North Carolina Criminal Law Updates
Field sobriety tests (FSTs) and Standardized Field Sobriety Tests (SFSTs) are common tools law enforcement officers use to 
determine if a driver is driving under the influence of drugs or alcohol.
These tests are designed to measure a driver’s physical and cognitive abilities, and assess their level of impairment.
If an officer suspects that a driver is impaired, they may ask them to perform one or more FSTs as part of a DUI investigation.
