Do Field Sobriety Tests Accurately Measure Your Level Of Impairment?

Nestled in Contra Costa County, California, Pinole is a vibrant city home to approximately 20,000 residents. The name “Pinole” stems from a Native American term for a type of flour crafted from maize and other grains. From its modest beginnings, Pinole has blossomed into a lively community, aided by the establishment of California Powder Works in nearby Hercules and the growth of the Southern Pacific Railroad.

If you’re a Pinole resident, you might find yourself enjoying an evening at local hotspots like Bar None on Tara Hills Drive, where you can unwind with a game of pool, sing karaoke on Saturdays, catch a thrilling ball game, and have a refreshing drink. Alternatively, you may frequent Chuck’s Corner at 610 San Pablo Avenue, known for its laid-back vibe, live music, and exceptional mixed drinks.

After an enjoyable night out, the last thing you expect is to be pulled over and possibly arrested for DUI. If your route took you through Appian Way or Mann Drive, you may have encountered a DUI checkpoint, or a police officer may have stopped you due to your driving behavior.

The Questionable Accuracy of Field Sobriety Tests

If you did participate in field sobriety tests, it’s imperative that you communicate every detail you can remember to your Pinole DUI attorney. A wealth of research indicates that field sobriety tests are notoriously unreliable when determining impairment. Way back in the late 1970s, the Southern California Research Institute was commissioned by the NHTSA to assess the accuracy of various field sobriety tests. Officers observed individuals take these tests and were then asked to identify those with a BAC of .10 percent or higher. Shockingly, the resulting error rate among the officers was a staggering 47 percent.

This means that officers on the scene might as well have flipped a coin instead of using the field tests to gauge impairment.

In nearly half of instances, officers inaccurately determined impairment. Even though the walk and turn, the one-leg stand, and the horizontal gaze nystagmus were deemed the most reliable field sobriety tests, the accuracy rates still fell short: the horizontal gaze nystagmus tested at only 77 percent accuracy, the walk and turn at 68 percent, and the one-leg stand just 65 percent. Compounding this issue is the fact that government guidelines and procedures for administering these tests have changed so frequently over the past 40 years, research indicates that as many as 95 percent of DUI arrests are conducted by officers using outdated training on these tests.

The Importance of Legal Representation After DUI Charges

There are several factors that could render field sobriety tests invalid: the police officer might give instructions incorrectly, the individual taking the tests may possess health conditions affecting their performance, or adverse conditions like poor lighting and inclement weather may hinder their ability to correctly execute the tests. Additionally, the subjective nature of the officer’s scoring can almost guarantee that a test subject will fail, regardless of their true level of impairment. Given the questionable reliability of field sobriety tests, if you face DUI charges predicated on these assessments, rest assured that your attorney can effectively challenge the validity of these scores.

If you have been charged with a DUI in Pinole, California, especially if field sobriety tests were administered as part of your case, it is imperative to consult with a skilled Pinole DUI attorney as soon as possible.
