What does the term "field sobriety test" refer to in law enforcement?

The term "field sobriety test" specifically refers to a set of tasks that law enforcement officers use to determine if an individual is driving under the influence of alcohol or drugs. These tests are typically administered during a traffic stop when an officer suspects that a driver may be impaired.

Field sobriety tests usually include tasks that assess a person's coordination, balance, and ability to follow instructions. Common examples include the horizontal gaze nystagmus test, the walk-and-turn test, and the one-leg stand test. The performance on these tests helps officers make a determination about whether to arrest the individual for driving under the influence.

Other options do not accurately represent the context in which field sobriety tests are used. For example, assessing if a person is fit for interrogation is unrelated, as is evaluating a suspect’s criminal history; neither pertains to the sobriety of the individual during a traffic stop. Similarly, while field sobriety tests are physical tests, the emphasis is specifically on determining impairment related to the operation of a vehicle, which is why the correct answer centers on the aspect of driving under the influence.
