What You Must Know About Field Sobriety Tests

Police officers often use field sobriety tests after driving under the influence (DUI) stops. The three most common are the one-leg stand, the walk-and-turn and the horizontal gaze nystagmus (HGN) tests. Often, all three will be used together.

At Swain Law Group, our Norman defense attorneys have years of experience defending drivers against DUI charges, and they understand the ins and outs of the law. They will offer an aggressive, well-prepared defense and help you look into your legal options. This is especially important because our lawyers know the common issues with field sobriety tests – including how they are far less accurate than many people assume.

How Accurate Are Field Sobriety Tests?

Studies have found that the HGN test is only 77% accurate – and that is the most accurate of the three. The one-leg stand test is only 65% accurate, and the walk-and-turn test is just 68% accurate.

In other words, if you take these tests, you will most likely fail them – even if you are sober. People often fail because they are fatigued or confused, or because the officer makes a mistake when administering the test. This type of testing is not a reliable way to judge intoxication, even though it is so widely used.

Additionally, field sobriety tests are not mandatory in Oklahoma. You do not have to take them and risk a failure, which could put your case in jeopardy. You can refuse the tests, and the police cannot legally use that refusal alone as a reason to arrest you.
