The Flaws of the Horizontal Gaze Nystagmus Test in DUI Field Sobriety
It is no secret that driving under the influence (DUI) is a serious offense across the United States. Law enforcement officers work tirelessly to identify and apprehend individuals suspected of operating a vehicle while intoxicated. To achieve this, they use various methods, including field sobriety tests. One of the most common tests used by law enforcement is the Horizontal Gaze Nystagmus (HGN) test. However, there are several flaws associated with this method that can lead to wrongful arrests and convictions. In this opinion article, we will discuss the problems with the HGN test and why it's time to consider alternatives to detect DUI.
The Concept of Eye Nystagmus
The HGN test involves a police officer checking for involuntary eye movements that result from alcohol or drug consumption. The concept is relatively simple: the officer moves a pen or a finger in front of the suspect's eyes and checks for horizontal jerking movements. This jerking motion is known as "nystagmus," and it occurs when the eyes move involuntarily. Alcohol or drug consumption can cause nystagmus to occur at smaller angles compared to normal eye movement. While this might seem like a good method to detect DUI, eye nystagmus can occur from several other reasons such as fatigue, vision issues, or even environmental factors, making the results of the HGN test inaccurate.
The Limitations of Equipment and Personnel
The HGN test requires special training, equipment, and the right environmental conditions to work effectively. Even with the necessary equipment, not all officers can perform the HGN test to perfection. Small environmental challenges such as flashing lights, uneven ground, or even high traffic areas can lead to incorrect test results. The officer might observe eye jerks that could be due to other reasons than alcohol or drugs consumption, making the HGN test faulty.
The Complexity of Eye Movements
The process of observing nystagmus involves different categories, including the "resting," "onset" and "maximum deviation." This observation seeks to establish a pattern that indicates the level of alcohol in the suspect's blood. Each of these categories requires a high level of skill and attention to detail to perform accurately. Many officers have been found to cut corners and under-report the angles at which the eye jerks occur, leading to incorrect test results and wrongful convictions.
The Adversarial Nature of the HGN Test
The HGN test is not an easy test to pass. Police officers often position the test along with other similar evaluations to make it more challenging for suspects to pass. The adversarial nature of the test aims to make suspects look guilty and increases the likelihood of a conviction. When suspects fail the HGN test, law enforcement officers can use this as a basis for further investigation and subsequent arrest. This means that many innocent people can find themselves on the wrong side of the law, which is an unfortunate and dangerous outcome.
The Inaccuracy of HGN Test Results
Due to the number of factors that can affect the HGN test, the results it produces are often inaccurate. Light sensitivity, eye strain, fatigue, and pre-existing medical conditions are among many causal factors that can generate false positive results from the HGN test. It is essential to note that the HGN test alone is not enough to prove that a suspect was driving under the influence. However, many police officers have used the results of the HGN test to justify an arrest and follow-up tests that lead to wrongful convictions.
The Need for an Alternative DUI Detection Method
The flaws associated with the HGN test make it necessary to seek alternative DUI detection methods. Several emerging technologies, such as breathalyzers or saliva tests, are more accurate and less prone to errors than the HGN test. While these technologies are not perfect, they offer a better solution to the problem of DUI detection. By advocating for a standardized method and supporting additional research, we can create an environment that is fair to suspects and reduces wrongful convictions.
The Role of a Skilled DUI Defense Attorney
If you have been arrested on suspicion of DUI, it's essential to contact an experienced DUI defense attorney immediately. Some attorneys, like Arja Shah, can evaluate your case and ensure that you get fair and accurate treatment, even if you have conducted the HGN test. Arja Shah understands the complex processes of DUI investigations and can offer meaningful legal counseling that can help you overcome these charges. With the best legal representation available, you can take the first step towards clearing your name and resuming your regular life.
In conclusion, the flaws associated with the HGN test make it a problematic element of DUI detection methods. The test is affected by many factors, including equipment, personnel, and even the test's adversarial nature. As such, many innocent people have suffered wrongful convictions due to a process that is not reliable. It's time to advocate for a system that is more accurate, less invasive, and more fair for everyone involved.
