Field sobriety tests are designed as roadside evaluations to help officers determine if a driver is under the influence. Common tests include the walk-and-turn, one-leg stand, and horizontal gaze nystagmus assessments. While these tests can provide indicators, they are not foolproof and can be affected by health issues, environmental conditions, and nervousness.
Knowing the proper procedures and potential flaws in these tests is crucial when defending against DUI charges. An experienced attorney can examine the circumstances surrounding your test administration and identify any violations or errors. This knowledge allows for informed decisions and effective advocacy in your case.
Field sobriety tests are a series of physical and cognitive tasks administered by police officers to evaluate a driver’s impairment. These tests assess balance, coordination, and eye movement to detect signs consistent with intoxication. Although widely used, their accuracy can vary, and they are often subjective. Understanding their purpose and limitations is fundamental to addressing DUI allegations.
The primary field sobriety tests include the horizontal gaze nystagmus (HGN), walk-and-turn, and one-leg stand tests. Officers observe specific indicators such as involuntary eye jerking, inability to maintain balance, or incorrect task performance. The administration must follow standardized protocols to ensure validity. Any deviations can impact the test’s reliability and the strength of the prosecution’s case.
