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.

    "Jason Porter is superb."
    This is my personal experience with Jason porter. I was in need of an attorney. I didn't have a clue on where to go...who to call . or even if they would take the time to listen to my case. Jason porter was extra observative Very calm .. cool.. and collective. Very laid back . But don't let that fool ya. He's a very good attorney. He took our case and since the 1st visit he has lived up to everything he said he could do. Since every case is different. I truly feel as if he took our case personal This is so rare to see in attorneys nowdays Having a attorney that puts aside the so called business mentality to put people first is what I received even tho our case was small I'm sure there will be someone with a need for a attorney and I'm not some rich guy . I live paycheck to paycheck every week but I was treated like royalty respect . And I felt like my case was important I will never forget what he done with my case and the personal decision he made at the end that showed me beyond a doupt that Jason porter is a attorney on our side . Fighting for the clients not a paycheck . not afraid to stand up n fight and never break a sweat his cool demeanor breaks it all down so it's very understanding ... I can't tell you who to call for your attorney but if u read this. then u need to stick with Jason . I'm sure you'll love him and I'm sure you'll be happy Thanx again Jason porter you won my vote for attorney of the year 2015 and I hope I can help someone with there decision on choosing an attorney With Jason's law firm you won't go wrong

    "He is our family attorney forever."
    There are times when you may need unforeseen legal assistance and your scared and don't have a clue if youre making the right choice. The decision is not an easy one when it's based on your family and life. You worry if they have your best interest at heart, if they know enough, if they know the right people and it's very emotional & confusing. Ten years ago my family was faced with the worst nightmare any mother could ever imagine & I prayed to God to make the right decision and I did. Meeting Jason Porter & his assistant Darlene C. (she's been with him longer than that), was the best in my life in my family's life. Jason doesn't have a big office turn around, in fact I have watched his office grow to the success it is today. His staff stays because they know they are with a terrific guy & great attorney. I can go on and on and mean every word from the bottom of my heart but the are truly no words to describe the great outcomes he has had for 2 of my sons on separate occasions. Unfortunately, we don't live in a society anymore where "boys will be boys". There are way too many laws and not enough of societal morality (due to a change of the times). Boys may get in trouble, they did get in trouble but with their unfortunate choices, my choice was the better in retaining Jason and his law firm. He is our family attorney forever.

    "Throughout the whole process, he was responsive and dedicated and he made it seem like I was the only case he was dealing with."
    I recently worked with Jonathan Thacher and am very pleased with the outcome of the case. Throughout the whole process, he was responsive and dedicated and he made it seem like I was the only case he was dealing with. He was on top of getting the necessary measure taken and the end result was outstanding. I would definitely refer anyone to him! Thank you so much, Jonathan!!

    "Thankful to this firm for their hard work and dedication!"

    I unfortunately experienced a terrible accident and was hurt. I reached out to Jason Porter’s law firm, as he has helped my father in the past and is a trusted attorney in my family.

    Unfortunately, the process had a slow start due to many moving pieces. Hildy stepped in and things got moving IMMEDIATELY! She is amazing. So sweet, so understanding, so educated and intelligent regarding her position. Because of her, I felt assured and heard.

    Thankful to this firm for their hard work and dedication!

    "Mr. Porter and his staff are fantastic."
    Mr. Porter and his staff are fantastic. They clearly explained the charges, potential outcomes and estimated timelines. They worked closely with me to tailor their services to my unique situation. The entire team demonstrated extensive knowledge of the law, flexibility, and responsiveness. These qualities helped put my mind at ease until they were able to get all charges against me dropped. I would highly recommend this law firm.
