Understanding Florida DUI Laws, Dismissal Grounds, and Defenses That Can Protect Your Future
A DUI arrest in Florida can feel like the weight of the world has landed on your shoulders. The possibility of losing your license, facing steep fines, or even serving jail time is enough to cause anyone sleepless nights. But not every DUI arrest results in a conviction, and under certain circumstances, charges can be dismissed entirely. As Florida DUI defense attorneys, we have seen firsthand how cases can collapse when the law has not been followed precisely. Whether the police made errors during the stop, mishandled breath or blood test evidence, or violated your constitutional rights, the opportunity for dismissal may exist. The key is knowing how Florida's DUI laws work, where the weaknesses might be in the prosecution's case, and having the right legal team to expose them.
Florida's DUI Law: Key Statutes That Matter in Dismissal Cases
The starting point in any DUI dismissal analysis is Florida Statute §316.193, which defines the offense:
§316.193(1), Florida Statutes:
"A person is guilty of the offense of driving under the influence and is subject to punishment as provided in subsection (2) if the person is driving or in actual physical control of a vehicle within this state and:
(a) The person is under the influence of alcoholic beverages, any chemical substance set forth in s. 877.111, or any substance controlled under chapter 893, when affected to the extent that the person's normal faculties are impaired; or
(b) The person has a blood-alcohol level of 0.08 or more grams of alcohol per 100 milliliters of blood; or
(c) The person has a breath-alcohol level of 0.08 or more grams of alcohol per 210 liters of breath."
This statute lays the groundwork for how the State must prove a DUI. The burden rests entirely on the prosecution to establish every element beyond a reasonable doubt. If even one link in that chain is missing or defective, dismissal becomes a possibility.
Grounds for Dismissal in Florida DUI Cases
1. Lack of Reasonable Suspicion for the Stop
Under the Fourth Amendment and Florida law, an officer must have a specific and articulable reason to initiate a traffic stop. This could be a traffic infraction or observable impairment. If there was no valid reason, any evidence gathered may be suppressed.
Why a private attorney matters: Proving an unlawful stop often requires filing and arguing a Motion to Suppress, which demands legal skill and courtroom experience. Without it, critical evidence stays in play.
2. Absence of Probable Cause for Arrest
Florida law requires that an arrest be supported by probable cause, meaning the officer had sufficient facts to believe you were driving under the influence. Weak field sobriety test performance, for example, is not enough if the tests were administered incorrectly or under unfair conditions.
Why a private attorney matters: We have successfully argued that certain arrests lacked probable cause because officers relied on flawed roadside observations. Once probable cause fails, the entire case can unravel.
3. Breath or Blood Test Errors
Florida Statute §316.1932 governs implied consent for chemical testing. But these tests are only admissible if conducted according to strict administrative rules. This includes calibration logs, machine maintenance, and the 20-minute observation period before testing.
§316.1932(1)(a)1.a., Florida Statutes:
"The chemical or physical breath test must be incidental to a lawful arrest and administered substantially in accordance with methods approved by the Department of Law Enforcement."
Why a private attorney matters: Without reviewing maintenance logs, officer certifications, and the observation timeline, these issues may never be discovered.
4. Violation of Constitutional Rights
This includes failure to read Miranda warnings after arrest if interrogation occurs, unlawful searches, or denial of the right to counsel.
Why a private attorney matters: Constitutional violations can lead to suppression of statements or evidence, often resulting in dismissal when the State's proof collapses.
Common Defenses That Lead to Dismissal
- Rising Blood Alcohol Defense – Your BAC may have been below the legal limit while driving, only rising above 0.08 later.
- Medical Conditions Mimicking Impairment – Inner ear issues, neurological disorders, or fatigue can mimic signs of impairment.
- Unreliable Field Sobriety Tests – Florida courts recognize that these are subjective and prone to officer error.
- Improper Checkpoint Procedures – DUI checkpoints must follow strict guidelines; failure can void arrests.
