What is the outcome of failing an SFST?

When an individual fails a Standardized Field Sobriety Test (SFST), the typical outcome involves the requirement of further tests, such as a breathalyzer or chemical test. Failing an SFST indicates apparent impairment, which is often used by law enforcement as probable cause to conduct additional testing to determine the driver's blood alcohol concentration (BAC) or the presence of drugs.

While there may be legal consequences, such as arrest or citation, the immediate directive following a failure is the need for further tests to establish a more definitive understanding of impairment. Other options, such as mandatory driver's education or no repercussions, do not align with the protocol typically followed in response to SFST results.
