The Horizontal Gaze Nystagmus Test in DUI Field Sobriety: What You Need to Know and How a DUI Defense Attorney Can Help

The Benefits of Hiring a DUI Defense Attorney When Dealing with the Horizontal Gaze Nystagmus Test

Driving under the influence (DUI) is a serious criminal offense that carries significant penalties, including hefty fines, license suspension, and even jail time. For this reason, it's important to understand the various tests and procedures that law enforcement officers use to determine if a driver is impaired. One of the most commonly used tests is the Horizontal Gaze Nystagmus (HGN) test, which is designed to detect impairment by measuring involuntary jerking of the eyes. While the HGN test can be accurate, it's not foolproof, and there are several factors that can affect the results. This article explores the HGN test, its limitations, and the benefits of hiring a skilled DUI defense attorney like Arja Shah to guide you through the process.

What is the Horizontal Gaze Nystagmus Test?

The HGN test is used to evaluate a person's level of impairment when driving under the influence of alcohol or drugs. During the test, a law enforcement officer will instruct the driver to follow a moving object (typically a pen or finger) with their eyes while keeping their head still. As the eyes move from side to side, the officer will observe whether the eyes jerk involuntarily. In individuals who are impaired, the eyes will jerk earlier and more distinctly. The test is designed to measure several factors, including the angle of onset of the jerking, the smoothness of the eye movement, and the number of jerks that occur.

Limitations of the HGN Test

While the HGN test is often used to identify drivers who may be under the influence, it's important to note that the test is not infallible. There are several factors that can affect the results of the HGN test, including:

• Medical conditions such as epilepsy or vertigo
• Poor lighting conditions or glare
• Adverse weather conditions such as wind or rain
• Interference from traffic or other visual distractions
• Misconduct or incompetence on the part of the officer administering the test

In addition, some medications and medical conditions can cause the eyes to jerk, leading to a false positive on the test. For this reason, it's important to consult with an experienced DUI defense attorney if you have been charged with a DUI based on the HGN test.

By hiring an experienced DUI defense attorney, you can ensure that your rights are protected and that you receive the best possible defense against the charges against you.
