I’m Rocky Brancato, founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm. I am a member of the National College for DUI Defense, I taught at the police academy, and I have taken more than 150 jury trials to verdict — and DUI manslaughter is the case our attorneys treat as the most defensible serious charge in Florida, because it is built entirely on scientific evidence that can be tested, challenged, and suppressed.

How Does Florida Define DUI Manslaughter?

DUI manslaughter has three parts under section 316.193(3), Florida Statutes: the driver was under the influence (impaired normal faculties, or a blood- or breath-alcohol level of .08 or above); the driver operated a vehicle; and, by reason of that operation, the driver caused or contributed to causing the death of a human being or an unborn child.

Notice what is missing: intent. No one charged with DUI manslaughter meant to hurt anyone, and the law does not require that they did. Notice also what is not missing: causation.

The “contributes to” language means the State can convict even when the other driver shares fault — but it cannot convict on impairment alone. If the crash would have happened exactly the same way with a sober driver behind your wheel — the other car ran the red light, the pedestrian stepped out from between parked cars, the motorcycle crossed the center line — the death was not caused by reason of your operation, and our attorneys have built entire defenses on that distinction.

What Are the Penalties for DUI Manslaughter in Florida?

The 4-year mandatory minimum means exactly what it says: no matter how sympathetic the facts, a judge cannot go below four years in prison on a DUI manslaughter conviction. And the sentencing scoresheet usually demands far more — the death itself adds victim-injury points that typically put the lowest permissible sentence above ten years before a single aggravator is considered. That gap between the 4-year floor and the scoresheet’s number is one of the most important battlegrounds in these cases.

Beyond prison, a DUI manslaughter conviction carries permanent revocation of your driver license under section 322.28 — the court must impose it, and if the court doesn’t, the DHSMV will. The one door the Legislature left open: under section 322.271(4), a driver with no prior DUI-related convictions may petition for hardship reinstatement five years after the revocation or the end of incarceration, whichever is later — after proving five drug-free years, no unlicensed driving, and completion of DUI school, with an employment-restricted license for the first year.

How Does Sentencing Actually Work in a DUI Manslaughter Case?

Three different numbers control a DUI manslaughter sentence, and understanding the space between them is where defense work pays off:

The scoresheet is where many families are blindsided: they hear “4-year minimum” and expect a number near it, then learn the Criminal Punishment Code calculation demands more than a decade. But the scoresheet is not untouchable. Florida law recognizes grounds for a downward departure — and in these cases, the mitigation is often real: a defendant with no record, genuine remorse, cooperation, and a crash in which the victim’s own conduct played a role. Our attorneys build the sentencing case in parallel with the trial defense, because in a charge with a mandatory minimum, the plea negotiations are conducted in the shadow of both numbers.

A conviction also brings the DUI-specific consequences that follow any conviction under section 316.193 — among them mandatory probation conditions including a licensed DUI program and substance abuse treatment, community service, and vehicle impoundment rules — layered on top of the prison term and the permanent license revocation discussed above.

What Must the State Prove to Convict You?

Three elements, each beyond a reasonable doubt:

1. Impairment or unlawful alcohol level. Proven through the blood or breath test, officer observations, field sobriety exercises, and video. Every link in that chain — the stop, the draw, the lab, the analyst — is contestable.
2. Operation of a vehicle. Usually undisputed, but not always: in multi-occupant crashes and ejection cases, who was driving becomes the entire trial.
3. Causation. By reason of that operation, the driver caused or contributed to causing the death. This is where accident reconstruction lives — speed, angles, timing, right-of-way, and what the other vehicle was doing.

Can You Fight the Blood Test in a DUI Manslaughter Case?

September 2026 update: Yes — and the ground shifted on September 2, 2026. In State v. Marlin, No. 4D2025-1448 (Fla. 4th DCA Sept. 2, 2026), the Fourth District affirmed suppression of a forced blood draw in a fatal Turnpike crash, held that the natural dissipation of alcohol is never a per se exigency, and receded from the “probable cause” language in State v. Acevedo that prosecutors had been treating as an exception to the warrant requirement. Absent actual consent or case-specific exigent circumstances, a warrant is required — regardless of Florida’s implied consent law. Our full analysis is in can police take your blood without a warrant in Florida.

Yes — and in our firm’s experience the blood evidence is where DUI manslaughter cases most often crack. Florida’s appellate courts spent 2025 reminding trial judges how narrow the State’s authority to take blood really is. In State v. Marshall, No. 4D2024-1115 (Fla. 4th DCA Aug. 13, 2025), a driver’s blood was drawn twice at an accident scene, and the case turned on whether the draw was lawful — the appellate court sent it back because the trial court’s findings on consent and implied consent contradicted each other.

