Residents in Arizona who are suspected of driving under the influence may be asked to take a field sobriety test. Matthew Lopez Law is here to discuss the difference between the standardized and non-standardized versions of these tests.
Field sobriety tests come in two forms: standardized and non-standardized. Generally speaking, you will likely be given a standardized test. This is because these tests have standards set by the National Highway Traffic Safety Administration. Since there is official agreement on how to judge the results of these tests, they are more consistent and thus used more often in court.
However, it should be noted that even standardized field sobriety tests are not considered fool-proof. More often than not, they are used as supplementary material to help support already existing evidence in a case.
Some examples of non-standardized tests can include reciting the alphabet backwards, counting down from a high number, the hand pat test, or the Rhomberg balance test. There are only three standardized tests by comparison. They are the walk-and-turn test, the horizontal gaze nystagmus test, and the one-leg stand test.
Regardless of whether they are standardized or non-standardized, these tests aim to check your balance, mobility, ability to multitask, and ability to follow instruction. All of these would be difficult for you to display fine control over if you were under the influence.
