What is a field sobriety test?
Field Sobriety Tests are preliminary tests used by police officers to determine if a driver is impaired. The tests assign tasks that assess the driver’s balance, coordination, and ability to divide attention to more than one task during the field sobriety test. The National Highway Traffic Safety Administration approves three field sobriety tests applied nationally. The tests include the Horizontal Gaze Nystagmus, Walk and Turn, and the One Leg Stand Test.
