What clues might indicate impairment during the walking stage of the walk and turn test?

During the walk and turn test, impairment can often be observed through specific behaviors exhibited by the subject. Focusing eyes straight ahead typically indicates a level of composure and focus expected in a sober individual, not impairment. Stopping at the midpoint suggests a disruption in the planned movement, which could indicate a lack of coordination or balance.

However, the action of failing to turn properly is a significant indicator of impairment. This aspect of the test is designed to assess how well a person can execute a simple series of movements. A proper turn requires balance and coordination; any failure to do this successfully can suggest that the individual is experiencing impairment, possibly due to alcohol or other substances.

In summary, the key behavior that illustrates impairment during the walking stage is the failure to turn properly, as it demonstrates a breakdown in executing the task, which is integral to evaluating a person's physical and cognitive faculties.
