What percentage of correct arrest decisions was shown by the San Diego SFST validation field study based on the 3-test battery?

The percentage of correct arrest decisions shown by the San Diego SFST validation field study based on the 3-test battery is indeed noteworthy. The study found that the correct arrest decisions were at a level of 91%. This indicates a high level of reliability in the SFST when used properly in assessing impairment. The three tests typically involved—horizontal gaze nystagmus, walk-and-turn, and one-leg stand—are designed to provide law enforcement officers with an effective method of evaluating an individual's ability to perform tasks that require physical and cognitive coordination, which can be impaired by alcohol or drugs.

A result of 91% indicates that when officers follow the standardized procedures, they are likely to make informed decisions about sobriety, which is crucial for ensuring public safety and the effectiveness of DUI enforcement. This figure reflects the significance of proper training in conducting these tests and emphasizes the importance of the SFST in reducing drunk driving incidents.
