standardized field sobriety tests (SFST)
Standardized Field Sobriety Tests (SFST) are specific assessments used by law enforcement to evaluate a person's level of impairment due to alcohol or drugs. These tests typically include tasks such as the Horizontal Gaze Nystagmus (tracking eye movement), Walk-and-Turn (walking in a straight line), and One-Leg Stand (balancing on one leg). SFSTs are designed to be objective and measurable, helping officers determine if a driver is too impaired to operate a vehicle safely. While the results are not definitive proof of intoxication, they provide important evidence in assessing a person's fitness to drive.
