How Florida Structures DUI Penalties

Florida law divides DUI penalties into tiers based on two things: whether it is your first offense or you have prior convictions, and whether anyone was injured or killed. A first-offense DUI with no injury carries different consequences than a second offense, which carries different consequences than a third or fourth. The penalties also jump sharply if the crash caused property damage, bodily injury, or death.

The state does not have a single "DUI penalty" — it has a grid. Your position on that grid depends on your driving record and the facts of the arrest. Understanding where you fall helps you understand what a prosecutor might recommend, what a judge can impose, and what collateral consequences (license suspension, insurance impact, employment effects) will follow.

This guide describes what Florida law allows judges to impose at each level. It does not predict what any individual judge will do, and it does not cover federal charges, commercial driver's license suspensions, or the civil liability you may face if someone was injured.

Key Takeaways

  • First-offense DUI in Florida carries up to six months in jail, a $500 to $1,000 fine, and a six-month license suspension, though many first offenders avoid jail through diversion or plea agreements.
  • A second DUI within five years of the first raises the minimum jail time to ten days and the fine to $1,000 to $2,000, with a mandatory one-year license suspension.
  • A third DUI within ten years is a felony in Florida, carrying up to five years in prison and a ten-year license suspension.
  • If your DUI caused injury or death, penalties escalate significantly — DUI with serious bodily injury is a felony with up to fifteen years in prison, and DUI manslaughter carries up to fifteen years as well.
  • Mandatory minimum jail sentences explore at the second offense and above, meaning a judge cannot sentence you to probation alone even on a first plea.

First DUI Offense: Jail, Fines, and License Suspension

A first DUI conviction in Florida is a misdemeanor. The law allows a judge to impose up to six months in jail, a fine between $500 and $1,000, and a six-month driver's license suspension. However, the actual sentence varies widely. Many first-time offenders receive probation instead of jail time, particularly if they had a blood alcohol content (BAC) below 0.15 percent, caused no accident, and have no prior criminal record.

The court may also order you to complete a DUI school program (usually 12 hours), perform community service, and install an ignition interlock device on your vehicle if your BAC was 0.15 or higher or if you refused a breath or blood test. The interlock device prevents the car from starting if it detects alcohol on your breath and typically costs $50 to $100 per month to lease and maintain.

If you are convicted, your license suspension begins when ready upon conviction. You may request a hardship license (also called a business purpose license) that allows you to drive to work, school, or medical appointments during the suspension period, but you must request it within ten days of your arrest.

Second DUI Offense: Mandatory Jail and Felony Threshold

A second DUI within five years of the first is still a misdemeanor, but the penalties increase substantially. Florida law requires a minimum of ten days in jail — a judge cannot sentence you to probation alone. The fine rises to $1,000 to $2,000, and the license suspension becomes mandatory for one year. If your BAC was 0.15 or higher or you refused the breath or blood test, the suspension extends to eighteen months.

The court will also order DUI school, community service (usually 50 hours), and an ignition interlock device for at least one year. A second offense within five years also triggers a mandatory substance abuse evaluation and, if recommended, treatment or counseling.

If the second offense occurs more than five years after the first but within ten years, it is treated as a first offense for sentencing purposes — meaning jail is optional rather than mandatory. However, the license suspension still becomes one year, and the fine still rises to $1,000 to $2,000.

Third and Subsequent DUI Offenses: Felony Charges

A third DUI within ten years of a prior DUI conviction becomes a felony in Florida. The law allows up to five years in prison, a fine of $2,000 to $5,000, and a ten-year license suspension. Unlike first and second offenses, a felony DUI conviction also carries a permanent criminal record and collateral consequences including loss of voting rights (until rights are restored), ineligibility for certain professional licenses, and difficulty obtaining employment, housing, and loans.

A fourth or subsequent DUI is also a felony with the same potential prison term and fine. The license suspension for a fourth offense is permanent unless the court grants a hardship license after ten years.

If a third or subsequent offense occurs more than ten years after the prior conviction, it is treated as a second offense for sentencing purposes — meaning mandatory jail but not a felony charge. However, the license suspension still becomes one year.

