Standardized Field Sobriety Test Practice 2025 – Complete Exam Prep Guide

The Standardized Field Sobriety Test (SFST) is crucial for assessing sobriety in drivers suspected of being under the influence. Preparing for the SFST can be a game-changer for law enforcement officers. The SFST includes three core tests: the Horizontal Gaze Nystagmus (HGN), the Walk-and-Turn, and the One-Leg Stand. Let's dive into the essentials to understand the test format, content, and strategies for success.

Exam Format

The SFST consists of a series of physical and observational tests designed to assess both motor skills and cognitive functioning. Here’s a breakdown of the core components:

• Horizontal Gaze Nystagmus (HGN): Observes involuntary jerking of the eyes. This test requires the officer to move an object like a pen, side-to-side in front of the suspect's eyes.

• Walk-and-Turn: Involves walking heel-to-toe along a straight line for nine steps, turning, and returning in the same manner. It tests balance, coordination, and ability to follow instructions.

• One-Leg Stand: Requires the individual to stand on one leg for about 30 seconds, testing balance and the ability to count aloud while maintaining composure.

Scoring

Officers score based on how well the suspect follows instructions and performs physical tasks. Each segment includes specific indicators of impairment that are well-documented, allowing officers to draw conclusions about the suspect's sobriety.

What to Expect on the SFST

Expect a realistic simulation of field circumstances where environmental and situational stresses are present. The tests are conducted typically by the roadside or a controlled environment. The officer must take note of:

• Visual cues and physical demeanor.
• Ability to comprehend and execute simple instructions.
• Coordination and balance under slight stress conditions.

Each test must be administered in a standardized manner for the results to be valid.

Tips for Passing the SFST

Preparing for the SFST is vital for any law enforcement professional. Here’s how you can enhance your readiness:

• Understand the Protocols: Familiarize yourself with the detailed procedures and criteria for each test. Knowing these protocols front-to-back ensures you administer them accurately.
