Field Sobriety Tests: An Overview

Riverside DUI Defense Lawyers

Field sobriety tests are roadside agility exercises which law enforcement officers administer to determine if a motorist is driving under the influence. Although the interpretation of the test results is highly subjective, courts accept the results as evidence of DUI. Fortunately, these tests are not an exact science, and a skilled and experienced attorney from our team can refute the results and seek to have the evidence thrown out.

Common Tests

Horizontal Gaze Nystagmus: The officer holds a pen or other object 15 inches from your eyes and moves the object back and forth while watching your eyeballs. If the eyeballs jerk or tremble involuntary, it is considered to be an indicator of intoxication.

Walk and Turn: You are asked to take nine heel to toe steps along a line and then turn and take nine steps back. The officer looks to see if you can keep your balance and follow directions.

One Leg Stand: While holding your arms to the side and heels together, you are asked to lift one foot off the ground 6 inches while counting. The officer is looking to see how you maintain your balance.

What factors negatively impact field sobriety tests?

In many cases, the results of the tests can be challenged, as there are a number of elements that can affect the test and make the results inaccurate. Some of these things include:

  • The driver’s footwear
  • The driver’s physical health or age
  • Pre-existing medical conditions
  • Nervousness
  • Uneven ground
  • Poor weather or lighting
  • Distractions and noise from the road or highway
  • Unclear instructions from the officer
  • Difficulty understanding the English language

If your results were affected by similar factors, do not hesitate to retain powerful defense to fight your charges. You should not suffer the penalties and stress of DUI allegations based on faulty results. Our team is prepared to challenge the charges and move to the evidence thrown out and your case dismissed.
