What is the primary purpose of Standardized Field Sobriety Tests (SFST)?

The primary purpose of Standardized Field Sobriety Tests (SFST) is to determine whether a driver is impaired due to alcohol or drugs. These tests are specifically designed to provide law enforcement officers with observable indicators of impairment that correlate with a driver's ability to operate a vehicle safely. The tests assess various physical and cognitive abilities that can be affected by intoxicants, helping officers make informed decisions about whether a driver is driving under the influence.

SFSTs consist of a series of tasks that test balance, coordination, and cognitive processing. When an officer observes a driver’s performance on these standardized tests, it offers objective evidence regarding impairment, which is crucial in DUI investigations.

Other options do not align with the intentions of SFSTs. Assessing driving knowledge, evaluating vehicle conditions, or checking for seatbelt compliance falls outside the scope of SFSTs, which are focused solely on detecting signs of alcohol or drug impairment in drivers.
