Q: What types of field sobriety tests are commonly used during a DUI investigation in California?
During a DUI investigation in California, law enforcement officers commonly utilize standardized field sobriety tests (SFSTs) to assess a driver’s level of impairment. The three primary tests recognized include the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test.
The HGN test measures the driver’s eye movements in response to a moving object to detect involuntary jerking, which is often correlated with alcohol impairment. The Walk-and-Turn test requires the driver to take a series of heel-to-toe steps along a straight line, demonstrating their balance and ability to follow instructions. Similarly, the One-Leg Stand test involves the driver standing on one leg for a specified duration, further assessing their balance and coordination.
These tests are designed to provide law enforcement with observable evidence of impairment, and refusal to participate in these tests can potentially lead to further legal consequences in California. It is crucial for drivers to understand the purpose and implications of these tests during a DUI investigation.