Marshall collects the rules that matter. A mandatory blood draw under section 316.1933 requires probable cause of two things at the roadside — that the driver was impaired and that the driver’s vehicle caused death or serious bodily injury. Implied consent applies only to blood taken based on probable cause of a qualifying DUI offense. And when the State claims the driver voluntarily consented, the State carries the burden of proving voluntariness under the totality of the circumstances — mere submission to authority is not consent.

The practical translation: in a case where everything flows from a number in a vial, the defense examines how that vial was filled. Was there probable cause of causation at the moment of the draw, or just a hunch? Was “consent” given by a person in shock, in handcuffs, or in an ambulance? Was the kit expired, the draw non-medical, the chain of custody clean? Our attorneys litigate these motions in Hillsborough County courtrooms, and a suppressed blood result changes everything that follows.

How Do We Defend DUI Manslaughter Charges?

By attacking each element with its own expert. On causation, we retain accident reconstruction experts to analyze the physics of the crash — because “impaired driver” plus “someone died” does not equal “the impairment caused the death,” and juries understand that distinction when it is shown to them with data. On impairment, we litigate the stop, the draw, and the lab: suppression of the blood result, rising-alcohol timelines, and the difference between the level at testing and the level at driving. On operation, where the facts allow it, we hold the State to its proof of who was behind the wheel. And on sentencing, we fight the scoresheet — victim-injury points, downward departure grounds, and the space between the statutory minimum and the State’s demand.

One more thing our attorneys do from day one: preserve the evidence that helps you. Vehicles get crushed, event data recorders get overwritten, and surveillance video gets deleted on retention schedules measured in days. A preservation demand in the first week is often worth more than any motion filed a year later.

What Is the Difference Between DUI Manslaughter and Vehicular Homicide?

They are alternative theories for the same tragedy, with different elements. DUI manslaughter requires impairment but not bad driving — a legally intoxicated driver who causes a fatal crash can be convicted even if the driving itself was unremarkable. Vehicular homicide (§ 782.071) requires reckless driving but no impairment. Prosecutors often charge both from one crash; a defendant cannot be convicted of both for the same death, and the interplay between the two counts is itself a defense opportunity — each theory concedes the weakness of the other.

What Should You Do If You Are Under Investigation for DUI Manslaughter?

Retain counsel immediately — before the charging decision, not after. DUI manslaughter charges are often filed weeks or months after the crash, while the traffic homicide investigator waits for toxicology and reconstructs the scene. That window is when the defense can still inspect the vehicles, download the event data recorders, photograph the roadway, and demand preservation of every recording. It is also when statements do the most damage: what you tell the traffic homicide investigator — even a polite explanation at the hospital — becomes evidence. Our attorneys step in during the investigation, handle all law-enforcement contact, and put our own experts on the physical evidence before it disappears.

Frequently Asked Questions About DUI Manslaughter in Florida

What is the mandatory minimum sentence for DUI manslaughter in Florida?

Four years in prison — a judge cannot sentence below it on a conviction, no matter the circumstances. The realistic exposure is higher: the maximum is 15 years (30 for the first-degree versions), and the sentencing scoresheet’s victim-injury points usually put the lowest permissible sentence well above the 4-year floor. Our attorneys fight both numbers — the conviction itself and the scoresheet math.

Can DUI manslaughter charges be reduced or dismissed?

Yes, when an element fails. A suppressed blood test can gut the impairment element; reconstruction evidence can break causation; and either can drive a reduction to DUI, reckless driving, or another lesser offense. The Brancato Law Firm, P.A. builds these cases around independent expert work from the first week, because that is when the evidence that wins them still exists.

Will I lose my license permanently?

A DUI manslaughter conviction requires permanent revocation — but permanent does not always mean forever. If you have no prior DUI-related convictions, section 322.271(4) lets you petition for hardship reinstatement five years after the revocation or your release from prison, whichever is later, after DUI school and five clean years. Our attorneys plan for that petition as part of the case, not as an afterthought.

What if the other driver caused the crash?

Then causation — an element the State must prove beyond a reasonable doubt — is in play. The statute’s “causes or contributes to causing” language tolerates shared fault, but it still requires that your operation contributed to the death; if the crash would have happened the same way with a sober driver in your seat, that element fails. This is precisely what accident reconstruction experts are for, and it is the first thing our firm evaluates.

Can the police take my blood without my consent?

Only within narrow limits. A mandatory draw under section 316.1933 requires probable cause at the scene that you were impaired and that your vehicle caused death or serious bodily injury; anything less requires a warrant or genuinely voluntary consent, which the State must prove — submission to an officer’s authority is not consent. As the Fourth District’s 2025 decision in State v. Marshall shows, courts scrutinize these draws closely, and a bad draw means a suppression motion.

Does Trenton’s Law apply to DUI manslaughter?

