The Accuracy of the HGN Test
In previous posts, we’ve covered several standardized field sobriety tests. This week, let’s dive into another one: the horizontal gaze nystagmus (HGN). Georgia law enforcement often relies on this test for those suspected of drugged or drunk driving. But how reliable is it?
What is the HGN Test?
While the walk-and-turn test and the one-leg stand test check for balance issues, the HGN test focuses on the eyes. If you’re not impaired, you should be able to follow an object with your eyes smoothly. But if your eyes bounce or jerk, police might see this as a sign of intoxication.
Performing the HGN Test
To conduct the HGN, an officer will first give verbal instructions and ask if you understand. Then, you’ll be asked to follow an object, like a pen or light, with your eyes. This object is usually held about 12 to 15 inches from your face.
Is the HGN Test Foolproof?
Scientific evidence supports the accuracy of the HGN test. However, it’s not foolproof. Errors in administering the test can lead to invalid results. If you’re a Georgia driver charged with drugged or drunk driving based on HGN or other sobriety tests, you might question the results as part of your defense. An experienced attorney can help you challenge these results and find the best legal course for your situation.
Questioning the Results
The HGN test can be a useful tool for law enforcement, but it’s not without its flaws. If you’ve been charged with DUI based on this test, it’s crucial to seek legal advice. A knowledgeable attorney can help you navigate the complexities of your case and work towards the best possible outcome.
