What percentage of the time did the Colorado SFST validation study show corrected arrest decisions based on the 3-test battery?

The correct answer indicates that the Colorado SFST validation study demonstrated a high level of accuracy in arrest decisions based on the three-test battery, with 93% of the time leading to correct outcomes. This suggests that when law enforcement officers administered the standardized field sobriety tests (including the horizontal gaze nystagmus, walk-and-turn, and one-leg stand), they were able to make informed and accurate judgments regarding a driver's level of impairment.

The significance of a high percentage like 93% underscores the reliability of these standardized tests in evaluating intoxication levels, which is crucial for justifying arrest decisions and ensuring public safety. This level of accuracy highlights the effectiveness of the SFST methodology and reinforces its use in fields related to DUI enforcement and traffic safety.
