DUI & Traffic Violations in Florida: what to sort out first, the points where the file most often starts drifting, and what usually shifts earliest

Florida DUI law is governed by Fla. Stat. § 316.193. Like Texas (but calling it DUI rather than DWI), Florida defines impairment broadly — "under the influence to the extent that the person's normal faculties are impaired" is the subjective prong, while the 0.08% BAC is the per se prong. Either theory supports conviction independently. Florida also has a separate enhanced DUI category for BAC at or above 0.15%, which carries doubled minimum fines and mandatory ignition interlock device requirements regardless of whether the defendant would otherwise qualify for IID.

Florida's DUBAL: The Elevated BAC Enhancement

Florida's "DUBAL" (Driving with Unlawful Blood Alcohol Level) provisions create an automatic enhancement when a driver's BAC tests at 0.15% or above. For a first DUI conviction with BAC ≥ 0.15%: minimum fine doubles to $1,000–$2,000 (from the standard $500–$1,000), mandatory IID for at least 6 months, and more restrictive probation terms. For a second conviction with BAC ≥ 0.15%, IID is mandatory for at least 2 years. The enhancement also applies when a person under 18 is in the vehicle at the time of the DUI — the presence of a child passenger triggers the same doubled minimums regardless of BAC level.

License Suspension and the Administrative Process

After a Florida DUI arrest, the arresting officer takes the driver's license and issues a 10-day driving permit. Two tracks then run simultaneously. The criminal track is in the county court. The administrative track — the formal review hearing to contest license suspension — must be requested from the DHSMV (Department of Highway Safety and Motor Vehicles) within 10 days of the arrest. Missing the 10-day DHSMV hearing request deadline results in automatic suspension without any hearing, just as in California.

Suspension lengths: first DUI offense — 180 days (failure) or 1 year (refusal). Second DUI within 5 years — 5-year revocation. Third DUI within 10 years — 10-year revocation. Fourth or subsequent DUI (any time frame) — permanent revocation. Florida's escalating revocation schedule is among the harshest for repeat offenders.

Implied Consent and Refusal

Florida's implied consent law (Fla. Stat. § 316.1932) requires drivers to submit to breath, blood, or urine testing upon lawful DUI arrest. Refusal to submit: first refusal — 1-year license suspension and refusal is admissible as evidence of guilt. Second refusal — 18-month suspension and refusal is a first-degree misdemeanor (criminal charge, not just an administrative consequence). Florida is one of the few states that criminalizes a second test refusal — a driver who previously refused is facing a separate criminal charge simply by refusing again.

DUI Manslaughter: Second-Degree Felony in Florida

DUI manslaughter (Fla. Stat. § 316.193(3)(c)) is a second-degree felony in Florida — 15 years maximum, with a mandatory minimum of 4 years when the defendant knew or should have known of the accident and failed to remain at the scene. If the defendant left the scene, the mandatory minimum rises to 4 years. DUI manslaughter with failure to render aid (leaving the scene) is elevated to a first-degree felony with a minimum mandatory of 4 years. Florida's DUI manslaughter sentences are among the most severe in the country for drunk driving death cases.

DUI Diversion Programs

Several Florida counties operate DUI diversion programs for first-time offenders. Miami-Dade, Broward, Palm Beach, and other major counties offer diversion programs where a first-time DUI defendant completes education, community service, treatment evaluation, and other requirements in exchange for charge reduction or dismissal. Eligibility criteria vary by county — BAC level, prior record, and whether an accident occurred all affect eligibility. Not every Florida county has a diversion program, and not every first-time DUI defendant qualifies even where a program exists.
