Which of the following is NOT typically part of the SFST?

The Breathalyzer Test is not typically part of the Standardized Field Sobriety Tests (SFST) because the SFST comprises physical coordination and balance tests conducted on the roadside to assess a driver's level of impairment. The Walk-and-Turn Test, Finger-to-Nose Test, and One Leg Stand Test are specifically designed to evaluate an individual's physical and cognitive abilities, such as balance, coordination, and the ability to follow instructions. In contrast, a Breathalyzer Test analyzes a driver's breath for blood alcohol content (BAC) and is considered a chemical test rather than a physical test. Thus, the Breathalyzer Test serves a different purpose, focusing on chemical analysis instead of observing physical performance, which is the core of the SFST battery.
