Is the one-leg stand test accurate?

If you are ever suspected of driving under the influence of alcohol in Arizona, a law enforcement officer might ask you to participate in field sobriety tests. While these tests do not conclusively prove that you are drunk or establish a specific blood alcohol content, they may be used to establish sufficient cause to place you under arrest. One of the tests used is called the one-leg stand test.

As explained by, this particular test is only believed to be 65-percent accurate. There are several factors that may interfere with your ability to successfully pass this test even if you have not been drinking. People who are overweight or elderly, for example, may naturally have problems balancing successfully as required by this test. So too will people who have inner ear or other conditions that naturally hinder balance. Even the shoes that you are wearing may cause problems for you when trying to perform this test.

Successful performance of this test requires that you lift one foot about six inches from the ground, stare intently at it and count in a one-one-thousand, two-one-thousand pattern until the officer tells you to stop. You must also keep your arms and hands by your sides without using them for balance in any way. Even a slight swaying or placement of your raised foot down even for a moment could be things that are used to determine your failure of the test.
