What is the purpose of the walk and turn test in OUI assessment?

The walk and turn test is specifically designed to assess balance and coordination in individuals suspected of operating under the influence (OUI). During this test, a subject is asked to walk in a straight line, typically heel to toe, and then turn around and walk back. The key elements evaluated include the subject's ability to maintain stability while walking, their ability to follow instructions, and their physical coordination during the task. Successfully completing this test requires a combination of physical and mental skills, making it a useful tool for law enforcement officers in assessing whether the individual may be impaired due to intoxication. Thus, the primary purpose of this test is to evaluate how well a person can balance and coordinate their movements when tasked with a simple physical activity.