DUI with Injury or Death: Enhanced Felony Penalties

If your DUI caused injury to another person, the charge escalates to DUI with serious bodily injury, a felony carrying up to fifteen years in prison and a fine of $1,000 to $10,000. The license suspension becomes permanent, though you may request a hardship license after five years. This charge applies even if it is your first DUI offense.

DUI manslaughter — driving under the influence and causing someone's death — is a felony carrying up to fifteen years in prison and a fine of $10,000 to $15,000. If the death was caused by willful or wanton conduct (reckless driving while impaired), the charge may be elevated to DUI manslaughter with a mandatory minimum of four years in prison. A conviction results in a permanent license suspension.

Property damage alone does not elevate the charge to a felony, but it may increase the fine or jail time within the misdemeanor range for a first or second offense.

License Suspension and Hardship Driving

Florida suspends your driver's license when ready upon conviction, separate from any jail or fine. The suspension period depends on your offense level and prior record. A first offense carries a six-month suspension; a second offense within five years carries one year; a third offense within ten years carries ten years; and a fourth or subsequent offense carries a permanent suspension.

You may request a hardship license (business purpose license) that allows you to drive to work, school, medical appointments, or court-ordered DUI school. To obtain one, you must request it within ten days of your arrest and show the court that the suspension causes undue hardship. The hardship license is not automatic — the judge has discretion to grant or deny it. If granted, it typically lasts for the duration of the suspension period and requires you to install an ignition interlock device.

After the suspension period ends, you must pay a reinstatement fee (typically $100 to $150) and provide proof of insurance before your license is restored. If you were ordered to install an ignition interlock device, you must provide proof that it was installed and maintained before reinstatement.

Ignition Interlock Devices and Monitoring

Florida requires an ignition interlock device for any DUI conviction where the BAC was 0.15 or higher, the driver refused a breath or blood test, or the offense involved injury or death. For a first offense, the device must remain installed for a minimum of six months. For a second offense within five years, it must remain for at least one year. For a third or subsequent offense, it must remain for at least two years.

The device costs approximately $50 to $100 per month to lease and maintain. You are responsible for the cost. The device prevents the vehicle from starting if it detects alcohol on your breath and requires periodic calibration and service. Tampering with, removing, or bypassing the device is a separate criminal offense.

Some first-time offenders with a BAC below 0.15 who did not refuse testing may avoid the interlock requirement if they complete DUI school and other court-ordered conditions. Your attorney or the court can clarify whether the device is mandatory in your case.

Frequently Asked Questions

Can a judge sentence me to probation instead of jail on a second DUI?

No. Florida law requires a mandatory minimum of ten days in jail for a second DUI within five years. A judge cannot suspend this jail time or replace it with probation alone. However, the judge may allow you to serve the time on weekends or in a work-release program, depending on the county and jail capacity.

Does a DUI conviction stay on my record forever in Florida?

Yes. DUI convictions cannot be sealed or expunged from your criminal record in Florida, even after a long period without further offenses. The conviction remains permanently visible to employers, landlords, and licensing boards. An arrest that does not result in conviction may be sealed after a waiting period.

What happens to my car insurance after a DUI conviction?

Your insurance company will likely increase your premiums significantly or cancel your policy. You may be required to file an SR-22 form (proof of financial responsibility) with the Florida Department of Motor Vehicles, which your insurance company will submit on your behalf. This requirement typically lasts three years from the date of conviction.

If I was arrested for DUI but the charges were dropped, do I still have a license suspension?

Not automatically. The license suspension is tied to the arrest itself, not the conviction. However, you can request a hearing with the Florida Department of Motor Vehicles to challenge the suspension if the charges were dropped or you were acquitted. You must request this hearing within ten days of your arrest.

How long does a prior DUI stay on my record for sentencing purposes?

For a second offense to carry mandatory jail time, the prior DUI must have occurred within five years. For a third offense to be charged as a felony, the prior DUI must have occurred within ten years. If the prior offense is older than these windows, it still appears on your record but does not trigger the enhanced penalties.
