Field sobriety test accuracy rates

If you find yourself facing criminal charges for allegedly driving under the influence of alcohol in New Jersey, it is important for you to learn about the facts that may be used to support a conviction by the prosecution team. These include the outcomes of the standardized field sobriety tests that are administered at the location of your stop and before you are arrested.

It is true that if a police officer deems you to have failed one or more of these tests, you may be arrested and charged with drunk driving. It is not true, however, that the results of any of these tests can ever prove that you were drunk at the time. As explained by, the purpose of these tests is simply to provide enough evidence so that an officer has the legal right to place you under arrest.

It is a known fact that all three of the field sobriety tests have known inaccuracy rates. The least accurate of all is the one-leg stand test with an accuracy rate of only 65%. The walk-and-turn test is said to be 68% accurate. The eye test has the highest accuracy rate at 77%. Several physical, emotional or mental health conditions have been known to contribute to failures of these tests.

If you would like to learn more about the type of evidence that may be used against you after you have been arrested for suspected drunk driving, please feel free to visit the field sobriety test page of our New Jersey criminal defense website.