Yes. A DUI manslaughter conviction is a first-degree felony — a 30-year maximum — if you have a prior conviction for DUI manslaughter, BUI manslaughter, vehicular homicide, or vessel homicide. Whether a prior actually qualifies is a legal question worth litigating, and The Brancato Law Firm, P.A. scrutinizes every alleged qualifying prior.

I’m Tampa criminal defense attorney Rocky Brancato. As a member of the National College for DUI Defense (NCDD) and the DUI Defense Lawyers Association, and as a former police academy instructor who taught officers how to conduct criminal investigations, I bring a unique perspective to every Florida DUI charges case — I know how officers are trained and where their procedures fall short.

How Does Florida Define DUI?

Under §316.193, you can face DUI charges in Florida if you are driving or in “actual physical control” of a vehicle and one of three conditions is met: your normal faculties are impaired by alcohol or drugs, your blood-alcohol level is 0.08 or higher, or your breath-alcohol level is 0.08 or higher.

Florida Statute §316.193: The phrase “actual physical control” is critical. You do not have to be driving to be charged with DUI — sitting in the driver’s seat with the keys accessible can be enough. The State must prove you were either impaired to the extent your normal faculties were affected, or that your BAC was at or above 0.08. At The Brancato Law Firm, P.A., we challenge both the impairment evidence and the chemical test results.

“Normal faculties” under Florida law include your ability to see, hear, walk, talk, judge distances, make judgments, act in emergencies, and drive a vehicle. The State typically relies on field sobriety exercises, the officer’s observations, and chemical test results to prove impairment. Each of these has weaknesses we can exploit.

What Are the Penalties for DUI in Florida?

Florida DUI charges carry penalties that increase sharply with each offense and with certain aggravating factors:

In addition to the criminal penalties outlined above, DUI charges in Florida trigger license suspension, increased insurance rates, and a permanent criminal record. The Brancato Law Firm, P.A. fights to prevent these consequences at every stage.

What Happens If You Refuse the Breathalyzer?

Florida’s implied consent law means that by driving on Florida roads, you have already consented to chemical testing if an officer has lawful cause to believe you are impaired. If you refuse, DHSMV automatically suspends your license — 1 year for a first refusal, 18 months for a second.

However, the consequences of refusal changed dramatically on October 1, 2025. Under Trenton’s Law (HB 687), a first-time refusal to submit to a breath or urine test is now a separate second-degree misdemeanor — carrying up to 60 days in jail and 6 months of probation — charged independently from the DUI itself. A second or subsequent refusal remains a first-degree misdemeanor punishable by up to 1 year in jail and a $1,000 fine. Furthermore, officers must now advise you that refusal can lead to criminal prosecution in addition to the administrative license suspension. Because the refusal charge is filed separately, you can be convicted of refusing the test even if the DUI charge is dismissed.

That said, refusing the breathalyzer does not mean the State wins on Florida DUI charges. In fact, many DUI cases without chemical test results are more defensible because the State must rely entirely on the officer’s observations and field sobriety exercises. At The Brancato Law Firm, P.A., we have won DUI cases where our clients refused testing — and we also defend the separate refusal charge aggressively.

Case Study — Not Guilty, DUI and Resisting Officer: We represented a client charged with DUI (refusal) and resisting arrest without violence. Using scene video, Rocky argued the client was not impaired and contended the officer was overly aggressive. The jury returned a verdict of Not Guilty on both counts. Past results do not guarantee future outcomes.

When Does DUI Become a Felony in Florida?

Warning: A third DUI within 10 years of a prior conviction is a third-degree felony carrying up to 5 years in prison. A fourth or subsequent DUI is always a felony — regardless of how much time has passed between offenses. DUI causing serious bodily injury is a third-degree felony, and DUI manslaughter is a second-degree felony punishable by up to 15 years. If you left the scene of a DUI crash that caused death, the charge becomes a first-degree felony with up to 30 years.

The jump from misdemeanor to felony DUI changes everything — prison instead of jail, a permanent felony record, and the loss of civil rights. If you are facing a felony DUI charge, the stakes could not be higher. At The Brancato Law Firm, P.A., we have the trial experience to fight these charges aggressively.

How We Fight DUI Charges in Tampa

Because I taught criminal procedure at the police academy, I know exactly how officers are trained to conduct DUI investigations — and I know where those procedures break down. Here is how we fight DUI charges in Florida at The Brancato Law Firm, P.A.:

• Challenge the traffic stop. If the officer had no lawful reason to stop you, everything that followed — including the breath test — may be suppressed.
• Challenge field sobriety exercises. These exercises are subjective and unreliable. Medical conditions, uneven surfaces, footwear, and nervousness all affect performance. We demonstrate that poor performance does not equal impairment.
• Challenge the breath or blood test. The operator must properly calibrate and maintain breathalyzer machines. The operator must follow specific procedures. If the operator skipped any step, the court may exclude the result.
• Challenge “actual physical control.” If you were sleeping in a parked car, sitting in the passenger seat, or not actually driving, we argue you were not in actual physical control of the vehicle.
• Use the video. Dash camera and body camera footage often tells a different story than the officer’s report. We review every second of available video.

