Florida Drunk Driving Laws: Penalties, License Loss, and Costs

A first-offense DUI in Florida is a misdemeanor punishable by a fine of $500 to $1,000 and up to six months in jail, and Florida DUI penalties climb sharply from there: mandatory jail on a second offense within five years, a third-degree felony for a third offense within ten years, and permanent license revocation after a fourth conviction or a DUI manslaughter.¹ On top of the criminal sentence, a conviction brings mandatory DUI school, community service, vehicle impoundment, an ignition interlock device in many cases, three years of high-limit FR-44 insurance, and potential problems entering Canada.

First Offense

A standard first DUI with no aggravating factors is a second-degree misdemeanor. The court can impose a fine of $500 to $1,000, up to six months in jail, and probation of up to one year.¹

Three additional requirements are standard conditions of probation and apply to essentially every first conviction:

Completion of DUI school, which includes a substance abuse education course and a psychosocial evaluation. If the evaluation recommends treatment, you must complete it.²
A minimum of 50 hours of community service.²
Impoundment or immobilization of the vehicle you were driving, or another vehicle in your name, for 10 days.²

DUI school isn’t optional in a practical sense either: you can’t qualify for a hardship license until you finish the course and evaluation.

When a First Offense Gets Worse

Two facts turn an ordinary first DUI into an enhanced one: a BAC of 0.15 or higher, or a minor under 18 in the vehicle. In either case the fine range doubles to $1,000 to $2,000, the maximum jail sentence stretches to nine months, and the court must order an ignition interlock device on every vehicle you own or regularly drive for at least six continuous months.² The interlock requires you to pass a breath test before the engine will start.

Second Offense

A second DUI conviction is punishable by a fine of $1,000 to $2,000, up to nine months in jail, and a mandatory ignition interlock device for at least one year.¹

If the second offense falls within five years of the first, the court must impose at least 10 days in jail, with at least 48 hours served consecutively, and the vehicle impoundment extends to 30 days. If BAC was 0.15 or higher, the fine climbs to $2,000 to $4,000, the maximum jail sentence rises to 12 months, and the interlock requirement doubles to at least two continuous years.²

Third Offense

Here the 10-year window is everything. A third DUI within 10 years of a prior conviction is a third-degree felony punishable by up to five years in state prison, with a mandatory minimum of 30 days in jail (48 hours consecutive) and at least a two-year interlock.¹

A third DUI more than 10 years after the prior conviction is treated as a misdemeanor: a fine of $2,000 to $5,000, up to 12 months in jail, and a mandatory two-year interlock.² A common misconception is that any third DUI is automatically a felony. The 10-year clock is what controls it.

Fourth or Subsequent Offense

A fourth DUI is always a third-degree felony, regardless of how many years have passed. The maximum sentence is five years in prison and the minimum fine is $2,000.¹ A fourth conviction also triggers permanent license revocation.

DUI Causing Injury or Death

If someone else is hurt or killed, the charge escalates independently of how many prior DUIs you have. A first-time DUI driver can face a felony on these facts alone.

DUI causing serious bodily injury is a third-degree felony with up to five years in prison. DUI causing property damage or non-serious injury is a first-degree misdemeanor.²

DUI manslaughter is a second-degree felony with a mandatory minimum prison sentence of four years. The judge has no discretion to go below that floor. If the driver knew or should have known the crash occurred and left without rendering aid, the charge is elevated to a first-degree felony.² DUI manslaughter also carries permanent license revocation.

License Suspension and Revocation

Two separate things happen to your driver’s license, on two different timelines.

The first is administrative, handled by the Department of Highway Safety and Motor Vehicles (DHSMV), and it begins at arrest. If you took the test and registered 0.08 or higher on a first offense, the administrative suspension is six months. A first test refusal triggers a 12-month suspension. A second or subsequent refusal is 18 months and is itself a misdemeanor crime.³⁴ You have 10 days from the date of arrest to request a formal review hearing to contest the suspension.

The second is revocation, imposed after a criminal conviction. The DHSMV revocation periods:

First offense, no bodily injury: minimum 180 days, maximum one year.
First offense with bodily injury: minimum three years.
Second offense within five years: minimum five years; hardship reinstatement possible after one year.
Third offense within 10 years: minimum 10 years; hardship reinstatement possible after two years.
Fourth conviction: permanent; hardship reinstatement possible after five years.
DUI manslaughter: permanent.

If a second or third offense falls outside the five- or ten-year window, the revocation generally resets to the first-offense range.³

Getting a Hardship License

Florida offers two kinds of restricted driving privileges during a revocation. A business purposes only license covers work driving plus education, church, and medical trips. An employment purposes only license is narrower, covering just the commute and required on-the-job driving.⁵

You can’t apply for either one until you’ve completed DUI school and the evaluation. With two or more DUI convictions or two or more test-refusal suspensions, the rules tighten: for revocations of five years or less you may petition after 12 months; for longer revocations you must wait at least 24 months, prove you haven’t driven or used drugs for 12 months, and submit to ongoing supervision by a licensed DUI program for the full revocation period.⁵

FR-44 Insurance for Three Years

After a DUI conviction you must file an FR-44 certificate of financial responsibility and carry auto liability coverage at levels well above Florida’s normal minimums: $100,000 for bodily injury or death of one person, $300,000 for bodily injury or death of two or more people in one crash, and $50,000 for property damage. The requirement runs for three years.⁶

The three-year clock starts when your driving privileges are reinstated, not on the conviction date. If coverage lapses, your insurer must notify the DHSMV, which can suspend your license again and restart the FR-44 period. After three clean years, the requirement ends.⁶

If You Hold a Commercial Driver’s License

A CDL carries federal consequences on top of Florida’s. A first DUI disqualifies you from operating a commercial vehicle for one year, or three years if you were hauling hazardous materials at the time. A second DUI-related conviction in a separate incident is a lifetime disqualification from commercial driving.⁷ These federal disqualifications apply even when the DUI happened in your personal vehicle.

Travel to Canada

Canada treats impaired driving as a serious crime, and a single Florida DUI misdemeanor can make you inadmissible at the border. Canadian officers have access to U.S. criminal databases and can turn you away at airports and land crossings.⁸

You can apply for individual rehabilitation once at least five years have passed since you completed the entire sentence, including probation and fines. You may qualify as deemed rehabilitated after a longer period if the offense carries less than a 10-year maximum sentence in Canada. For urgent travel before you’re eligible for either, a Temporary Resident Permit allows entry with a valid reason for the trip.⁸

What a Florida DUI Actually Costs

The fine is usually the smallest line item. Private defense attorneys for a first-offense DUI typically charge between $1,500 and $7,500. FR-44 insurance will raise your premiums substantially for at least three years, with many drivers seeing rates climb anywhere from 50 percent to several hundred percent above pre-DUI levels. Add DUI school, the substance abuse evaluation and any treatment it recommends, interlock installation and monthly monitoring where applicable, towing and impoundment fees, and court costs, and total out-of-pocket costs on a first conviction frequently run into five figures.

None of it is tax-deductible. Federal tax law prohibits deducting fines or penalties paid to a government for violating a law, so the court-imposed costs provide no tax benefit.
