During the walk and turn test, if a subject steps off the line twice and raises their arms, how many clues have they shown?

In the walk and turn test, each specific action or mistake demonstrated by the subject is categorized as a "clue" indicating potential impairment. In this scenario, stepping off the line twice is counted as two separate clues, since each instance of stepping off demonstrates a lack of balance or coordination. Additionally, raising the arms while walking is considered another clue, as it is a compensatory action that suggests difficulty in maintaining balance.

Therefore, with the subject stepping off the line twice contributing two clues and raising their arms providing yet another clue, a total of three clues is identified. The correct answer reflects the accumulation of these observations during the test. This understanding is crucial for accurately assessing the performance in field sobriety tests, where multiple indicators help determine a subject's impairment level.
