Field Sobriety Tests (FSTs) | What are they? - One Minute Monday

Standardized Field Sobriety Tests are an important piece of the DUI puzzle. The intent of FSTs (Field Sobriety Tests) is for them to be used during the investigation phase and for the findings to be used to help determine probable cause to arrest (for DUI). There are three recognized Standardized Field Sobriety Tests. Horizontal Gaze Nystagmus: This is commonly referred to the "eye test." There are a maximum of 6 clues that can be observed with this test. NHTSA (National Highway Traffic Safety Administration) defines Horizontal Gaze Nystagmus (HGN) is an involuntary jerking of the eyes, as they gaze toward the side. It is the observation of the eyes for HGN that provides the first and most accurate test in the Standardized Field Sobriety Test battery. Although this type of nystagmus is useful in determining alcohol influence, its presence may also indicate use of Dissociative Anesthetics, Inhalants, and other CNS Depressants (DID Drugs). Walk and Turn: This test involves the Defendant walking 9 steps (heel to toe) down a straight line, turning, and coming back, once again walking 9 steps (heel to toe). NHTSA states that "like all divided attention tests, Walk and Turn has two stages." They are: • Instructions stage • Walking stage Both stages are important, because they can affect the subject's overall performance on the test. Whenever possible, the Walk and Turn test should be conducted on a reasonably dry, hard, level, non-slippery surface. There should be sufficient room for subjects to complete nine heel to toe steps. Recent field validation studies have indicated that varying environmental conditions have not affected a subject’s ability to perform this test. The original studies suggested that individuals over 65 years of age or people with back, leg or inner ear problems had difficulty performing this test. Less than 1.5% of the test subjects in the original studies were over 65 years of age. Also, the SCRI studies suggest that individuals wearing heels more than 2 inches high should be given the opportunity to remove their shoes. Officers should consider all factors when conducting SFSTs. One Leg Stand: This balance test involves standing on one leg and balancing (not swaying) for 30 seconds. NHTSA states the following about the One Leg Stand test. Like all divided attention tests, One Leg Stand has two stages. They are: • Instructions stage • Balance and counting stage Both stages are important, because they can affect the subject's overall performance on the test. One Leg Stand is another field sobriety test that employs divided attention. The subject's attention is divided among such simple tasks as balancing, listening, and counting out loud. Although none of these is particularly difficult in itself, the combination can be very difficult for someone who is impaired. For those wanting a longer video on the FSTs, one is in the works! I expect that video to be completed in the next couple of months.
