    Standard Field Sobriety Exercises in South Florida DUI Cases

    Standard Field Sobriety Exercises, or SFSE for short, are a series of tasks administered by law enforcement officers during a DUI investigation. They are often inaccurately referred to as “tests”. The word “exercises” is much more accurate in describing them as these tasks require physical skill and dexterity to complete.

    • SFSE’s are not administered to establish a suspect’s innocence
    • SFSE’s are administered to establish “probable cause” for an arrest
    • SFSE’s do not create evidence of “guilt beyond a reasonable doubt”

    List of Field Sobriety Exercises Used by Law Enforcement During a DUI Investigation:

    • Horizontal Gaze Nystagmus (HGN)
    • Walk-and-Turn
    • One-Leg-Stand
    • Finger-to-Nose (not officially recognized by NHTSA)
    • Rhomberg Balance (not officially recognized by NHTSA)

    What is Being Evaluated During Field Sobriety Exercises on DUI Cases?

    The police are ultimately trying to determine whether or not you are impaired during a DUI investigation. The purpose of the field sobriety exercises is to evaluate whether or not your normal faculties are impaired.

    Normal Faculties Evaluated in a DUI Investigation:

    • Speech
    • Balance
    • Mental state
    • Ability to act in emergencies
    • Ability to make judgments

    The Intoxilyzer 8000 (Also Known as the Breathalyzer or “Breath Test”)

    The breathalyzer is used to determine an individual’s blood alcohol content. Breath tests are often not administered while a suspect is pulled over the side of the road during DUI investigations in South Florida. They are often administered when the suspect is taken to jail. This is often problematic as the breath test may not accurately reflect the blood alcohol level of the individual at the time of the incident.

    Facts on the Intoxilyzer 8000

    • The breathalyzer machine was first manufactured in 2001 and has been in use in Florida since 2006
    • The breathalyzer machine is older than the original smartphones
    • The breathalyzer runs on the outdated Windows VISTA operating system
    • The breathalyzer uses outdated infrared radiation technology

    Blood and Urine Samples in a DUI Investigation

    Urine Samples:

    Urine samples are considered unreliable when used to evaluate drug use at the time of the incident. A urine sample can determine if an individual has used a controlled substance but cannot determine when the individual used the substance nor how much of the substance was used.

    Blood Samples:

    Blood samples are only used during the following cases:

      In one of the most stressful times in my life, Rossen Law Firm was there for me. Leaving no stone unturned they provided patience and knowledge in every detail of my case. I’m very thankful and proud of this law firm family and especially of my lawyer, Scott Simmons for guiding, defending and helping me in every way possible. He and this law firm family come highly recommended from personal experience!!!

      I had an unfortunate situation with a family member that lead to my arrest and being charged with DV Battery. This was the first time I had ever been arrested so I was very nervous and afraid of what was going to happen to me. After talking with Adam I decided to retain him and let me tell you this was the BEST decision I could have ever made. Adam made me feel so comfortable and confident that everything will turn out the best in my favor. He is professional, ethical and supportive. He was always available too answer any questions or concerns.Not to mention, his team at the office is awesome they are so friendly and welcoming. Anytime I had a question when I called the office they were able to guide me in the rightdirection. They always were in contact with me with any information or updates regarding my case. Adams team is GREAT!Adam delivered, my case was DISMISSED. So if you want an attorney the is gonna fight for you and get the job done retain the BEST there is Adam Rossen!!!

      Adam Rossen and the team at Rossen Law took great care in handling my case. They are very professional, and get the job done. I was particular relieved to see just how much empathy they showed with me, and how effortless it was to be their client.I literally visited them twice. My initial consultation, and then to pickup the final docs. I have nothing but great things to say about these folks, and I would highly recommend them to anyone. Thanks Guys.

      I had an amazing experience with The Rossen Law Firm. The staff were very professional. Attorney Susan Lawson went above and beyond working on my case. We were thoroughly prepared for trial. Mrs. Lawson reviewed hours of body and dash camera footage multiple times and aggressively performed depositions on witnesses and law enforcement.The final outcome for me was the state dropped my case, due to the great work Susan and the Rossen team performed. I didn’t even need to go to trial.This law firm does not play around. They pay attention to detail and they FIGHT FOR YOU!Thank you Adam, team, and a special thank you to Susan for your amazing work! I really appreciate you.

      My experience with Rossen Law Firm was excellent. From the consultation to the end.. My attorney Susan Lawson gave my son's case all the time and attention that was needed to be successful in court. She was confident during all the court proceedings. My favorite part was when she said we are family, never once my son and I were treated other then that. I very much appreciate the knowledge and support I received through Rossen Law Firm.
