Standardized Field Sobriety Test (SFST) Practice Test 2025 - Free SFST Practice Questions and Study Guide

The SFST is designed not only to evaluate alcohol impairment but also to assess impairment due to drugs and other substances. It includes specific tests such as the horizontal gaze nystagmus, walk-and-turn, and one-leg stand, which can reveal signs of impairment regardless of the substance involved.

Research indicates that certain patterns in a person's performance on these tests can correlate with impairment from various types of drugs, including but not limited to narcotics, stimulants, and depressants. Therefore, while the SFST was originally developed to analyze alcohol impairment, its utility extends beyond that, making it a valuable tool for law enforcement in identifying drivers impaired by various substances.

This broader application is crucial within the context of rising concerns about drugged driving, illustrating the SFST's relevance in accommodating various forms of impairment, not just those related to alcohol consumption.
