What is the one-leg stand test?

You raise one foot roughly six inches, keep the leg straight with the toe pointed, look at your foot, keep your arms at your sides, and count aloud until told to stop. Thirty seconds.

Four clues: swaying, using arms for balance, hopping, and putting the foot down. Two is the decision point.

The problems with this one are physical and documented. The training material itself acknowledges that people over 65, people significantly overweight, and people with back, leg, or inner-ear conditions may have difficulty regardless of sobriety. Footwear matters — heels above a certain height are supposed to be removed. Surface matters considerably.

Thirty seconds is also longer than it sounds. Try it sober, in the dark, on a slope, on camera, with an armed officer watching and traffic passing. Most people are surprised.

If you have any injury or condition affecting balance, that fact should reach your attorney early.
