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). The SFST comprises three primary tests designed to assess a person's level of impairment due to alcohol: the Walk-and-Turn Test, the One Leg Stand Test, and the Horizontal Gaze Nystagmus Test.

These field sobriety tests are performed on the roadside and rely on observable physical indicators of impairment, such as balance, coordination, and the ability to follow instructions. The Breathalyzer Test, however, is a chemical test used to measure the blood alcohol concentration (BAC) in a person’s breath and is conducted using specific devices at a police station or location where the equipment is available, rather than as part of the initial field sobriety assessments.

This distinction is important, as the SFSTs provide immediate observations that officers can use to determine whether further testing, such as a Breathalyzer, is needed based on the initial performance on these physical tests.
