What Is DUI Manslaughter Under Florida Law?
DUI manslaughter is charged when a person driving under the influence causes, or contributes to causing, the death of another person, including an unborn child (Fla. Stat. § 316.193(3)). The State does not have to prove you intended to hurt anyone, and it does not have to prove you were driving badly at the moment of the crash. It must prove three things: you were driving or in actual physical control of a vehicle; you were impaired or had a BAC of 0.08% or higher; and your operation of the vehicle caused or contributed to a death. That “contributed to” language matters; Florida courts have upheld convictions even where the other driver shared fault for the collision, which is exactly why these cases demand an aggressive causation defense.
Penalties for DUI Manslaughter in Florida
DUI manslaughter is a second-degree felony, punishable by up to 15 years in prison, 15 years of probation, and a $10,000 fine, and Florida law imposes a four-year mandatory minimum prison sentence upon conviction. If the driver knew or should have known the crash occurred and failed to stop and render aid, the charge becomes DUI manslaughter/leaving the scene, a first-degree felony punishable by up to 30 years.
A conviction also brings permanent revocation of your driver’s license, restitution to the victim’s family, and a felony record that follows you for life. Sentencing courts apply Florida’s Criminal Punishment Code scoresheet, where a death raises the score so high that a prison sentence far above the four-year minimum is the starting point, making the fight over the charge itself, not just the sentence, everything.
Defending a DUI Manslaughter Charge
These cases are won or lost on the evidence, and every element can be challenged:
- Causation. Accident reconstruction can show the crash and the death would have occurred regardless of any impairment: the other driver ran the light, a mechanical failure intervened, or road design contributed. If your driving didn’t cause or contribute to the death, DUI manslaughter fails even if impairment is proven.
- The blood draw. In fatal crashes, police typically obtain blood evidence, and the warrant, the draw procedure, the chain of custody, and lab analysis are all attackable. Suppressed blood results can collapse the impairment element.
- The stop, arrest, and statements. Constitutional violations at any stage can exclude key evidence, including statements made at the scene while you were injured or in shock.
- Actual physical control and identity. In multi-occupant and ejection cases, proving who was driving is not a formality.

DUI Manslaughter vs. Vehicular Homicide
The two charges overlap but are not the same. Vehicular homicide (Fla. Stat. § 782.071) punishes killing another through reckless driving, no impairment required. DUI manslaughter punishes causing death while impaired, no recklessness required. Prosecutors sometimes charge both from one crash; a defendant cannot be convicted of both for the same death, and the charging choice significantly changes the defense strategy and sentencing exposure.
