Oklahoma DUI Field Sobriety Tests

To make a DUI arrest, law enforcement must have evidence that a driver is intoxicated. To measure the driver's cognitive and physical abilities that can become impaired by alcohol, police often use field sobriety tests. However, there are a number of other factors, other than the influence of alcohol that can affect an individual's performance on these tests.

Types of Field Sobriety Tests

To ensure that they are consistent, the National Highway Traffic Safety Administration (NHTSA) designed three standardized field sobriety tests: the one-leg stand, walk-and-turn, and horizontal gaze nystagmus. Police officers undergo training on how to administer these tests, and the scoring is regulated, though certainly open to bias.

Non-standardized tests are just as the name implies; there are no clear-cut guidelines on administration or scoring. Common examples of these types of tests are reciting the alphabet backwards or touching your fingers to your nose.

No matter which type of test you're asked to perform, the field sobriety tests are relatively subjective. There are also a number of physical or neurological conditions that could make performing the test to the officer's standards very difficult.

Don't Let a Subjective Test Keep You from Fighting a DUI

Even if you "failed" the field sobriety tests, it is still possible to contest your drunk-driving charge. Video tape evidence may show that the test was administered or scored improperly, or medical records may establish that the test results were incorrect.
