What Is Trenton’s Law?

On October 1, 2025, a sweeping new Florida law known as Trenton’s Law took effect, fundamentally changing how DUI and BUI offenses are prosecuted and punished in Florida. This legislation represents one of the most significant expansions of DUI penalties in recent Florida history.

Specifically, Trenton’s Law accomplishes four major objectives: it criminalizes refusal to submit to chemical testing, enhances penalties for repeat offenders, increases sentencing for DUI and BUI manslaughter, and updates Florida’s Criminal Punishment Code to impose higher sentencing points for impaired driving offenses. Consequently, anyone arrested for DUI or BUI after October 1, 2025 faces substantially more severe consequences than under prior law.

Breath Test Refusal Is Now a Crime

One of the most significant changes under Trenton’s Law is the criminalization of breath and urine test refusal. Prior to October 1, 2025, refusing a lawful request for chemical testing resulted in an administrative license suspension but was not itself a criminal offense.

Under the new law, refusing to submit to testing now carries the following criminal penalties:

Moreover, officers must now clearly advise drivers that refusing a lawful test is not only grounds for license suspension but also a crime that can be prosecuted. This expanded implied consent warning ensures defendants cannot claim ignorance of the criminal consequences.

Enhanced DUI and BUI Manslaughter Penalties

Trenton’s Law dramatically increases penalties for DUI manslaughter, BUI manslaughter, vehicular homicide, and vessel homicide—particularly for defendants with prior convictions. Under the new law, these offenses are now elevated to first-degree felonies when the defendant has a prior conviction for any of these offenses.

Prior Convictions That Trigger Enhancement

A defendant’s current charge will be elevated to a first-degree felony if they have any prior conviction for:

• DUI manslaughter (Florida Statute § 316.193(3)(c)3)
• BUI manslaughter (Florida Statute § 327.35(3)(c)3)
• Vehicular homicide (Florida Statute § 782.071)
• Vessel homicide (Florida Statute § 782.072)

Trenton’s Law: Before and After Comparison

Offense Severity Ranking Changes

Trenton’s Law also updates Florida’s Offense Severity Ranking Chart under the Criminal Punishment Code. DUI, BUI, vehicular homicide, and vessel homicide offenses have been moved higher on the chart, resulting in significantly more sentencing points.

In Florida’s sentencing system, higher offense severity rankings translate directly into longer mandatory minimum sentences and increased prison exposure. Therefore, even defendants without prior convictions will face harsher guideline sentences for DUI and BUI offenses committed after October 1, 2025.

Boating Under the Influence (BUI) Enhancements

Trenton’s Law applies identical enhancements to boating under the influence offenses. For Tampa Bay area boaters—including those in Hillsborough, Pinellas, and Pasco counties—this means that BUI arrests now carry the same serious consequences as DUI arrests.

Specifically, the law provides that:

• Refusing breath or urine testing during a BUI investigation is now a criminal offense
• BUI manslaughter with a prior conviction for DUI manslaughter, BUI manslaughter, vehicular homicide, or vessel homicide is a first-degree felony
• Vessel homicide carries enhanced sentencing points under the Criminal Punishment Code

What Trenton’s Law Means for Tampa Bay Drivers and Boaters

For drivers and boaters across Tampa Bay—including Hillsborough, Pinellas, and Pasco counties—Trenton’s Law significantly raises the stakes in DUI and BUI cases. The changes affect everyone from first-time offenders to those with prior records.

A refusal to blow is no longer just an administrative suspension—it can now lead to a permanent criminal record. Likewise, repeat DUI or BUI offenders face life-altering felony enhancements that can result in decades of prison time.

If you or a loved one is charged under this new law, it is crucial to work with an experienced defense attorney who understands both the criminal trial process and the nuances of Florida’s sentencing guidelines.

Frequently Asked Questions: Trenton’s Law

What is Trenton’s Law in Florida?

Trenton’s Law is a 2025 Florida statute that significantly increases penalties for DUI and BUI offenses. The law criminalizes breath test refusal, enhances penalties for repeat offenders, elevates DUI and BUI manslaughter to first-degree felonies for defendants with prior convictions, and increases sentencing points under Florida’s Criminal Punishment Code. It takes effect October 1, 2025.

Does refusing a breath test now carry criminal charges in Florida?

Yes. Under Trenton’s Law, refusing to submit to a lawful breath or urine test is now a criminal offense. A first refusal is a second-degree misdemeanor punishable by up to 60 days in jail and a $500 fine. A second or subsequent refusal is a first-degree misdemeanor punishable by up to one year in jail and a $1,000 fine.

What happens if someone with a prior DUI manslaughter conviction causes another fatal crash?

Under Trenton’s Law, they can now be charged with a first-degree felony, which carries a maximum penalty of 30 years in state prison. This is a dramatic increase from the previous second-degree felony classification, which carried a maximum of 15 years.

Does Trenton’s Law apply to boating under the influence (BUI)?

Yes. The law applies identical enhancements to BUI offenses. Refusing testing during a BUI investigation is now a criminal offense, and BUI manslaughter with a prior conviction is now a first-degree felony. Vessel homicide also receives enhanced sentencing points.

When does Trenton’s Law take effect?

Trenton’s Law takes effect on October 1, 2025. All DUI and BUI arrests occurring on or after this date will be subject to the new enhanced penalties, including criminal charges for refusal.

Should I refuse the breath test under the new law?

This is a complex legal question that depends on your specific circumstances. Under Trenton’s Law, refusal now carries criminal penalties in addition to license suspension—but providing a breath sample can also provide evidence for the prosecution. An experienced DUI attorney can help you understand the strategic considerations based on your individual situation.

