Field Sobriety Tests Serving Families Throughout Jacksonville For Over 25 Years

Field Sobriety Tests Defense in Jacksonville

Powerful Defense from Our Dedicated Legal Team

If a police officer suspects you are driving under the influence, the officer will ask you to perform field sobriety tests. While the officer will not tell you this, these tests, unlike the breath test, are voluntary and rarely to your advantage to agree to take them as they are fundamentally physical agility tests and can be failed by even a sober person. Nevertheless, if you fail, the officer will use them to defend the decision to arrest you for DUI.

Standardized Field Sobriety Tests

For those who have been arrested following field sobriety tests, there is good news. By working with an experienced Jacksonville DUI lawyer well-versed in these tests, you may be able to invalidate the results in court. Usually prosecutors use breath, blood or urine test results to establish that a defendant is DUI. However, sometimes these test results are not usable in court due to procedural errors. At that point, the prosecutor will fall back on field sobriety tests to prove that you are DUI. The most common tests are:

  • Horizontal Gaze Nystagmus (HGN): The officer positions an object twelve inches away from your eyes and moves it back and forth. The officer observes your eyeballs to see if they lurch or quiver.
  • Walk and Turn (WAT): You are asked to take nine heal-to-toe steps along a line and then turn around and walk back. The officer watches to see if you lose balance or make mistakes.
  • One Leg Stand (OLS): While standing straight with arms at your side, you are asked to raise one leg six inches and start counting until the officer tells you to stop. The officer watches for you raising your arms to balance yourself or any other non-optimum action.

    "The Best I Could Imagine!!!"
    I used Jason Porters services after a bad roll over accident involving myself and my ALMOST 1 year old daughter when I lived in Jacksonville. Within 24 hours of contacting the office, I was seen by 2 physicians and my case was in full motion. My husband was deployed, and I was scared at first. However, Mr. Porter and his ENTIRE staff had me at immediate ease. I could email or call his assistant at any hour with any concern, and would have a response very quickly. I would highly recommend this office to anyone at any time. The compassion of the entire staff was more than I could have expected.

    "I will never be able to thank Jason Porter enough."
    Jason Porter has helped me on two separate occasions and both times his attention to detail really impressed me. His staff is wonderful and easy to work with. The second time I worked with Jason Porter, he turned what I thought was a hopeless situation into a miracle. He literally got me my life back by getting the charges reduced. His experience as a trial lawyer came in handy when he had to work with the district attorney to change the judge's mind on my case. Jason Porter has a calming demeanor and he instilled confidence when going over the details of my case. I tended to be pessimistic, but Jason Porter would always reassure me and keep me positive. I will never be able to thank Jason Porter enough for all that he has done for me and my family. I hope I never need a lawyer again, but if I do I know I can count on Jason Porter to give me my best chance at a favorable outcome.
