What is one common method used in field sobriety tests?

The Walk-and-Turn test is a commonly used method in field sobriety tests because it assesses an individual's balance, coordination, and ability to follow instructions, which can be impaired by alcohol consumption. During this test, the subject is asked to take a series of steps in a straight line, heel to toe, and then turn around in a specific manner before returning in the same fashion. This test is effective in evaluating motor skills and is standardized, meaning that it follows specific criteria for each evaluation, allowing law enforcement officers to make consistent observations about potential impairment.

The test is part of a larger battery of assessments designed to gauge whether a person is driving under the influence of alcohol or drugs. Its popularity lies in its relatively straightforward execution and the clear indicators it provides in assessing balance and coordination—two critical abilities that are often affected by intoxication.
