In past weeks, we have discussed the three types of field sobriety tests sanctioned by The National Highway Traffic Safety Administration (NHTSA) that comprise the Standardized Field Sobriety Test (SFST): the horizontal gaze nystagmus test, the one-leg stand test, and the walk-and-turn test. This week, we will examine the Walk and Turn test in greater detail.

NHTSA research indicates that 79 percent of individuals who exhibit two or more indicators in the performance of the test will have a BAC of 0.08 or greater (Stuster and Burns, 1998).
