Being asked to perform a field sobriety test can be an intimidating and nerve-wracking experience regardless of whether a person is intoxicated or not. One reason field sobriety tests can evoke fear or trepidation in a driver is because the tests can lead to drunk driving charges in Tennessee. These charges can come about if an officer decides a motorist has failed the test. However, a motorist could fail the test for reasons that have nothing to do with intoxication.
One's physical condition can play a significant role in the outcome of a field sobriety test. For example, if a person has bad knees or ankle problems, any part of the test requiring balance or walking straight may be challenging. Weight can be an issue also. Another physical factor is attributed to age. It may simply be too difficult for an elderly person to perform tasks on demand.
Outside factors may influence the outcome of a field sobriety test. An officer performing the test must be trained to administer it properly. Also, the fact that the results are subjective can make this kind of test of intoxication anything but scientific.
When a field sobriety test result has led to an arrest and charges for a Tennessee motorist, that motorist may benefit by gaining an understanding about the nature of the testing and how it can be used as evidence. An experienced legal representative can examine the details of any given test and assess whether outside factors or physical factors may have played a role in the results reported.
