Field Sobriety Tests in Dallas
Dallas Defense Lawyer Skilled at Challenging Field Sobriety Tests
After a driver is suspected of DWI in Dallas, there are two types of tests they will be asked to consent to, the breath test and the field sobriety tests. Field sobriety tests are coordination-based tests that are used by law enforcement to determine if people are under the influence of drugs and/or alcohol. It is believed that if a person performs the field sobriety tests poorly, it is because their coordination has been affected by drugs and/or alcohol they may have consumed. In the United States, there are three field sobriety tests that are approved by the National Highway Traffic and Safety Administration. These tests are the:
- Walk and turn test;
- One leg stand test; and
- Horizontal gaze nystagmus test
In the past, there were other tests that were commonly used by law enforcement, but these tests are no longer encouraged because they are known to be inaccurate in terms of determining if a person is intoxicated or not. Some past field sobriety tests include counting officer's fingers, reciting the alphabet, counting backwards, hand-pat test and standing with feet together and tilting the head backwards. If you have been arrested after a field sobriety test, team up with a Dallas criminal defense lawyer who is familiar with the DWI process.
Challenging Your Arrest: Why You Need a Dallas DWI Attorney
When an officer asks a person to perform the field sobriety tests, chances are that they already believe that the person is under the influence, so it is advisable that the person refuses to do the tests as the officer will decide if the person passes or fails. Additionally, these tests are prone to error because not everyone has the natural agility or coordination it takes to perform these tests to a judgmental officer's satisfaction.
It is a known fact that people have failed field sobriety tests for reasons such as poor police instruction, bad weather, slippery roads and lack of lighting.
