Types of Field Sobriety Tests

Field sobriety tests are pivotal tools, testing both physical performance and cognitive functions to detect impairment.

The One-Leg Stand requires a driver to stand on one leg while counting aloud. This test evaluates balance and attention, essential skills for safe driving. During this test, officers observe for swaying, hopping, or using arms to balance, which could indicate intoxication. These subtle cues provide insights into an individual’s functional capacity behind the wheel.

Another popular method is the Walk-and-Turn test. In this examination, individuals must take nine steps, turn on one foot, and return in the same manner, following a straight line. This evaluates a person’s ability to follow instructions and maintain equilibrium, factors crucial in assessing sobriety.

Lastly, the Horizontal Gaze Nystagmus test examines reflexive eye movements. By observing the involuntary jerking of the eyes when following a moving object, officers can glean valuable information about potential impairment. This test relies on physiological responses less within conscious control, thus offering a reliable indicator in discerning levels of intoxication and enhancing public safety.

How Field Sobriety Tests Are Administered

The administration of field sobriety tests begins with an officer’s visual assessment of the suspect, marking a critical initial step in the sobriety evaluation process. This involves ensuring the environment is safe and conducive to conducting the tests properly.

Upon initiation, officers communicate with clear, concise instructions to the individual undergoing testing. This step ensures that the person understands exactly what is required.
