• A. 20
• B. 25
• C. 30
• D. 35

Answer: (C)

The One Leg Stand test is a field sobriety test used by law enforcement to evaluate a subject's balance and coordination, which can be affected by alcohol or drugs. For this test, the subject is instructed to raise one foot approximately six inches off the ground and to maintain that position for a specific amount of time. The correct duration for which the subject must keep their foot raised is 30 seconds. This time frame allows the officer to observe the subject's ability to maintain balance while also paying attention to indicators of impairment, such as swaying, using arms for balance, or putting the foot down. The 30 seconds provides a sufficient assessment window to gather relevant data about the subject’s motor skills and potential impairment, making it a standard component of evaluating sobriety in a roadside situation.
