Overview
Florida takes an aggressive stance on drunk driving, with mandatory minimum jail sentences even for first offenses when BAC is 0.15 or higher. The state uses a 'no lookback' lifetime priors system — meaning any prior DUI conviction from any time period counts toward escalating penalties. Florida also imposes some of the longest ignition interlock device (IID) requirements in the Southeast and mandates vehicle impoundment for repeat offenders. A fourth DUI in Florida is always a felony regardless of when the prior offenses occurred, making it critical to understand the full scope of consequences.

Implied Consent Law
Under Florida Statute §316.1932, any person who operates a motor vehicle in Florida is deemed to have consented to chemical or physical testing of breath, blood, or urine if lawfully arrested for DUI. Law enforcement must inform the driver that refusal will result in license suspension.
Refusal penalties: First refusal: 1-year license suspension. Second or subsequent refusal: 18-month license suspension AND a first-degree misdemeanor charge (up to 1 year in jail and $1,000 fine). Refusal can also be used as evidence against the driver in court.
Aggravating Factors

| DUI causing property damage | First-degree misdemeanor; up to 1 year in jail and $1,000 in fines in addition to DUI penalties |
| DUI causing serious bodily injury | Third-degree felony; up to 5 years in prison and $5,000 in fines |

Underage DUI
Drivers under 21 with BAC of 0.02% or higher face automatic 6-month license suspension for a first violation, 1-year suspension for a second. If BAC is 0.05% or higher, the driver must also complete a substance abuse evaluation and course. If BAC reaches 0.08%, full adult DUI penalties apply in addition to underage penalties.
Diversion Programs
Program: DUI Diversion / Back on Track Programs
Several Florida counties offer pre-trial diversion programs for first-time DUI offenders. These programs typically require completion of DUI school, substance abuse treatment, community service, random testing, and a monitoring period of 6–12 months. Successful completion may result in charges being reduced or dismissed.
Eligibility: Generally limited to first-time DUI offenders with BAC under 0.15%, no accident involving injury, no minor in the vehicle, and no prior criminal history. Availability and specific requirements vary by county — programs exist in Miami-Dade (Back on Track), Hillsborough, and other counties but are not available statewide.
