What is the maximum number of clues that can be observed during the One Leg Stand test?

The One Leg Stand test is a standardized field sobriety test used by law enforcement to assess a person's level of impairment. During this test, the individual is instructed to stand on one leg while counting aloud for thirty seconds. Law enforcement officers observe specific clues to determine if the individual is impaired.

The maximum number of clues that can be observed during the One Leg Stand test is four. These clues include swaying while balancing, using the arms for balance, hopping to maintain balance, and putting the foot down, among others. Each of these behaviors indicates a lack of coordination and potentially suggests impairment due to alcohol or drugs.

Identifying and assessing these clues helps officers make informed decisions about whether a person may be driving under the influence. The structured nature of this test and the clear criteria for what constitutes a clue are essential for maintaining consistency and reliability in assessments of impairment on the road.
