A third DUI in Florida becomes a third degree felony when the new offense happens within 10 years of a prior DUI conviction. If both earlier convictions are older than 10 years, the charge usually stays a misdemeanor. That single date comparison decides whether you face state prison, a felony record, and a 10 year license revocation.
The 10 year window runs from the date of your prior conviction to the date of your new offense. It does not run from your arrest date. Out of state DUI convictions can also count toward this total. At Boca Bay DUI Program Inc., we work with repeat offenders every week, and this is the first question we help them understand.
How Florida Law Classifies a Third DUI
Florida Statute 316.193(2)(b)1 sets the rule. A third DUI conviction for an offense within 10 years of a prior conviction is a felony of the third degree. A third DUI outside that window is treated as a misdemeanor with higher fines than a first or second offense.
| Situation | Charge Level | Maximum Jail or Prison |
|---|---|---|
| Third DUI within 10 years of a prior conviction | Third degree felony | Up to 5 years in state prison |
| Third DUI more than 10 years after the prior conviction | Misdemeanor | Up to 12 months in jail |
| Fourth DUI at any time | Third degree felony | Up to 5 years in state prison |
| DUI causing serious bodily injury | Third degree felony | Up to 5 years in state prison |
Prosecutors still need certified records of your prior convictions. When old or out of state records are hard to prove, a felony charge may be reduced. Only your defense attorney can tell you how this applies to your case.
A third DUI within 10 years is only one path to a felony charge. Our guide on whether a DUI is a felony in Florida covers the other situations, such as crashes that cause serious injury.
Penalties for a Felony Third DUI in Florida
A felony third DUI brings both criminal and license penalties. Many of them are mandatory, so the judge has little room to lower them.
Criminal penalties within 10 years:
- A minimum of 30 days in jail, with at least 48 hours served in a row
- Up to 5 years in Florida State Prison
- Fines of $2,000 to $5,000
- Fines of at least $4,000 if your BAC was 0.15 or higher or a minor was in the vehicle
- Up to 5 years of probation
- 90 days of vehicle impoundment or immobilization
- A permanent felony record
A felony conviction also affects your civil rights. Convicted felons in Florida can lose the right to own a firearm, serve on a jury, and hold public office. Voting rights may be restored only after all terms of the sentence are complete.
Penalties for a third DUI outside 10 years:
- Fines of $2,000 to $5,000, or at least $4,000 with a high BAC or a minor present
- Up to 12 months in jail with no mandatory minimum
- Probation, community service, and DUI school
License Revocation After a Third DUI
Your driving privilege takes a heavy hit after a third conviction. Under Florida Statute 322.28(2)(a), a third DUI within 10 years triggers a mandatory 10 year license revocation. You can compare this with first and second offenses in our breakdown of Florida DUI license suspension periods.
| Conviction | Revocation Period | Earliest Hardship Eligibility |
|---|---|---|
| Third DUI within 10 years | 10 years | After 2 years (24 months) |
| Third DUI outside 10 years | 180 days to 1 year | Varies by case |
| Fourth DUI | Permanent | After 5 years, if eligible |
To apply for a hardship license after a 10 year revocation, you must wait 24 months from the revocation date. You also cannot drive or use alcohol or illegal drugs during the 12 months before you apply. Most drivers must also enter Special Supervision Services, which monitors your progress during the restricted period.
Ignition Interlock Requirements
A third DUI conviction requires a Breath Alcohol Ignition Interlock Device (BAIID) for at least 2 years. The device goes on every vehicle you own or lease. You pay for installation, monthly monitoring, and calibration.
Before the engine starts, you blow into the device. If it detects alcohol above the set limit, the car will not start. To learn how monitoring and violations work, read about the role of ignition interlock devices after a DUI in Florida.
DUI School Requirements After a Third DUI
Every Florida DUI conviction requires a state licensed DUI program. For a third offense, you will be placed in the Level 2 DUI course in Florida. This course is for anyone with more than one DUI arrest in their lifetime or anyone who has already attended DUI school.
Level II DUI course at Boca Bay DUI Program Inc.:
- A one hour private evaluation interview
- 4 hours of class on Friday
- 8 hours of class on Saturday
- 8 hours of class on Sunday
- 21 total hours, including the interview
The evaluation decides whether you need substance abuse treatment. If you are referred, you must complete treatment with an approved provider. Skipping treatment can lead to cancellation of your license.
You must finish both the education and evaluation parts within 90 days of enrolling. If you do not, the program must report your failure to the Florida Department of Highway Safety and Motor Vehicles (FLHSMV).

What to Do After a Third DUI Arrest
Acting quickly protects your options. Here are the key steps most drivers should take:
- Hire a DUI defense attorney. Felony exposure makes legal help essential.
- Request your driving record. Confirm the dates of your prior convictions, including any from other states.
- Request an administrative review. You have only 10 days from your arrest to challenge the administrative suspension.
- Enroll in Level II DUI school. The program is required for hardship and full reinstatement.
- Follow all treatment referrals. Treatment completion is reported directly to FLHSMV.
- Plan for an interlock device. Budget for installation and monthly fees.
Frequently Asked Questions
Is a third DUI always a felony in Florida?
No. A third DUI is a felony only when it happens within 10 years of a prior DUI conviction. If your prior convictions are older than 10 years, it is usually a misdemeanor. A fourth DUI is a felony no matter when the priors happened.
How is the 10 year period measured for a third DUI?
The period runs from the date of your prior conviction to the date of the new offense. The arrest date of the earlier case does not control. Your attorney can confirm the exact dates from certified records.
Can I get a hardship license after a third DUI in Florida?
Yes, in some cases. After a 10 year revocation, you must wait 24 months and stay sober and off the road for the 12 months before applying. You must also complete DUI school and Special Supervision Services.
Do out of state DUI convictions count in Florida?
Yes. Florida can count DUI convictions from other states when deciding penalties and license revocation. This is why a full lifetime driving history matters.
