What are field sobriety tests used for?

On Behalf of | Jan 16, 2018 | Criminal Defense |

After an arrest for suspected drunk driving in Mississippi, you are no doubt wondering if there is any way that you can defend yourself against the charges you now face. Just like with any criminal charge, it is important for you to remember that you are innocent until proven guilty. During your arrest process, you were likely asked to participate in some activities and tests. You might have thought that these things were meant to prove that you were drunk. That, however, is not necessarily the case.

When it comes to the one-leg stand test, the walk and turn test and the eye test, FieldSobrietyTests.org indicates that these tests not only are not meant to prove your intoxication but they are actually unable to do so. Instead, these tests are intended to indicate that you might be drunk and therefore to give law enforcement officers the legal right to place you under arrest.

Each of the three field sobriety tests approved for use has a known level of inaccuracy as well. The accuracy rates for these tests individually run between 77 percent on the high end to 65 percent on the low end. Even when you are instructed to take all three tests, the accuracy rate of them combined does not exceed 82 percent.

This information is not intended to provide legal advice but is instead meant to let residents in Mississippi know exactly what the purpose of field sobriety tests used in a drunk driving investigation is and how accurate these tests might be.
