# How is the one-leg stand test administered in Illinois?

The one-leg stand under NHTSA requires the subject to stand with heels together and arms at the sides during instructions, then raise one foot approximately six inches off the ground with toe pointed out, keep the leg straight, look at the raised foot, and count out loud, one thousand one, one thousand two, until told to stop. The test runs for 30 seconds. Scoring counts four clues: swaying, using arms for balance, hopping, and putting the foot down. Two or more clues indicates impairment. Age over 65, weight over 50 pounds overweight, back or leg injury, and inner-ear issues invalidate scoring. A Chicago DUI lawyer compares the video against each NHTSA element.