Why a private attorney matters: The prosecution will not volunteer weaknesses in their own case. Identifying and proving these defenses takes thorough investigation and skill.
Why Prosecutors Sometimes Dismiss DUI Charges
Even when evidence exists, prosecutors may dismiss if key witnesses are unavailable, evidence is suppressed, or the cost of the trial outweighs the likelihood of conviction. In some cases, a negotiated resolution can also lead to dismissal after completion of diversion programs.
How We Build a Case for Dismissal
Our approach always starts with obtaining every piece of discovery: dashcam footage, bodycam recordings, 911 calls, breath machine records, and officer notes. We file targeted motions to exclude evidence obtained in violation of your rights. We cross-examine officers on every detail of their procedures. We also consult toxicologists when BAC accuracy is in doubt.
Real Case Example
One of our clients was stopped late at night for "weaving." The dashcam video revealed he was merely avoiding potholes. The officer claimed slurred speech and unsteady balance, but the bodycam footage showed the client speaking clearly and walking normally. The breath test registered 0.09, but the machine's maintenance logs showed it had failed calibration two days earlier. We filed a Motion to Suppress the breath test and argued the stop lacked reasonable suspicion. The judge agreed, suppressing the breath result and ruling the stop unlawful. Without evidence, the State dismissed the case before trial.
Why You Need a Private DUI Attorney
Public defenders are skilled lawyers, but they carry overwhelming caseloads and may not have the time to comb through every record or conduct independent investigations. A private defense attorney can focus entirely on your case, pursue every angle for dismissal, and provide personal guidance through every step of the process.

Florida DUI Dismissal FAQs
Can my DUI be dismissed if the officer never told me why I was stopped?
Yes, if the stop was made without reasonable suspicion of a traffic violation or criminal activity, the evidence collected afterward can be suppressed. Without that evidence, prosecutors may have no case. We have won dismissals in such situations by showing dashcam video that contradicted the officer's claims.
What if the breathalyzer was not working properly?
Florida law requires breathalyzers to be properly maintained and calibrated according to strict Department of Law Enforcement rules. If records show the machine was out of compliance, your test result may be inadmissible. This can leave the State with no reliable BAC evidence, leading to dismissal.
Do medical conditions matter in a DUI case?
Absolutely. Conditions like diabetes, hypoglycemia, or certain neurological disorders can cause symptoms mistaken for intoxication. These conditions can also affect breath test results, such as by producing acetone in the breath. With medical records and expert testimony, we can show that the officer's observations were misleading.
Can DUI checkpoint arrests be thrown out?
Yes. Florida requires law enforcement to follow strict written guidelines for DUI checkpoints. If they fail to adhere to these procedures, all resulting arrests can be invalidated. We have successfully challenged DUI checkpoint arrests by exposing procedural violations.
Does refusing a breath test help my case?
Refusal can result in license suspension under Florida's implied consent law, but it can also deprive prosecutors of a key piece of evidence. In some cases, we have still achieved dismissals for clients who refused, particularly when the stop or arrest was unlawful.
Can I get a dismissal if I passed the field sobriety tests?
Passing or performing reasonably on these tests can undermine the State's claim of impairment. If the rest of the evidence is weak or tainted, the prosecutor may decide not to proceed. We use video evidence to show jurors exactly how well our clients performed.
What if the officer didn't read me my rights?
Miranda warnings are required before custodial interrogation. If the officer questioned you after arrest without giving these warnings, your statements may be suppressed. While this alone may not dismiss the case, it can weaken the prosecution's evidence significantly.
Is dismissal possible if I had a BAC over the limit?
Yes. A high BAC alone does not guarantee a conviction. If the stop was unlawful, the arrest lacked probable cause, or the test was flawed, the results can be excluded from evidence. Once suppressed, the State may have no way to prove impairment.
How long does it take to get a DUI dismissed?
It varies. Some dismissals happen early, even before formal charges are filed, while others occur after months of litigation. The sooner you hire a private defense attorney, the sooner they can begin identifying dismissal opportunities.
