Florida's HB 351 Criminal Speeding Law: What Triggers It and How to Avoid It
)
Florida's HB 351 Dangerous Excessive Speeding Law: What It Means and When Speeding Becomes a Crime
You get pulled over for speeding.
You assume you'll pay a fine, maybe take traffic school, and move on.
But in Florida, some speeding violations are no longer treated as ordinary traffic infractions.
Under Florida's HB 351, certain types of extreme speeding are classified as criminal offenses.
That means jail time, mandatory court appearances, and a criminal case instead of a traditional traffic citation.
The Short Answer
Florida's dangerous excessive speeding law took effect on July 1, 2025.
Under Florida Statute §316.1922, a driver may be charged with dangerous excessive speeding if they:
- Drive 50 mph or more above the posted speed limit, or
- Drive 100 mph or more in a manner that threatens the safety of other people or property or interferes with another vehicle.
A conviction can result in:
- Jail time
- Criminal fines
- Mandatory court appearances
- License consequences for repeat offenses
This isn't an ordinary speeding ticket.
It's a criminal misdemeanor.

Why Florida Passed HB 351
Before HB 351 became law, speeding violations were generally handled through Florida's civil traffic system.
Drivers could often pay a fine, attend traffic school, or resolve the violation without entering the criminal justice system.
HB 351 changed that.
Florida lawmakers created a new offense called dangerous excessive speeding to address situations involving extremely high speeds.
The law created a clear distinction between:
- Traditional speeding violations
- Criminal speeding offenses
Understanding that distinction is important because the legal process, penalties, and potential consequences are very different.
What Speeds Trigger Criminal Charges?
Florida Statute §316.1922 creates two separate situations that can trigger dangerous excessive speeding charges.
Driving 50 MPH or More Above the Speed Limit
This part of the law is straightforward.
Examples:
- 85 mph in a 35 mph zone
- 105 mph in a 55 mph zone
- 120 mph in a 70 mph zone
If you're traveling 50 mph or more above the posted speed limit, you may be charged with dangerous excessive speeding.
Driving 100 MPH or More in a Way That Threatens Public Safety
The second part of the law is different.
The statute doesn't simply say "100 mph."
It says:
100 mph or more in a manner that threatens the safety of other persons or property or interferes with the operation of another vehicle.
This means that the specific facts of the situation may matter.
Road conditions.
Traffic.
Weather.
The presence of other vehicles.
The officer's observations.
The circumstances surrounding the stop can all become important.
Is This a Traffic Ticket or a Criminal Charge?
This is one of the most important things to understand.
Regular speeding violations are traffic infractions.
Dangerous excessive speeding is a criminal offense.
That changes everything.
Instead of simply paying a citation, you may have to appear in criminal court and respond to formal charges.
What Are the Penalties for a First Offense?
Under Florida law, a first conviction for dangerous excessive speeding may result in:
- Up to 30 days in jail
- A fine of up to $500
- A mandatory court appearance
The judge determines the sentence.
Not every case results in jail time.
However, incarceration is a possibility under the statute.
What Happens If You're Convicted Again?
The penalties become more severe.
A second or subsequent conviction may result in:
- Up to 90 days in jail
- A fine of up to $1,000
And if the violation occurs within five years of a prior conviction, Florida law requires license revocation for at least 180 days and up to one year.
Will You Have to Go to Court?
Yes.
Unlike many traditional speeding citations, dangerous excessive speeding cases require a court appearance.
Ignoring the citation isn't an option.
Paying online usually isn't an option.
You should carefully review every document you receive and pay close attention to all court deadlines.
Does This Create a Criminal Record?
A conviction under Florida's dangerous excessive speeding law is a criminal conviction.
Criminal convictions can affect:
- Employment opportunities
- Professional licensing
- Housing applications
- Background checks
The long-term consequences of a criminal conviction can extend far beyond the original traffic stop.
Can You Go to Traffic School?
Don't assume that traffic school is an option.
Dangerous excessive speeding is treated differently than an ordinary speeding citation.
Because these cases involve criminal charges, the options available in a traditional traffic case may not apply.
Can You Fight the Charges?
Yes.
Like other criminal cases, dangerous excessive speeding charges can be challenged.
Potential issues might include:
- How speed was measured
- Whether the officer correctly identified the vehicle
- Whether the evidence supports the alleged speed
- Whether the facts support the allegation that public safety was threatened
Every case is different.
The strength of a defense depends on the specific facts and evidence.
Should You Hire an Attorney?
If you're charged under Florida's dangerous excessive speeding statute, you should seriously consider speaking with a lawyer.
This isn't a routine traffic ticket.
It's a criminal case.
An attorney can explain:
- The charges against you
- The evidence in the case
- Potential defenses
- Whether there are opportunities to negotiate or reduce the charges
What Should You Do After Receiving an HB 351 Citation?
Step 1: Read the Citation Carefully
Identify the statute listed on your citation.
Look for references to Florida Statute §316.1922.
Step 2: Confirm Your Court Date
Court appearances are mandatory.
Missing a required appearance can create additional legal problems.
Step 3: Gather Information
Keep copies of:
- Your citation
- Any court paperwork
- Any documents you receive from law enforcement or the court
Step 4: Consider Speaking With an Attorney
Because this is a criminal matter, legal advice may be particularly important.
Step 5: Understand the Consequences Before Making a Decision
Don't assume this case can be handled the same way you handled a previous speeding ticket.
Criminal charges require a different approach.
