One Leg Stand Sobriety Test

The One Leg Stand Field Sobriety Test is one of the three tests of the Standardized Field Sobriety Test (SFST) in the USA. This test is not part of the usual tests of fitness for athletes, but is similar to the stork balance test and may be a useful alternative.

These sobriety tests, which were developed in the 1970s, are performed during a traffic stop in order to determine if a driver is impaired. As well as the One Leg Stand test, the other tests that make up the SFST are the horizontal gaze nystagmus (HGN) and the Walk and Turn tests.
