When Does a DUI Become a Felony in Florida?
Eagle Rock Defense Group represents clients facing felony DUI charges throughout Jacksonville and Northeast Florida. Under Florida law, a third DUI arrest can be prosecuted as a third-degree felony, carrying up to five years in prison and a ten-year license revocation.
A third DUI offense within ten years automatically elevates the charge to a third-degree felony in Florida. The state counts convictions chronologically — if your second DUI conviction occurred within ten years of your first, and you now face a third charge within ten years of that second conviction, prosecutors will likely file felony charges regardless of your blood alcohol level or the circumstances of the stop.1

What Makes a DUI a Felony in Florida?
Florida Statute 316.193 classifies a DUI as a third-degree felony when it is the defendant’s third conviction within ten years of a prior conviction, or the fourth conviction regardless of timing.1 The statute does not require injury, property damage, or an elevated BAC — the conviction count alone determines the felony classification. A third-degree felony DUI carries a maximum sentence of five years in prison, five years of probation, or a combination not exceeding five years total.2
The ten-year lookback period begins on the date of the prior conviction, not the date of the prior offense. If you were convicted of your second DUI on March 15, 2020, and arrested for a third DUI on March 10, 2030, the state will prosecute the third charge as a felony even though the arrest occurred five days before the ten-year anniversary. Courts apply this timing strictly, and negotiating a misdemeanor resolution once the felony threshold is crossed requires demonstrating legal deficiencies in the prior convictions or procedural errors in the current case.
What Are the Penalties for a Third DUI in Ten Years?
A third DUI within ten years carries mandatory minimum sanctions: a $2,000 fine (up to $5,000 if BAC was 0.15 or higher), a minimum 30-day jail sentence with at least 48 hours served consecutively, vehicle impoundment for 90 days, and a ten-year driver license revocation.1 The court may impose up to five years in state prison, although judges often sentence defendants to county jail followed by probation when no aggravating factors are present. Probation conditions typically include DUI school, substance abuse treatment, community service, vehicle immobilization, and ignition interlock installation upon license reinstatement.
The ten-year license revocation begins immediately upon conviction. Florida law allows defendants to apply for a hardship license after two years if they complete DUI school and satisfy other DHSMV requirements, but approval is discretionary and many repeat offenders remain without driving privileges for the full decade.34 While many first time felony arrest defendants are offered a withhold of adjudication (meaning no criminal conviction so therefore they are not convicted felons), a conviction for felony DUI is a mandatory conviction. No withhold of adjudication is available. A felony conviction also results in loss of voting rights, firearm possession rights, and professional licensing in many fields until civil rights are restored.
How Does a Fourth DUI Differ From a Third?
A fourth DUI conviction — regardless of how much time has passed since the prior convictions — is always a third-degree felony.1 Florida removes the ten-year lookback window entirely for a fourth offense. Even if your third conviction occurred thirty years ago, a fourth DUI will be prosecuted as a felony with the same statutory maximum of five years in prison with a lifetime driver’s license revocation.. The mandatory minimum fine increases to $2,000, and the court must order vehicle impoundment.
Prosecutors often pursue harsher sentences for fourth-time offenders, particularly when prior convictions include aggravating factors such as accidents, injury, or refusal to submit to testing. Judges view a fourth DUI as evidence of a pattern that standard rehabilitation measures have failed to address, and prison sentences become significantly more likely even in cases involving low BAC and no collateral harm.
Can Prior DUI Convictions Be Challenged?
Yes — defense attorneys routinely investigate whether prior DUI convictions were constitutionally sound, particularly when those convictions elevate a current charge to felony status. Common challenges include lack of proper advisement of rights before entering a plea, ineffective assistance of counsel in the prior case, invalid traffic stops, and procedural errors in prior license suspension hearings. If a prior conviction is set aside, the state loses the basis for felony enhancement and must refile the current charge as a misdemeanor.
The process requires filing a motion to vacate or correct the prior sentence, supported by transcripts and affidavits. Courts grant these motions sparingly, but when the record reveals a clear constitutional violation — such as accepting a guilty plea without establishing a factual basis or failing to advise the defendant of the maximum penalty — vacatur is mandatory. This strategy is most effective when the prior conviction is recent enough that transcripts and witnesses are still available.

What Defenses Apply to Felony DUI Charges?
Felony DUI cases are defended using the same constitutional and technical challenges that apply to misdemeanor DUI, plus additional strategies targeting the validity of prior convictions and the state’s proof of the ten-year timeline. Officers must have reasonable suspicion to initiate the traffic stop and probable cause to arrest for DUI. If the stop was pretextual, the arrest unlawful, or the breath test administered improperly, the current charge may be dismissed regardless of prior conviction history.
Defense counsel also scrutinizes the certified copies of prior convictions the state files to establish felony jurisdiction. Errors in dates, missing signatures on judgments, and discrepancies between court records and DHSMV abstracts can render the prior conviction inadmissible for enhancement purposes. Additionally, if you completed a diversion program or had a prior charge reduced to reckless driving, that disposition does not count as a DUI conviction for enhancement purposes, and the state must proceed as though the prior case never occurred.
| DUI Classification | Conviction Timing | Maximum Penalty | License Revocation |
|---|---|---|---|
| First DUI | First offense | 6 months jail (misdemeanor) | 6 months to 1 year |
| Second DUI (within 5 years) | Second conviction within 5 years of first | 9 months jail (misdemeanor) | 5 years minimum |
| Third DUI (within 10 years) | Third conviction within 10 years of prior | 5 years prison (felony) | 10 years minimum |
| Fourth DUI | Fourth conviction (any time frame) | 5 years prison (felony) | Permanent (hardship after 5 years) |
Frequently Asked Questions
Does a DUI from another state count toward felony enhancement in Florida?
Yes. Florida law counts out-of-state DUI convictions when calculating whether a current charge qualifies as a third or fourth offense. The state will obtain certified copies of convictions from other jurisdictions and use them for enhancement purposes, provided the out-of-state offense would have qualified as DUI under Florida law.
Can I get a hardship license while my felony DUI case is pending?
Eligibility depends on your prior suspension history and whether you refused testing. If this is your first administrative suspension or you submitted to testing, you may apply for a hardship license after the initial 30-day hard suspension. Repeat offenders and refusal cases face longer waiting periods and stricter conditions, and approval is never guaranteed.
Will I go to prison for a third DUI?
Not necessarily. While a third DUI within ten years is a felony carrying up to five years in prison, judges often impose county jail followed by probation when the defendant has no violent criminal history and the DUI involved no accident or injury. Each case is evaluated individually based on BAC level, criminal record, and willingness to complete treatment.
Can a felony DUI charge be reduced to a misdemeanor?
Reduction is possible. Prosecutors may agree to refile or downgrade the felony charge to a misdemeanor if the defense demonstrates that a prior conviction used for enhancement is legally invalid, or if the current case has significant proof problems such as an illegal stop or inadmissible breath test. Negotiating a reduction requires identifying concrete legal deficiencies, not merely arguing for leniency.
How long does a DUI conviction stay on my record in Florida?
Permanently. Florida does not allow expungement or sealing of DUI convictions, whether misdemeanor or felony, because a conviction for DUI is mandatory. A withhold of adjudication is illegal under Florida law for a misdemeanor or felony DUI conviction.. The conviction remains on your criminal record and driving record for life and will be visible to employers, licensing boards, and law enforcement indefinitely. This is why defending aggressively against every DUI charge — even a first offense — is critical.
