A DUI arrest in Miami sets off a legal process that moves quickly and on multiple tracks at once. There's the criminal case — handled through the court system — and there's the administrative case, handled separately through the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). Understanding how each works helps you make sense of what's happening and what decisions are ahead.
In Florida, a DUI charge applies when a driver is operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher, or while impaired by alcohol or controlled substances regardless of BAC. For commercial drivers, the limit is 0.04%. For drivers under 21, Florida's zero-tolerance law sets it at 0.02%.
Miami-Dade County processes DUI cases through the Miami-Dade Criminal Court system. The process typically includes:
Most DUI cases don't go to trial. Many resolve through negotiated pleas, diversion programs, or motions that challenge the legality of the stop, the field sobriety testing, or the BAC evidence itself.
This is one of the most misunderstood parts of a DUI arrest in Florida. The moment you are arrested for DUI — and either refuse a breath test or blow 0.08% or above — your license faces automatic administrative suspension through the FLHSMV.
You have only 10 days from the arrest date to request a formal review hearing to challenge that suspension. Missing that window generally means the suspension goes into effect automatically.
This administrative process runs independently of your criminal case. You can be acquitted in criminal court and still lose your license on the administrative side — and vice versa.
| Situation | Suspension Length (First Offense) |
|---|---|
| BAC of 0.08% or higher | 6 months |
| Refusal to submit to testing | 1 year |
| Second refusal | 18 months |
These are Florida's general parameters. Actual outcomes depend on prior history, case facts, and whether the suspension is successfully challenged.
A DUI lawyer in Miami typically evaluates your case across several dimensions:
Challenging the traffic stop. Law enforcement must have lawful grounds to stop your vehicle. If the stop is found to be without reasonable suspicion, evidence gathered afterward may be subject to suppression.
Challenging field sobriety tests. Standardized Field Sobriety Tests (SFSTs) — like the walk-and-turn or one-leg stand — have specific administration requirements. Deviation from those standards can affect their reliability as evidence.
Challenging breathalyzer results. Breath test machines require calibration and proper maintenance. Testing procedures must follow specific protocols. Attorneys often scrutinize these records as part of their defense strategy.
Negotiating with prosecutors. Depending on the facts, a defense attorney may negotiate for reduced charges (such as reckless driving, sometimes called a "wet reckless"), alternative sentencing, or entry into a pre-trial diversion program where available.
Handling the FLHSMV hearing. Many DUI attorneys in Miami handle both the criminal and administrative sides, representing clients at formal review hearings to contest the license suspension.
Florida law draws significant distinctions based on prior DUI history.
| Offense Level | Potential Penalties (General Range) |
|---|---|
| First offense | Fines, probation, community service, DUI school, possible jail |
| First offense with BAC ≥ 0.15% or minor in vehicle | Enhanced fines, mandatory ignition interlock |
| Second offense | Longer license revocation, mandatory jail time possible |
| Third offense (within 10 years) | Felony charge possible |
| DUI with serious bodily injury | Felony |
| DUI manslaughter | Serious felony with significant mandatory minimums |
Exact sentencing depends on the judge, the prosecutor, the facts, prior record, and how the case is resolved.
After an arrest, a defense attorney in Miami will typically:
No two DUI cases are identical. Outcomes vary based on:
Each of these variables affects not just the severity of potential penalties, but also what defenses are available and how prosecutors are likely to approach the case.
Beyond the immediate administrative suspension, a DUI conviction in Florida triggers a court-ordered revocation that runs separately. Reinstatement typically requires completing DUI school, paying reinstatement fees, and — for certain offenses — installing an ignition interlock device. An IID requires the driver to pass a breath test before the vehicle will start.
Florida also reports DUI convictions to other states through the Driver License Compact, meaning out-of-state drivers and Florida residents who drive in other states may face consequences beyond Florida's borders.
The intersection of the criminal case, the administrative license action, court-ordered requirements, and insurance consequences means that what looks like a single event — a DUI arrest — actually has several separate outcomes, each governed by its own rules and timelines.
