Florida Drunk Driving Laws, Penalties, and Consequences

Florida DUI penalties start at $500 to $1,000 in fines, up to six months in jail, and an immediate license suspension for a first offense, and they escalate quickly from there: a third DUI within ten years is a felony, a fourth is always a felony, and any DUI involving injury or death is charged as a felony regardless of your record. On top of the criminal sentence, a conviction triggers DUI school, community service, vehicle impoundment, higher insurance requirements, and, for many drivers, an ignition interlock device.

What Florida Counts as a DUI

Florida law gives prosecutors two ways to prove a DUI, and they only need one. The first is impairment: you were driving or in actual physical control of a vehicle while your normal faculties were impaired by alcohol, a chemical substance, or a controlled substance. “Normal faculties” covers things like seeing, walking, judging distances, and reacting in an emergency.¹

The second path requires no proof of impairment at all. A breath test at 0.08 grams of alcohol per 210 liters of breath, or a blood test at 0.08 per 100 milliliters, is a “per se” DUI no matter how well you were functioning.² For drivers under 21, the limit drops to 0.02, which one drink can produce.³

What Happens to Your License at Arrest

Your license is at risk before you ever see a courtroom. The Department of Highway Safety and Motor Vehicles (DHSMV) starts an administrative suspension at the moment of arrest, separate from the criminal case. Two things trigger it: a breath or blood result at 0.08 or higher, or refusing the test.

A first-time test result at or above 0.08 draws a six-month administrative suspension.⁴ Refusing is worse. Florida’s implied consent law treats driving on state roads as consent to breath, blood, or urine testing when lawfully arrested for DUI. A first refusal is a 12-month suspension. A second or later refusal is 18 months and a separate misdemeanor crime.⁵

You have 10 days from the arrest date to request a formal review hearing with the DHSMV. Miss the deadline and you lose the right to challenge the suspension.

First-Offense Penalties

A standard first DUI with no aggravating factors is a misdemeanor. The fine runs $500 to $1,000, the jail cap is six months, and the court can place you on probation for up to one year.²

Two facts push a first DUI into a harsher tier: a BAC of 0.15 or higher, or a minor under 18 in the vehicle. In either case, the fine doubles to $1,000 to $2,000, jail extends to nine months, and the court must order an ignition interlock device (IID) on every vehicle you own or regularly operate for at least six continuous months.⁶ An IID is a breathalyzer wired to your ignition; the car will not start without a clean sample.

What You Must Do After a First Conviction

Probation conditions come with a checklist that has to be completed:

DUI school: a substance abuse education course through a licensed program, including a psychosocial evaluation. If the evaluation recommends treatment, you complete that too.⁶
At least 50 hours of community service.⁶
Impoundment or immobilization of the vehicle you were driving, or another one registered to you, for 10 days.⁶

DUI school also gates your license. You can’t apply for a hardship license until the education course and evaluation are done.

Second, Third, and Fourth Offenses

Repeat penalties depend on how many prior convictions you have and how long ago they happened. The time between offenses can change the entire classification of your case.

Second Offense

A second DUI carries $1,000 to $2,000 in fines, up to nine months in jail, and a mandatory IID for at least one year. If it happens within five years of the first, the court must impose at least 10 days in jail, with a minimum of 48 hours served consecutively, and impoundment stretches to 30 days for every vehicle you own.⁶

A BAC of 0.15 or higher pushes the fine to $2,000 to $4,000, extends jail to 12 months, and doubles the IID period to at least two continuous years.⁶

Third Offense

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 (at least 48 hours consecutive) and an IID for at least two years.²

If more than 10 years have passed since the last conviction, the third offense stays a misdemeanor: $2,000 to $5,000 in fines, up to 12 months in jail, and a two-year IID.⁶ The 10-year window is what triggers the felony, not the count alone.

Fourth Offense

A fourth DUI is always a third-degree felony, no matter how much time has passed. The maximum is five years in prison, and the minimum fine is $2,000.² The license is permanently revoked.

When a DUI Involves Injury or Death

If someone else is hurt, the charges jump regardless of your prior record. A first-time DUI driver can be charged with a felony.

DUI causing serious bodily injury is a third-degree felony carrying up to five years in prison. DUI causing property damage or non-serious injury is a first-degree misdemeanor.⁶

DUI manslaughter is a second-degree felony with a mandatory minimum of four years in prison, and the judge has no discretion to go lower. If the driver knew or should have known a crash occurred and left without rendering aid, the charge becomes a first-degree felony.⁶

How Long You Lose Your License

The administrative suspension at arrest is one thing. Post-conviction revocation is a separate, longer penalty imposed by the DHSMV:

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

When a second or third offense falls outside the five- or ten-year window, revocation generally resets to first-offense levels.⁴

Florida offers two restricted licenses during a revocation. A “business purposes only” license covers work driving plus trips for education, church, and medical care. An “employment purposes only” license covers just your commute and required work driving.⁷ Neither is available until DUI school and the evaluation are complete.

Insurance, CDL, and Travel Consequences

A DUI conviction requires you to file an FR-44 certificate and carry higher liability limits for three years: $100,000 per person for bodily injury or death, $300,000 per crash for two or more people, and $50,000 for property damage. The three-year clock starts when your driving privilege is reinstated, not on the conviction date. Let the policy lapse and your insurer must notify the DHSMV, which can suspend your license again and restart the filing period.⁸

If you hold a commercial driver’s license, federal rules stack on top of state penalties. A first DUI disqualifies you from operating a commercial motor vehicle for one year, or three years if you were carrying hazardous materials. A second DUI-related conviction from a separate incident is a lifetime commercial driving disqualification.⁹ These federal disqualifications apply even when the DUI happened in a personal vehicle.

Travel to Canada is a common surprise. Canadian immigration law treats impaired driving as a serious crime, and even a single misdemeanor DUI can make you inadmissible at the border. Border officers use U.S. criminal databases and can turn you away at airports and land crossings. You can apply for individual rehabilitation once at least five years have passed since you completed your entire sentence, including probation and fines. You may also qualify as “deemed rehabilitated” if enough time has passed and the offense carries less than a 10-year maximum sentence in Canada. For urgent trips, a Temporary Resident Permit allows entry with a valid reason.¹⁰

The Real Cost of a Florida DUI

The court fine is usually the smallest line item. Private defense attorneys for a first-offense DUI in Florida typically charge $1,500 to $7,500. FR-44 insurance drives premiums up substantially for three years, with many drivers paying 50% to several hundred percent more than they did before. Add DUI school, the substance abuse evaluation and any treatment, IID installation and monthly monitoring where required, towing and impoundment fees, and court costs, and a first DUI often lands in five figures. None of those costs are tax-deductible; federal tax law bars deducting fines or penalties paid to a government for breaking a law.
