This blog is the second part of a three part series discussing the standardized field sobriety tests police officers will administer as part of a DC DUI and DWI traffic stop.  The first part discussed the horizontal gaze nystagmus test (or “HGN”).  This part discusses the second test, which is the walk and turn test (“WAT”).

The “WAT” test requires that you walk nine steps heel to toe along a straight line, pivot three steps to turn, and then walk nine steps back heel to toe.  Police officers that NHTSA has certified to administer SFST’s look for eight cues of impairment during this test.  Like with the HGN test, the officers do not tell you what the cues are and they are the sole judge of whether you pass or fail the test.

The three tests consist of the Horizontal Gaze Nystagmus Test (or “HGN”), the walk and turn, and the one leg stand.  The walk and turn and one leg stand in the context of a DC DUI stop will be discussed in the next two posts.  With each test during the DC DUI investigation, the officer looks for specific cues of impairment to determine whether the person passes or fails to test.  Ultimately, if the officer perceives enough “cues” of impairment, he or she will make a DUI arrest.
