Field sobriety tests not always accurate

On Behalf of | Dec 26, 2017 | DWI Defense |

If you have been arrested and charged with a drunk driving offense in Texas, you may understandably be scared and upset and very worried about what might happen to you. The impact of a drunk driving conviction can be emotionally and financially tough on drivers. However, it is important for you to know that you have rights and there may be ways to defend yourself against the charges you face.

One of the options for a potential defense to a driving while intoxicated charge is to challenge the accuracy of the field sobriety tests that were administered before your arrest. Each of the three tests used has a known rate of inaccuracy associated with it. Many physical and neurological conditions can make it all but impossible for you to pass at least one of these tests even if you have not been drinking. If you have a hip, leg or knee injury you may not able to balance well on one leg for example.

The one-leg test has the lowest accuracy rate at 65 percent and the walk-and-turn test is close at 68 percent. The eye test that measures a involuntary motion in your eye is the most accurate but even that accuracy rate is only 77 percent. 

If you would like to learn more about the accuracy rate of drunk driving investigation tests and what factors may interfere with a person’s ability to pass these, please feel free to visit the field sobriety test page of our Texas drunk driving criminal defense website.
