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.

    "I would refer anyone to this firm"
    It always baffled me how much both Jason and Gary knew about the intricacies of my case at any given time. These guys work for, and show up to court for, their CLIENTS - in other words, they're not cutting a bunch of deals to clear dockets. I will never go anywhere else for legal advice - these guys are the real deal.

    "Forever Grateful"
    I have to go into detail here because there’s no way That I cannot give high praise for what Nicole Carlucci did for my daughter and I. I’ve learned the hardest way possible that men tend to be at a great disadvantage when dealing with a divorce and with custody problems. My ex-wife kidnapped our child and had every intention of destroying our bond and the great relationship we have. It’s the saddest thing in the world how some people take their own struggles and personal feelings out by using their children as pawns and manipulating to hurt others. Which is why I could not be happier and more grateful for the day I walked into Porter & Porter Law Firm. From day one, my story was heard, understood, and through a year and a half of what felt like full on war just so I could maintain my relationship with me daughter without us being ripped from each other’s lives, Nicole Carlucci supported me and used her expertise to get as close to the absolute best result possible. She never gave up or gave in and that helped me to stay strong, too, when there would be days or weeks my daughter and I would not see each other. If not for Nicole, I can only imagine how much more awful such a nightmare of a situation could have gotten. However, I am now divorced, continue to have an amazing relationship with my daughter, and have court orders to hold my ex responsible and accountable so that way certain things will hopefully never happen again, and if they do, I know who I am calling!! Nicole’s passion to help someone being taking advantage of and her drive to ensure justice be served when someone is manipulating the system is exactly what my daughter and I needed so we can live a happy life. Thank you Nicole and Firm!!

    "Jason and his staff were very professional."
    100% success rate. I used Jason Porter's services two different times for a DUI charge. The first DUI case I never lost my license and he won the case. The second time it was a little more difficult because of the circumstances but we took it to trial and it seemed like an effortless victory. Jason and his staff were very professional and helpful through the entire process.I could not have asked for anything more. Thank you so much for everything.
