How long should the One Leg Stand test be timed for?

• A. 15 seconds
• B. 30 seconds
• C. 45 seconds
• D. 60 seconds

Answer: (B)

The One Leg Stand test is designed to assess an individual's balance and coordination, which can be affected by alcohol consumption. The standard procedure for this test dictates that it should be timed for 30 seconds. During this period, the subject must stand on one leg while keeping the other leg raised approximately six inches off the ground. The officer observes for signs of impairment, such as swaying, using arms for balance, or putting the raised foot down. Timing the test for 30 seconds allows for a meaningful assessment of the person's ability to maintain their balance under the influence of substances, providing a reliable measure for law enforcement in evaluating suspected DUI cases.
