Types of Field Sobriety Tests in Oakland, California

Understanding Field Sobriety Tests

When a police officer suspects that a driver is under the influence, they often conduct a series of field sobriety tests (FSTs) to assess the driver’s level of impairment. In Oakland, California, these tests must comply with the standards set forth by the National Highway Traffic Safety Administration (NHTSA), which has identified three approved tests with scientific backing related to DUI impairment. The accuracy of these tests hinges on strict adherence to the established protocol; deviations can impact the reliability of the results.

The Importance of Standardization

Standardized field sobriety tests are structured to provide an objective analysis of a driver’s impairment. At the Law Offices of Nabiel C. Ahmed, our dedicated DUI defense team understands the intricacies of these tests and highlights that errors can lead to wrongful DUI charges. With over a decade of expertise in DUI law, we scrutinize every aspect of the testing protocols to protect your rights and seek justice.

The Three Standardized Field Sobriety Tests

The NHTSA has sanctioned the following three field sobriety tests as reliable to gauge impairment:

1. Horizontal Gaze Nystagmus Test (HGN)

The HGN test measures involuntary eye movements. The officer asks the suspect to focus on a moving object, typically a pen or flashlight, while observing the eyes’ reactions. If the pupil begins to jerk at or before a 45-degree angle, it may indicate a high blood alcohol concentration (BAC). This test has a reported accuracy rate of approximately 77% in determining impairment.

2. Walk and Turn Test

In this test, the suspect must take nine heel-to-toe steps in a straight line, pivot, and repeat the nine steps back. The officer observes for specific indicators of impairment, such as improper steps, loss of balance, or unsteady movement. The walk and turn test claims an accuracy rate of around 68% in detecting intoxication.

3. One Leg Stand Test

During this test, the suspect is instructed to stand on one leg while counting from 1001 to 1030. The officer assesses the suspect for signs of instability, such as swaying or using arms for balance. This test demonstrates about 65% accuracy in indicating impairment.

Additional Non-Standardized Tests

Besides the standardized tests, officers may utilize non-standardized sobriety tests, including:

  • Finger-to-Nose Test
  • Rhomberg Balance Test
  • Hand Pat Test

Importantly, the legitimacy of these non-standardized tests can often be challenged in court, as they lack the same scientific backing and consistency as the standardized tests.
