The one-leg stand test has a 65 percent reliability factor that a driver is impaired (BAC of .10 or higher) if he or she cannot perform this action during a DUI/DWI stop by law enforcement.
Combined with the walk-and-turn test, reliability is about 80 percent. The driver is asked to stand with one foot raised about six inches. While doing so, s/he must count aloud (one thousand one, one thousand two, etc.) until asked to stop (about 30 seconds).
If you or a family member was pulled over and charged with drunk driving, do not hesitate and contact our highly trained DUI/DWI lawyers for legal help.