What prior convictions trigger the first-degree felony enhancement?

The first-degree felony enhancement applies if the defendant has any prior conviction for DUI manslaughter, BUI manslaughter, vehicular homicide, or vessel homicide. Any one of these prior convictions will elevate a new DUI manslaughter, BUI manslaughter, vehicular homicide, or vessel homicide charge to a first-degree felony.

How can a Tampa DUI attorney help with charges under Trenton’s Law?

An experienced Tampa DUI attorney can challenge the legality of the traffic stop, question the administration of field sobriety tests, challenge breath test results, file motions to suppress evidence, negotiate with prosecutors for reduced charges, and advocate for alternative sentencing. Given the enhanced penalties under Trenton’s Law, aggressive defense from the earliest stages is critical.

Why Breath Test Machine Maintenance Matters

When police arrest someone for DUI in Florida, prosecutors typically rely on the Intoxilyzer 8000 to prove impairment. Indeed, this breath testing machine serves as the gold standard for measuring blood alcohol content. However, its results depend entirely on the maintenance and calibration procedures that keep it accurate.

If technicians fail to properly maintain the Intoxilyzer, courts can exclude its results from evidence. As a result, this exclusion can mean the difference between a conviction and a dismissal.

The Case: State v. Kilburn, Marano, and Depauw

In this consolidated appeal, three DUI defendants challenged their breath test results on identical grounds: specifically, the Intoxilyzer 8000 used to test them had undergone an unauthorized repair.

The critical fact proved simple: FDLE inspectors replaced the breath tube on the Intoxilyzer 8000. However, under Florida’s rules, only the manufacturer or an approved repair facility may perform such repairs. Because the repair violated Florida’s administrative rules, the court concluded that technicians had not properly maintained the machine. Therefore, the presumption of accuracy that normally applies to breath test results disappeared.

Common Grounds to Challenge Intoxilyzer Results

The Kilburn case focused on unauthorized repairs. However, defense attorneys can challenge Intoxilyzer 8000 results on many other grounds in Florida DUI cases:

How an Experienced DUI Attorney Investigates Breath Test Evidence

At The Brancato Law Firm, P.A., we examine every detail of DUI cases. Specifically, we investigate the complete maintenance and inspection history of the Intoxilyzer 8000 used to test you. Furthermore, this investigation includes:

• First, requesting all maintenance logs and repair records for the specific machine
• Second, reviewing FDLE inspection reports for compliance with Florida Administrative Code
• Third, verifying the breath test operator held valid certification at the time of testing
• Additionally, examining video evidence to confirm officers followed the 20-minute observation period
• Moreover, identifying any unauthorized repairs or gaps in the maintenance chain
• Finally, deposing FDLE inspectors and breath test operators when necessary

As a result, this detailed investigation frequently reveals issues that provide grounds to suppress breath test evidence—just as the defense attorneys accomplished in Kilburn.

Frequently Asked Questions: Intoxilyzer Maintenance and DUI Defense

Can courts throw out breath test results if technicians failed to properly maintain the Intoxilyzer?

Yes. As the Kilburn case demonstrates, Florida courts will exclude Intoxilyzer 8000 results if the State cannot prove technicians maintained the machine according to Florida Administrative Code requirements. Specifically, this includes proper inspections, authorized repairs, and calibration procedures.

What qualifies as an “unauthorized repair” on an Intoxilyzer 8000?

Under Florida law, only the manufacturer or an approved repair facility may perform repairs on the Intoxilyzer 8000. In Kilburn, for example, FDLE inspectors replaced the breath tube themselves—a repair they lacked authorization to perform. Because this violated Florida’s rules, the court excluded the breath test results.

How often must FDLE inspect the Intoxilyzer 8000 in Florida?

Florida Administrative Code Rule 11D-8 requires FDLE to inspect the Intoxilyzer 8000 at least once per calendar month. Therefore, if gaps exist in the inspection records—or if officers used the machine during a period when FDLE missed inspections—this can provide grounds to challenge the results.

What is the 20-minute observation period?

Before administering a breath test, officers must observe the subject for at least 20 minutes. During this time, they must ensure the subject does not eat, drink, smoke, vomit, or put anything in their mouth. Essentially, this prevents mouth alcohol contamination from affecting the results. Consequently, failure to properly conduct this observation can provide grounds to challenge the test.

Can I request the maintenance records for the Intoxilyzer used in my case?

Yes. Your defense attorney can subpoena all maintenance logs, repair records, and inspection reports for the specific Intoxilyzer 8000 that officers used to test you. Indeed, these records prove essential for identifying potential grounds to challenge the breath test results.

What happens if the court excludes breath test results in my DUI case?

Without breath test results, prosecutors must rely on other evidence—such as field sobriety tests, officer observations, and video footage. As a result, this often leaves them with a significantly weaker case. Depending on the remaining evidence, the State may reduce charges or dismiss them entirely.

Does the officer’s certification affect breath test validity?

Yes. The breath test operator must hold valid certification at the time of testing. Therefore, if the officer’s certification had expired or the officer obtained it improperly, this can provide grounds to challenge the breath test results.

Should I refuse a breath test in Florida?

Refusing a breath test in Florida carries significant consequences. Specifically, implied consent laws trigger automatic license suspension and a separate charge apart from the DUI. However, every case presents different circumstances. If police have already arrested you for DUI—whether you took the test or refused—contact an experienced DUI defense attorney immediately to discuss your options.
