Facing a DUI manslaughter charge is one of the most devastating experiences a person can endure — legal or otherwise. The weight of a tragic accident, the grief of a victim’s family, the attention of law enforcement and prosecutors, and the very real prospect of decades in prison, all descending at once. If you or someone you love is confronting this situation in Broward County, you need to understand what Florida law now demands, and why retaining an experienced Fort Lauderdale criminal defense lawyer immediately may be the single most consequential decision you make.
What Trenton’s Law Does to the Sentencing Landscape
Under Florida Statute § 316.193(3)(c)(3), DUI manslaughter has long been classified as a second-degree felony, carrying a maximum of 15 years in prison and a fine of up to $10,000. A mandatory minimum of four years in state prison applies. The Florida Criminal Punishment Code scoresheet, which accounts for victim injury points, typically pushes the recommended sentence for a first-time offender to well over ten years before a judge has said a single word.
That was already a severe framework. Then came Trenton’s Law.
House Bill 687, signed by Governor Ron DeSantis and effective October 1, 2025, was named for Trenton Stewart, an 18-year-old Stetson University freshman killed in Jacksonville by a wrong-way driver who already carried a prior DUI manslaughter conviction out of Broward County. The legislation fundamentally reshapes the consequences for repeat impaired driving offenders. Under HB 687, any person with a prior conviction for DUI manslaughter, BUI manslaughter, vehicular homicide, or vessel homicide who is subsequently charged with one of those same offenses now faces a first-degree felony — with a maximum sentence of 30 years in Florida state prison. There is no look-back period. A DUI conviction from twenty years ago is as qualifying as one from last year.
The law also elevates the offense ranking on Florida’s Criminal Punishment Code severity chart: DUI manslaughter with a prior qualifying conviction is now ranked at Level 9. That’s the same tier as armed robbery and aggravated battery with great bodily harm. The sentencing implications of that reclassification are severe and immediate.
For prosecutors in Broward County, the message from Tallahassee is clear: pursue these cases aggressively, and the law will support you at every step.
The Fear of a 30-Year Sentence Is Real — But So Is the Defense
If you are reading this because someone you care about is under investigation or has been charged, the fear you are feeling is entirely understandable. But fear, however justified, should not paralyze you. What matters most in the first hours and days after an arrest is not how the charge is labeled — it is how quickly and effectively a defense attorney gets to work.
Here is the foundational legal reality the prosecution will never advertise: even under Trenton’s Law’s enhanced framework, the State must still prove every element of DUI manslaughter beyond a reasonable doubt. That means proving the defendant was operating the vehicle, that they were impaired or had a BAC of 0.08% or higher, and — critically — that their impaired operation caused or contributed to the death of another person. So while the State is not required to prove that the defendant’s drinking alone caused the accident, causation must still be established. A defendant cannot be convicted of DUI manslaughter simply because their vehicle was “involved in” an accident. The operation of the vehicle must have caused or contributed to the fatal outcome. That is a meaningful legal threshold, and one that a skilled defense attorney can challenge. Continue reading
