What Constitutes DUI Manslaughter?
Every crime in Florida is composed of elements, and each of these elements must be proven to a jury beyond a reasonable doubt. The definition of the crime of DUI manslaughter can be found here in Fl St 316.193. You may be charged with DUI manslaughter in Florida if all the following elements are present:
- You were driving or in actual physical control of a vehicle in Florida;
- You were under the influence of alcohol, a chemical substance, or a controlled substance that impaired your normal faculties; or
- You had a breath-alcohol or blood-alcohol concentration (BAC) of 0.08% or higher;
- And—most critically—your actions caused or contributed to the death of another person, whether directly or indirectly.
“Actual physical control” means you were in or on the vehicle and had the ability to operate it, regardless of whether it was running at the time.
“Vehicle” means every device in, upon, or by which any person or property is or may be transported or drawn upon a highway[, except personal delivery devices, mobile carriers, and devices used exclusively upon stationary rails or tracks].
“Normal faculties” include but are not limited to the ability to see, hear, walk, talk, judge distances, drive an automobile, make judgments, act in emergencies and, in general, to normally perform the many mental and physical acts of our daily lives.
“Impaired” means diminished in some material respect. Shaw v. State, 783 So. 2d 1097 (Fla. 5th DCA 2001).
Penalties for DUI Manslaughter in Florida
In addition to a maximum of fifteen (15) years imprisonment, this second-degree felony offense also requires a four-year minimum mandatory prison sentence and other penalties including up to a $10,000 fine and a permanent driver’s license revocation. Since DUI manslaughter is a felony, that means it is also subject to sentencing under the CPC (criminal punishment code). Based on the inclusion of death points as well as the points required for the primary offense itself, the DUI manslaughter will always result in a presumptive CPC guideline sentence minimum of over 10 years in prison barring a downward departure sentence. And even if a downward departure reason is proven and the Court can be convinced to downward depart, a downward departure is not applicable to the 4 year minimum mandatory sentence. Hopefully you can see now how incredibly serious DUI manslaughter in Florida can be, and why you need DUI manslaughter attorney Matt Landsman’s help today.
DUI Manslaughter is a second-degree felony, carrying:
- Up to 15 years in prison
- Up to $10,000 in fines
- Mandatory probation, community service, substance abuse treatment, and psychosocial evaluations

This is not a charge to face alone. You need a criminal defense attorney who understands how to challenge every aspect of the prosecution’s case. At Landsman Law, Matt Landsman has litigated every aspect of DUI manslaughter including challenging medical records, search warrants, illegal investigations, interrogations, expert witnesses, traffic reconstruction, and more.
Common Defenses in DUI Manslaughter Cases
DUI manslaughter cases are fact-intensive, and a skilled attorney like DUI manslaughter attorney Matt Landsman can raise several legal and evidentiary defenses. The following list is included to help generally understand the areas of defense, and is not all inclusive of all the many issues and circumstances where expert defense lawyer Matt landsman has fought DUI manslaughter cases:
- Unlawful Traffic Stop: Officers must have reasonable suspicion or probable cause to stop a driver. If the stop was improper, evidence gathered afterward may be inadmissible.
- Improper Field Sobriety Tests: Field tests are subjective and often unreliable—especially if you have a medical condition or disability. Officers must be trained and follow proper protocol.
- Lack of Probable Cause for Arrest: An arrest must be based on solid evidence. If it isn’t, breath or blood test results may be suppressed.
- Faulty Breathalyzer or Blood Tests: These tests must be properly administered and the equipment regularly maintained. Flaws in testing procedures or calibration can invalidate results.
- Causation Disputes: Even if impairment is proven, the prosecution must show that the driver’s actions actually caused or contributed to the fatal accident. If a victim dies from unrelated causes (e.g., a medical emergency after the crash), or the defendant’s driving did not contribute to the accident, the causation element may be successfully challenged.
In-Court Strategies to Fight DUI Manslaughter Charges
Every DUI manslaughter case involves complex evidence—from accident reconstruction to toxicology reports. Matt Landsman takes an aggressive, detail-oriented approach that includes:
✅ Discovery Motions
To compel the state to turn over all evidence—especially anything that may support your innocence.
✅ Motions to Suppress
To challenge illegal searches, unlawful seizures, or violations of your Miranda rights.
✅ Motions in Limine
To block prejudicial or irrelevant information from reaching the jury.
✅ Challenging Scientific Evidence
Field sobriety tests, blood samples, and breath results can all be questioned by attacking testing procedures, human error, and flawed devices.
✅ Causation Defense
The state must prove that your actions—not another driver, not road conditions, not an unrelated health issue—directly caused the death. Without that link, the case fails.
