What is the primary purpose of the SFST validation studies?

The primary purpose of the SFST validation studies is to determine the accuracy of the Standardized Field Sobriety Tests at various Blood Alcohol Concentration (BAC) levels, particularly lower BAC levels. These studies play a crucial role in providing empirical evidence that supports the effectiveness of the tests in identifying impaired individuals. By establishing how well the SFSTs function at different BAC levels, law enforcement can make more informed decisions during DUI stops, enhancing the reliability and credibility of the tests used in sobriety determinations.

Other areas, such as improving officer training or assessing public awareness, are certainly important aspects of law enforcement and DUI prevention efforts, but they do not directly address the core function outlined in the validation studies. Evaluating DUI enforcement strategies is also vital for overall effectiveness in combating impaired driving; however, it's distinct from the primary focus on the assessment of the tests' accuracy related to BAC levels. Thus, establishing a foundational understanding of how SFST performs across the spectrum of alcohol impairment is essential for appropriate application in field settings.
