A DUI arrest in Florida sets off a legal process that moves on two separate tracks — one through the criminal court system and one through the Florida Department of Highway Safety and Motor Vehicles (DHSMV). Understanding how those tracks work, and why many people facing DUI charges in Florida seek legal representation, starts with knowing what's actually at stake.
Florida defines driving under the influence (DUI) as operating a vehicle while impaired by alcohol, chemical substances, or controlled substances, or with a blood alcohol concentration (BAC) of 0.08% or higher. For commercial drivers, the threshold drops to 0.04%. For drivers under 21, Florida applies a zero-tolerance standard — a BAC of 0.02% or higher can trigger administrative penalties.
The charge can apply whether the vehicle was moving or simply in operation with the driver in control of it.
Most people don't realize a DUI arrest in Florida immediately triggers two separate proceedings:
1. The Criminal Case This is handled through the state court system. The outcome determines whether a conviction goes on the driver's record, what fines and jail time may apply, and whether probation or mandatory programs are required.
2. The DHSMV Administrative Review This runs independently of the criminal case. When a driver is arrested for DUI in Florida, their license is typically suspended on the spot. The driver has 10 days from the date of arrest to request a formal review hearing with the DHSMV — or that right is waived. This administrative process can result in a hardship license for some drivers even during a suspension period.
These timelines are strict. Missing the administrative hearing window has consequences that are separate from anything that happens in court.
An attorney handling DUI defense in Florida typically:
The earlier an attorney is involved, the more time they have to address both tracks — especially since the administrative window closes quickly.
Florida law distinguishes between DUI charges based on factors like prior convictions, BAC level, and whether anyone was injured or killed.
| Charge Type | Common Circumstances |
|---|---|
| First-offense misdemeanor DUI | First arrest, BAC under 0.15%, no accident or injury |
| Enhanced first-offense | BAC of 0.15% or higher, or minor in the vehicle |
| Second-offense DUI | Prior DUI conviction on record |
| Felony DUI | Third or subsequent offense, or DUI involving serious injury or death |
Penalties escalate significantly across these categories and can include mandatory minimum jail time, ignition interlock device requirements, extended license revocations, and vehicle impoundment. A prior DUI conviction — even from another state — can affect how Florida charges and sentences a new offense.
Florida's administrative suspension following a DUI arrest operates on a specific structure:
A hardship license (also called a Business Purposes Only license) may be available depending on the offense and the driver's history, allowing driving for work, school, or medical appointments. Eligibility varies.
If a DUI conviction results, Florida imposes penalties that go beyond fines and license suspension. Mandatory DUI school, probation, community service hours, and ignition interlock device installation are common requirements depending on the offense level. Some programs offer first-time offenders a diversion or reduction opportunity — but these are not available to everyone and depend on the specific facts and the jurisdiction within Florida.
Beyond the immediate penalties, a DUI conviction in Florida stays on a driver's permanent record. Florida does not permit expungement or sealing of DUI convictions. That has implications for employment, professional licensing, background checks, and insurance rates.
Unlike personal injury cases — where attorneys often work on contingency — DUI defense attorneys in Florida typically charge flat fees or hourly rates. The cost varies based on the complexity of the case, whether it goes to trial, and the attorney's experience. A case involving a felony charge, accident injuries, or a refusal to submit to testing will generally cost more to defend than a straightforward first-offense misdemeanor.
No two DUI cases follow the same path. Outcomes depend on factors including:
What applies in Miami-Dade may differ meaningfully from how a case proceeds in a smaller Florida county. The specific facts of the arrest and what happened before, during, and after it are the details that actually determine what's possible in any individual case.
