Drunk driving tests not 100% accurate

If you have been arrested for and charged with a suspected driving under the influence of alcohol charge in Virginia, you will want to learn as much as you can about the elements that may be helpful in your defense. One of the things you should educate yourself about is the tests administered by officers prior to placing you under arrest. These are commonly called field sobriety tests.

As explained by FieldSobrietyTests.org, each one of the three standardized tests has a known inaccuracy rate. That means that the results of the tests may not always be correct. In fact, your emotional, mental or physical health conditions may make it all but impossible for you to pass one or all of these tests even if you have not consumed alcohol.

The eye test has a 77% accuracy rate but some neurological conditions might produce results that an officer inappropriately assumes is due to impairment by alcohol. The one-leg stand test and the walk and turn test have accuracy rates of 65% and 68%, respectively. The results of these tests may be negatively impacted by a person's weight or age. People who have inner ear problems or issues with their legs, back, knees or feet may not be able to balance sufficiently to pass these tests.

If you would like to learn more about the factors that may contribute to your inability to pass a roadside test during a drunk driving investigation, please feel free to visit the field sobriety testing page of our Virginia criminal and drunk driving defense website.
