What are Standardized Field Sobriety Tests?
Field Sobriety Tests (FSEs) are so-called divided-attention tests used by an officer who has stopped a driver for DUI to assess the driver’s physical and/or mental impairment. The standardized Field Sobriety Tests include Horizontal Gaze Nystagmus (the eye test), the Walk and Turn Test, and the One Leg Stand test. The following information on the FSTs comes from the research and training materials of the National Highway Traffic Safety Administration (NHTSA).
