How Long Do You Stay in Jail for a DUI in Florida?

How long you stay in jail for a DUI in Florida depends on whether it’s your first offense or a repeat, how high your blood-alcohol level was, whether anyone was hurt, and whether a child was in the car. A clean first offense carries up to six months but no mandatory minimum, so many first-time offenders serve no jail time at all beyond the hours after arrest. Repeat offenses trigger mandatory minimums a judge cannot waive, and a DUI that kills someone carries a four-year mandatory prison sentence.

The Hours Right After Arrest

Before any sentence enters the picture, Florida law requires that a person arrested for DUI stay in custody until they are no longer impaired. In practice, that means at least several hours after booking. A first appearance before a judge, where bail is typically set, generally happens within 24 hours. For a standard misdemeanor DUI with no aggravating factors, release usually happens inside that first day.

Timing matters. If you’re arrested on a Friday night, your first appearance may not come until Monday, and you’ll spend the weekend in jail waiting for it.

First-Offense DUI

A standard first DUI in Florida is a misdemeanor punishable by up to six months in jail and a fine between $500 and $1,000.¹ There is no mandatory minimum, which means the judge can skip jail entirely.

Most first-time offenders are placed on probation instead. The court can order up to one year of probation along with at least 50 hours of community service.² The combined total of probation and any incarceration cannot exceed one year. You’ll also complete a DUI education course and a substance abuse evaluation, and if the evaluation recommends treatment, you’re expected to follow through.

Second DUI

Penalties jump significantly for a second offense, especially when it falls within five years of the first conviction. A second DUI inside that window carries a mandatory minimum of 10 days in jail, with at least 48 consecutive hours served without interruption.³ The maximum sentence is nine months, and fines run from $1,000 to $2,000.¹

If more than five years have passed since the first conviction, the 10-day mandatory minimum doesn’t apply. The maximum sentence and fine range stay the same, but the judge has more flexibility.

Third and Fourth Offenses

A third DUI within 10 years of a prior conviction crosses from misdemeanor into felony territory. It’s a third-degree felony punishable by up to five years in state prison, with a mandatory minimum of 30 days in jail.¹⁴

If the third DUI occurs more than 10 years after the prior conviction, it’s treated as a misdemeanor with a fine of $2,000 to $5,000 and up to 12 months in jail.¹

A fourth DUI is always a third-degree felony, regardless of how much time has passed between any of the prior offenses. No lookback period applies. The maximum sentence is five years in prison.¹

Aggravators That Push Jail Time Higher

High BAL or a Child in the Car

If your blood-alcohol level was 0.15 or higher, or you had a passenger under 18 in the vehicle, the maximum jail sentence for a first offense rises from six to nine months, with fines of $1,000 to $2,000. A second offense with either aggravator carries up to 12 months and fines of $2,000 to $4,000.²

Injury or Death

When a DUI causes property damage or minor injury to another person, the charge becomes a first-degree misdemeanor carrying up to one year in jail. Serious bodily injury pushes the charge to a third-degree felony with up to five years in prison.²

DUI manslaughter is a second-degree felony carrying a four-year mandatory minimum and a maximum of 15 years.²⁴ Leaving the scene after a fatal crash elevates the charge to a first-degree felony punishable by up to 30 years in prison. The four-year mandatory minimum on manslaughter is firm: the judge cannot go below it, even for a defendant with an otherwise clean record.

Ways to Avoid or Reduce Jail Time

Florida courts have some flexibility to keep certain DUI offenders out of jail, particularly on a first offense. The most common path is probation, which can last up to one year with conditions like regular reporting, community service, DUI school, and substance abuse treatment.²

A judge can also order you to serve part or all of a jail sentence in a residential substance abuse treatment program, with that time counting toward the sentence imposed.⁵ This isn’t offered in every case, and it’s more realistic for first and second offenders than for someone facing felony charges.

Neither alternative overrides a mandatory minimum. If you’re facing a required 10-day or 30-day sentence, probation alone won’t satisfy it. The mandatory portion has to be served one way or another, whether in jail or in an approved residential setting.
