A fourth DUI is a felony in Florida on the count alone. Unlike a second or third offense, there is no time window to fall outside of, no matter how many years separate the priors. A fourth or subsequent DUI is a third-degree felony with prison exposure and permanent license revocation, and a qualifying record can push the sentence higher still.
| Penalty | What the law provides |
|---|---|
| Charge level | Third-degree felony, regardless of how long ago the priors occurred |
| Fine | Not less than $2,000, or not less than $4,000 if the level was 0.15 or higher or a minor was present |
| Prison | Up to 5 years, or longer under the habitual offender statute, section 775.084 |
| License revocation | Permanent, with limited hardship eligibility after 5 years |
| Ignition interlock | 2 years minimum on any reinstated driving privilege |
| DUI school | Level II, with evaluation and treatment |
A fourth or subsequent DUI is a third-degree felony under section 316.193(2)(b), Florida Statutes, no matter when the priors occurred. Program terms last verified June 2026.
No window to fall outside of
The second and third offense levels turn on five-year and ten-year windows. The fourth offense does not. Once the count reaches four, the felony applies regardless of timing, the fine floor rises to $2,000, prison exposure reaches five years, and the license revocation is permanent. A driver with a qualifying record can also face an enhanced sentence under the habitual offender statute.
The defense is the evidence and the priors
With no diversion path available, defending a fourth DUI comes down to the proof. That means scrutinizing each prior conviction the state intends to use, since they are what make the charge a felony, and challenging the stop, the testing, and any statements. Those evidentiary challenges are covered in the blood test, breath test, and search and seizure sections.
Hardship after a permanent revocation
A fourth DUI brings permanent license revocation, but permanent does not always mean forever. Florida allows a path back through the DHSMV after five years, and this is the part many people do not know exists. To qualify, you must show five years with no alcohol use, no driving, and no substance-related arrests, with that period starting after any incarceration ends. The route runs through Special Supervision Services, which requires an ignition interlock device for at least five years, regular reporting, support-group attendance, and random testing for the remainder of the revocation. The same five-year hardship path applies to a DUI manslaughter conviction when there is no prior DUI. These rules come from section 322.271, Florida Statutes. The application steps are covered in the hardship license guide.

Fourth DUI questions
Is a fourth DUI always a felony in Florida?
Yes. A fourth or subsequent DUI is a third-degree felony regardless of how long ago the prior convictions occurred, punishable by up to five years in prison and a fine of at least $2,000. There is no ten-year or five-year window for a fourth offense, the felony applies on the count alone.
What happens to your license on a fourth DUI?
A fourth DUI conviction brings permanent license revocation in Florida. Limited hardship eligibility may exist after five years for a driver who meets strict conditions, but the baseline is a permanent loss of the driving privilege.
Can a fourth DUI bring more than five years?
The base third-degree felony is punishable by up to five years, but a driver with a qualifying record can face a longer sentence under the habitual offender statute, section 775.084. The exposure depends on the full prior record and how the state elects to charge it.
How are the prior DUIs proven?
The state must establish the prior convictions to elevate the charge to a felony. Whether each prior is valid and properly documented is a live issue, and challenging how the priors are proven is part of defending a fourth DUI, alongside the usual challenges to the stop and the testing.
Is diversion possible on a fourth DUI?
No. Diversion programs are reserved for first offenders, so a fourth DUI does not qualify. The defense focuses on the evidence, the validity of the priors, and any basis to suppress the stop, the testing, or the statements.
