What is the maximum duration for the One-Leg Stand test?

The One-Leg Stand test is a standardized field sobriety test used by law enforcement to assess a suspect's level of impairment. The maximum duration for this test is set at 30 seconds. During the test, the individual must stand on one leg while maintaining balance, with the other leg elevated approximately six inches off the ground. The officer observes for signs of impairment, including swaying, using arms for balance, and the inability to maintain the position for the full duration of the test.

This 30-second timeframe is critical for achieving a reliable assessment of the individual’s coordination and balance, two skills that are often compromised by alcohol consumption. It also allows enough time for the officer to effectively evaluate reactions and maintain the integrity of the test under field conditions. In contrast, the options that suggest shorter or longer durations do not align with the established protocols for this specific field sobriety test.
