What type of field sobriety test is the Walk-and-Turn classified as?

The Walk-and-Turn test is classified as a divided attention test because it requires the individual to process multiple stimuli simultaneously and manage competing cognitive and physical tasks. During this test, the person must focus on walking a straight line while also listening to instructions and maintaining balance. This dual-tasking aspect evaluates the subject's ability to split their attention between physical coordination and mental processing, which can be impaired by intoxication. Additionally, performance on this test can reflect the individual's ability to follow directions and their overall state of mental alertness, both of which are affected when under the influence of alcohol or drugs.
