Law enforcement officers use standardized field sobriety tests, including the Horizontal Gaze Nystagmus (HGN) test, Walk and Turn test, One Leg Stand test, and the Walk and Turn test, to assess whether a driver is impaired by alcohol or drugs. These tests evaluate physical coordination, balance, and cognitive function through specific movements like following a stimulus with eyes, walking heel-to-toe along a line, and balancing on one leg while counting. The results, combined with other observations such as slurred speech, dexterity issues, and admission of alcohol consumption, help officers determine if a driver meets the legal threshold for impairment (0.08 BAC in Illinois) and should be arrested for DUI.
