Arizona HGN Practice Test 2026 – Complete Exam Preparation

The Arizona Horizontal Gaze Nystagmus (HGN) test is a key component of field sobriety tests conducted to assess DUI limits and capabilities. Mastering the nuances of this test can be crucial for legal and law enforcement professionals as well as individuals looking to demonstrate understanding in situations requiring sobriety assessment.

Exam Format

The Arizona HGN test involves observing the involuntary jerking of a suspect’s eyes as they follow a stimulus moving horizontally. This physiological response indicates the presence of alcohol or certain drugs. Understanding the evaluation criteria through focused study can significantly improve your test results.

Key Sections:

1. Horizontal Eye Movement Evaluation: Participants are evaluated based on how they track a moving object, such as a pen or flashlight, without head movement.
2. Number of Clues: The test typically identifies several clues, such as a lack of smooth pursuit, to form a composite assessment.
3. Conditions of Testing: Evaluations are carried out in different settings, examining factors like light exposure and subject positioning.

What to Expect on the Test

Participants can expect a series of scenarios that simulate real-world DUI assessments. Practice includes:

• Stimulus Tracking: Following a pen or light as it moves horizontally.
• Identifying Nystagmus: Recognizing the signs of involuntary eye movement at various angles.
• Analyzing Test Conditions: Understanding how environmental conditions can affect results, such as lighting or subject footing.

Components of the HGN Test:

• Smooth Pursuit: Ability for eyes to follow a moving object smoothly.
