Arizona Horizontal Gaze Nystagmus (HGN) Practice Test

The Arizona Horizontal Gaze Nystagmus (HGN) Test is a critical component of field sobriety assessments utilized by law enforcement agencies across the state. This test evaluates the involuntary movement of a person's eyes to help determine impairment. Preparing for this test through our specialized quiz can enhance your understanding and ability to navigate Arizona's legal landscape effectively.

Understanding the HGN Exam

The HGN test is often administered as part of a trio of field sobriety tests, which also include the Walk-and-Turn and One-Leg Stand tests. It measures the involuntary jerking of the eyes as they gaze to the side, a reaction that becomes exaggerated when an individual is intoxicated, primarily due to alcohol consumption.

Exam Format

• Conducted by Law Enforcement: The test is typically performed by a trained officer in the field.
• No Paperwork Involved: Unlike written exams, this test is observational and requires the subject to follow the officer's stimulus, such as a pen or the officer’s fingertip.
• Three Stages:

1. Smooth Pursuit: Observing the ability to follow a moving object smoothly.
2. Nystagmus at Maximum Deviation: Holding the gaze at maximum deviation to the side and observing for any involuntary movement.
3. Onset of Nystagmus Prior to 45 Degrees: Checking if nystagmus begins before the eyes reach a 45-degree angle.

What to Expect on the HGN Test

When you undergo the HGN test, you can expect:

• Close Observation: The officer will closely observe your eye movements without requiring physical contact.
• Immediate Results: Results are apparent during the test and are often combined with observations from the other field sobriety tests to make a DUI charge decision.
• Objective Measurement: The test relies on physiological responses that are hard to consciously control, thus providing officers with a reliable measure of impairment.

Tips for Studying and Passing the Arizona HGN Test

• Acquaint Yourself with Test Protocols: Understanding how the test is administered can reduce anxiety and increase your comfort level during the assessment.
