Understanding the Exam Format

The HGN test is a part of the standardized field sobriety tests and typically involves the following components:

• Visual Stimulus: A law enforcement officer will position a stimulus, often a pen or small flashlight, about 12-15 inches away from the subject's face.
• Eye Movement Observation: The officer will move the stimulus horizontally, right to left and vice versa, while observing the subject's eye movement for signs of impairment.
• Indicators of Impairment: Officers will look for three primary indicators:

1. Lack of smooth pursuit: The eyes do not follow the stimulus fluidly.
2. Distinct Nystagmus at Maximum Deviation: Involuntary eye movements occur when the eye is held at maximum lateral position.
3. Onset of Nystagmus prior to 45 degrees: Jerking begins before the eye moves 45 degrees away from the center.

• Score Determination: Each eye is assessed separately for six possible clues.

It is imperative to be familiar with the test's procedural nuances, as this will aid in achieving a successful outcome, especially if challenged in a legal context or applied practically.
