Understanding the Horizontal Gaze Nystagmus Test

The Horizontal Gaze Nystagmus (HGN) test is a common field sobriety test used by police officers in Maryland to determine impairment from alcohol. It involves observing the eyes of a suspected DUI driver as they follow a moving object such as a pen or flashlight. Although the National Highway Traffic Safety Administration (NHTSA) has standardized this test, it’s not infallible and is subject to human error and external influences.

At Ryan Law LLC, we understand the critical nuances of the HGN test and how it can be improperly administered or interpreted. Our experienced DUI defense attorneys in Harford and Cecil Counties are well-versed in the technicalities and procedural requirements of the HGN test. We meticulously review how your test was conducted to identify any discrepancies or errors that could be leveraged to challenge the results.

Technicalities of the Horizontal Gaze Nystagmus Test

During an HGN test, law enforcement officers look for involuntary jerking of the eyes, which they claim indicates high blood alcohol content. The test must be performed under specific conditions with precise movements and timing to ensure its accuracy. Any deviation from these standardized procedures can significantly affect the test’s reliability and the validity of the arrest. Our defense strategies often involve detailed examination of the officer’s compliance with these protocols during your DUI stop.

Contesting the Validity of HGN Test Results

There are numerous grounds on which the HGN test results can be contested. Factors such as improper test administration, the suspect’s medical conditions, and environmental influences can all impact the reliability of the test results. Ryan Law LLC specializes in identifying and arguing these factors effectively in court, helping to diminish the prosecution’s evidence against you.

Subjectivity and Officer Bias – Arguing that the officer’s subjective judgment affected the test outcome.
Improper Administration – Demonstrating that the test was not conducted following strict NHTSA guidelines.
External Factors – Citing environmental conditions or medical issues that may have influenced the test results.
