Q: What is a Field Sobriety Test?
A Field Sobriety Test (FST) is a series of on-site tests conducted by law enforcement to assess a person’s level of impairment due to alcohol or drugs. These tests are typically administered during a traffic stop when an officer suspects a driver is under the influence. The purpose of FSTs is to evaluate a driver’s physical and cognitive abilities, which can help determine whether they should be arrested for Driving Under the Influence (DUI).
There are several standardized FSTs that officers generally administer, including the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. Each of these tests assesses specific skills such as balance, coordination, and the ability to follow instructions. The results of these tests can be subjective, as they rely on the officer’s observations and the performance of the individual being tested.
In California, it is important to note that individuals have the right to refuse field sobriety tests. However, refusing these tests may lead to the assumption of impairment and can result in arrest and further legal consequences. The use and interpretation of FSTs can also play a significant role in DUI cases, as the results may be used as evidence in court to establish impairment.
