking of the eyeball. The Walk and Turn test requires you to walk nine steps heel-to-toe along a straight line, turn, and walk nine steps back while the officer observes your balance, coordination, and ability to follow instructions. The One Leg Stand test requires you to stand on one leg with the other foot approximately six inches off the ground while counting for 30 seconds.

These tests are designed to detect impairment, but they are far from perfect. Research has shown that even the most accurate field sobriety test, the Horizontal Gaze Nystagmus test, is only about 77% accurate at identifying drivers above the legal limit. The Walk and Turn test is approximately 68% accurate, and the One Leg Stand test is approximately 65% accurate. This means that a significant percentage of sober drivers will fail these tests.

Can You Legally Refuse Field Sobriety Tests?

Yes, you can refuse to perform field sobriety tests in Kentucky. Field sobriety tests are voluntary, and there is no legal penalty for refusing to perform them. Unlike the implied consent law that applies to breathalyzer and blood tests under KRS 189A.103, there is no statute that penalizes drivers for refusing field sobriety tests. You will not lose your license, face additional charges, or receive any other legal penalty specifically for refusing these tests.

However, it is important to understand that refusing field sobriety tests does not prevent the officer from arresting you for DUI. If the officer has other evidence of impairment, such as the odor of alcohol, slurred speech, bloodshot eyes, or erratic driving, they may still have probable cause to arrest you and request a breathalyzer or blood test.

Should You Refuse Field Sobriety Tests?

The decision to refuse field sobriety tests involves weighing the potential risks and benefits. In many cases, performing field sobriety tests provides the prosecution with additional evidence of impairment that they would not otherwise have. Even if you perform the tests reasonably well, the officer may note small errors or deviations that are characterized as signs of impairment in their report. On the other hand, politely declining to perform the tests prevents the officer from obtaining this subjective evidence.

There are many reasons why a completely sober person might perform poorly on field sobriety tests. Medical conditions affecting balance, leg or back injuries, inner ear problems, neurological conditions, age, weight, fatigue, anxiety from the police encounter, weather conditions, poor lighting, uneven road surfaces, and even the type of shoes you are wearing can all affect your performance on these tests.

Field Sobriety Tests vs. Breathalyzer Tests: Know the Difference

It is crucial to distinguish between field sobriety tests and chemical tests such as breathalyzer or blood tests. While field sobriety tests are voluntary with no legal penalty for refusal, Kentucky’s implied consent law under KRS 189A.103 applies to chemical tests. Under implied consent, by operating a motor vehicle in Kentucky, you have impliedly consented to submit to chemical testing if an officer has reasonable grounds to believe you are driving under the influence. Refusing a chemical test can result in automatic license suspension and other consequences. This is a completely separate issue from field sobriety test refusal.
