People who are pulled over for the suspicion of drunk driving are often asked to take a series of tests to determine whether they’re impaired or not. Some of these tests require the person to perform specific tasks so the officer can observe how they handle them. These are known as field sobriety tests.
While there are many different field sobriety tests, there are only three that are considered reliable enough to be used in a criminal case. These are part of the standardized field sobriety test (SFST). The SFST is the only option that’s endorsed by the National Highway Traffic Safety Administration.
What are the components of the SFST?
The three components of the SFST include:
- Walk and turn: Walk nine heel-to-toe steps, turn around, and return to the starting point
- Horizontal gaze nystagmus: Follow an object with only the eyes while the officer observes the eyes’ reaction
- One-leg stand: Stand with one foot off the ground approximately six inches for 30 seconds
Together, all three of these tests can provide the officer with a reliable way to gauge a person’s ability to drive. However, the SFST isn’t foolproof, which is one important point that may come up in a defense strategy against drunk driving charges. In some cases, lack of proper training or improper interpretation of the results can skew the results.
It’s critical that anyone who’s facing these charges understands what options they have for a defense strategy. Working with someone familiar with these matters may be beneficial for these individuals.
