Walk and Turn Field Sobriety Test

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

These 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 walk-and-turn test, the other tests that make up the SFST are the horizontal gaze nystagmus (HGN) and the one-leg stand tests.