Can DUI Charges Be Dropped or Reduced in Florida?

Yes — and prosecutors reduce Florida DUI charges more often than most people realize. The most common outcome we pursue is a reduction to reckless driving, which avoids a DUI conviction on your record. Here are the paths we take at The Brancato Law Firm, P.A.:

• Reckless driving reduction. If weaknesses exist in the State’s evidence, we negotiate a reduction to reckless driving — no DUI on your record, no mandatory license suspension, and significantly lower insurance impact.
• Motion to suppress. If the stop, the detention, or the chemical test violated your constitutional rights, we file a motion to suppress. If the evidence is thrown out, the case often collapses.
• DHSMV hearing challenges. DHSMV handles your license suspension separately from the criminal case. We fight the administrative suspension to keep you driving while the criminal case is pending.

Case Study — Marijuana DUI Reduced to Reckless Driving: We represented a client charged with DUI (marijuana) — the blunt was lit at the time of the stop and thick smoke was visible on video. Despite this evidence, Rocky negotiated a reduction to reckless driving, keeping the DUI conviction off our client’s record. Past results do not guarantee future outcomes.

Case Study — DUI Reduced to Reckless Driving: Officers stopped our client with open liquor bottles in the vehicle and admitted to consuming alcohol. However, Rocky demonstrated the client was not unlawfully impaired. Result: Reduced to reckless driving. Past results do not guarantee future outcomes.

What Should You Do After a DUI Arrest?

If you are facing DUI charges in Florida and have been booked at Orient Road Jail or Falkenburg Road Jail, take these steps immediately:

1. Request a DHSMV hearing within 10 days. After a DUI arrest, you have only 10 calendar days to request a formal review hearing with DHSMV to fight your license suspension. If you miss this deadline, the suspension takes effect automatically.
2. Call a DUI defense attorney before your first appearance. Your arraignment at the Hillsborough County Courthouse happens quickly. An attorney can argue for favorable bond conditions and begin building the defense.
3. Do not discuss the case. Do not post about the arrest on social media, do not discuss it with friends, and do not speak with law enforcement without an attorney present.
4. Preserve evidence. Dash camera footage, body camera video, and surveillance recordings can all support the defense — but they do not last forever.

Case Study — DUI License Suspension Overturned, CDL Reinstated: Our client lost both a standard driver’s license and a commercial driver’s license (CDL) after a DUI arrest. Rocky handled the DHSMV hearing personally and filed a petition for writ of certiorari in circuit court. The judge ruled the suspension improper and reinstated both licenses. Past results do not guarantee future outcomes.

Frequently Asked Questions About DUI in Florida

Is a first DUI a felony in Florida?

No — a first DUI is a misdemeanor carrying up to 6 months in jail. However, if the DUI caused serious bodily injury, it becomes a third-degree felony. If it caused a death, it becomes DUI manslaughter — a second-degree felony. The Brancato Law Firm, P.A. defends clients facing DUI charges at every level in Hillsborough, Pinellas, and Pasco Counties.

Can I lose my license for a DUI in Florida?

Yes. A first DUI conviction results in a 180-day to 1-year license suspension. A second conviction within 5 years results in a 5-year suspension. A third conviction results in a 10-year suspension. In addition, refusing the breathalyzer triggers an automatic administrative suspension. Tampa criminal defense attorney Rocky Brancato fights both the criminal charge and the license suspension simultaneously.

What is the BAC limit in Florida?

The legal limit is 0.08 for standard drivers and 0.02 for drivers under 21. A BAC of 0.15 or higher triggers enhanced penalties, including higher fines and longer potential jail time. However, a BAC reading is not always accurate — machine calibration issues, operator errors, and medical conditions can all produce false results.

More Questions About DUI Defense

Can DUI charges be dismissed in Florida?

Yes. If the officer conducted an unlawful traffic stop, improperly administered the breath test, or failed to follow required procedures, the court may suppress the evidence — and without evidence, the case is often dismissed. The Brancato Law Firm, P.A. examines every step of the investigation for constitutional violations.

Should I take the breathalyzer or refuse?

Since October 1, 2025, Trenton’s Law makes this decision even more consequential. A refusal now triggers both an automatic license suspension and a separate criminal charge — a second-degree misdemeanor for a first refusal, a first-degree misdemeanor for a second. However, submitting to the test gives the State direct evidence of your blood-alcohol level. There is no one-size-fits-all answer — the best strategy depends on the specific circumstances. If you have already been arrested, contact The Brancato Law Firm, P.A. immediately to discuss your options.
