How DUI Evidence Is Challenged in Florida Courts
A DUI arrest can feel like the case is already decided the moment handcuffs come out. But an arrest is not a conviction, and the evidence prosecutors rely on to prove impairment is often far less solid than it appears. Florida courts allow defense attorneys to scrutinize every piece of evidence collected during a stop, and that scrutiny frequently reveals problems that can weaken or even sink the state’s case.
Was the Traffic Stop Actually Lawful?
Every DUI case begins with a stop, and every stop must be supported by reasonable suspicion. If an officer pulled a driver over without a legitimate reason, such as a traffic infraction or credible tip, then everything that followed the stop may be subject to challenge. Courts have suppressed evidence in cases where the initial justification for the stop does not hold up under review.
Field Sobriety Exercises Are Not as Objective as They Seem
Field sobriety tests are designed to measure balance, coordination, and the ability to follow instructions, but a wide range of factors unrelated to alcohol can affect performance. Uneven pavement, poor lighting, nervousness, fatigue, footwear, and underlying medical conditions can all cause someone to fail a test despite being completely sober. An attorney can examine how the tests were administered and whether the officer followed standardized procedures.
Breath Test Results Depend on More Than the Machine
Breath testing in Florida is governed by strict protocols. Under Florida Statute 316.1932, a breath test must be requested incident to a lawful arrest by an officer with reasonable cause to believe the driver was impaired. Beyond the legal requirements, the machines themselves must be properly calibrated and maintained, and the officer administering the test must follow observation periods and procedural steps precisely. Any deviation, from a skipped waiting period to an improperly certified device, can call the results into question.
Officer Observations Can Be Contradicted by Other Evidence
Much of a DUI case rests on an officer’s written report and personal observations. Dash camera and body camera footage, when available, often tells a different story than the report. Video can show a driver speaking clearly, walking steadily, or otherwise behaving in ways that contradict claims of impairment. Comparing the footage against the report is one of the most effective ways to identify inconsistencies.
Building a Strategy Around Weak Evidence
Every DUI case is built on a chain of evidence, and a weakness at any link, whether it is the stop, the testing procedure, or the officer’s account, can create meaningful doubt. A thorough review of dashcam footage, calibration records, and arrest documentation often uncovers issues that were not obvious at first glance.
