If you were asked to submit to testing, one of the tests you likely took was called a walk-and-turn test. FieldSobrietyTests.org explains that this is one of three standardized tests sanctioned for use by the National Highway Traffic Safety Administration. Contrary to what you and others may think, however, none of the field sobriety tests are indicated to prove that you were in fact drunk at the time of your arrest. Instead, they are only meant to give enough support to the fact that you might be intoxicated so that officers can legally arrest you.
The walk-and-turn test requires you to take nine paces in a heel-to-toe manner and count each step as you take it. Any loss of balance or use of your arms to balance could be used as signs that you may be intoxicated. The accuracy rate of this test is said to be a mere 66 percent.
