Florida DUI laws set the legal blood alcohol limit at 0.08% for drivers 21 and older under Florida Statutes Section 316.193. A first conviction can bring a fine between $500 and $1,000 and up to 6 months in jail. A driver can also be charged based on impairment alone, without meeting the 0.08% number. This guide covers penalties, license suspension, implied consent, and the 2025 changes under Trenton’s Law. The primary source is the Florida Department of Highway Safety and Motor Vehicles.

Key Terms in Florida DUI Law
Florida DUI law relies on a few terms that shape how a charge applies. Actual physical control means a person can be charged with DUI without the vehicle moving, such as sitting in the driver’s seat with access to start the engine. Implied consent means that holding a Florida driver’s license already means agreeing to a lawful breath, blood, or urine test if arrested for DUI. Per se DUI means a charge based only on a measured alcohol level of 0.08% or higher, regardless of visible impairment.
These terms often cause confusion because many drivers assume DUI only applies while a car is actively moving on a road. Florida Statutes Section 316.193 defines DUI as driving or being in actual physical control of a vehicle within the state while impaired or while at or above the 0.08% threshold. This broader definition means a parked vehicle with the engine accessible can still lead to a valid DUI charge under Florida law.
What Florida Law Says About DUI
Under Florida Statutes Section 316.193, a person is guilty of DUI if they are driving or in actual physical control of a vehicle while impaired by alcohol, a controlled substance, or a chemical substance, or while their blood alcohol level or breath alcohol level is 0.08% or higher. The penalties are the same regardless of which method is used to prove the offense. This means impairment based on observed conduct and a measured 0.08% reading carry identical legal consequences.
A driver does not need to appear impaired to be charged if a breath or blood test shows 0.08% or higher. This is the per se standard, and it removes the need for prosecutors to show visible signs of intoxication in those cases. Impairment based DUI instead relies on evidence such as field sobriety exercises, officer observations, and witness accounts of how the person operated or controlled the vehicle.
Who Florida DUI Law Applies To
Florida DUI law applies to any driver operating or in actual physical control of a vehicle within the state, based on the general 0.08% threshold for drivers 21 and older. Different thresholds apply to certain groups. Commercial motor vehicle operators face alcohol related disqualification under Florida Statutes Section 322.61 at a blood alcohol level of 0.04% or above, a lower number than the general driver standard, reflecting stricter rules for commercial licensing.
The statute’s language covering “within this state” is applied broadly, extending DUI enforcement beyond public roads to include private property such as parking lots where a vehicle could be operated. This means a person does not need to be on a public highway for Florida DUI law to apply, as long as they are driving or in actual physical control of a vehicle somewhere within Florida’s jurisdiction.
Florida DUI Penalties for a First Offense
A first DUI conviction under Florida Statutes Section 316.193 carries a fine of not less than $500 and not more than $1,000. If the blood alcohol level or breath alcohol level was 0.15% or higher, or if a minor was in the vehicle, the fine range increases to between $1,000 and $2,000. Jail exposure for a first conviction is up to 6 months, or up to 9 months if the higher alcohol level or minor passenger factors apply.
A first conviction also carries a required period of probation not to exceed 1 year, which includes a mandatory minimum of 50 hours of community service under Florida Statutes Section 316.193. The court also orders vehicle impoundment or immobilization for 10 days as a condition of probation, unless the defendant’s family has no other transportation available, in which case the court may dismiss that portion of the order.
Penalties for Second and Third DUI Convictions
A second DUI conviction carries a fine between $1,000 and $2,000, rising to between $2,000 and $4,000 if the alcohol level was 0.15% or higher or a minor was present. Jail exposure increases to up to 9 months, or up to 12 months with those aggravating factors. If the second conviction occurs within 5 years of the first, the court must order a mandatory minimum of 10 days imprisonment, with at least 48 hours served consecutively.
A third conviction within 10 years of a prior conviction is classified as a third degree felony under Florida Statutes Section 316.193, punishable as provided in Florida Statutes Section 775.082, Section 775.083, or Section 775.084. This carries a fine of not more than $5,000 and up to 5 years imprisonment. A third conviction occurring more than 10 years after the second is generally punished at penalty levels similar to a first offense.
Felony DUI and Aggravated Circumstances
Florida DUI law elevates certain offenses to felony status under specific conditions described in Florida Statutes Section 316.193. A fourth or subsequent DUI conviction is a third degree felony regardless of how much time has passed since any prior conviction, with a fine of not less than $2,000 and up to 5 years imprisonment. A DUI that causes serious bodily injury to another person is also a third degree felony under the same statute.
A DUI that causes property damage or personal injury without reaching the serious bodily injury threshold is a first degree misdemeanor, punishable by up to $1,000 in fines or up to 1 year in jail under Florida Statutes Section 316.193 together with Section 775.082 and Section 775.083. These aggravated categories reflect Florida’s approach of scaling penalties to the severity of harm caused rather than treating every DUI charge identically.
DUI Manslaughter and Vehicular Homicide
DUI manslaughter under Florida Statutes Section 316.193 is a second degree felony, punishable by up to $10,000 in fines and up to 15 years imprisonment, and it carries a mandatory minimum term of 4 years imprisonment. If the driver knew or should have known a crash occurred and failed to give information or render aid as required under Florida Statutes Section 316.062, the charge becomes a first degree felony punishable by up to $10,000 and up to 30 years imprisonment.
Vehicular homicide carries penalty structures similar to DUI manslaughter, including a second degree felony classification with up to 15 years imprisonment, or a first degree felony with up to 30 years imprisonment if the driver left the scene of the crash. As explained later in this guide, Trenton’s Law increased penalties further for repeat offenders convicted of these specific manslaughter and homicide charges.
Administrative License Suspension in Florida
Florida operates a two track system after a DUI arrest. A criminal case proceeds through the courts, while a separate administrative suspension is handled by the Florida Department of Highway Safety and Motor Vehicles under Florida Statutes Section 322.2615. This administrative suspension applies to drivers 21 and older with an alcohol level of 0.08% or above and takes effect immediately after arrest, independent of any later court outcome.
A first administrative suspension under this process is generally 6 months. A second or subsequent administrative suspension for an alcohol level at or above the threshold is generally 1 year. These administrative penalties are separate from license revocation periods ordered later by a court following a conviction, and the two time periods should not be treated as the same suspension.
The 10 Day Review Window and Hardship Licenses
A driver has 10 calendar days from the date of arrest to request a formal or informal review hearing to challenge the administrative suspension under Florida Statutes Section 322.2615. Missing this window generally forfeits the opportunity to contest the administrative suspension before a hearing officer, making this one of the more time sensitive deadlines connected to a Florida DUI arrest.
A hardship license may become available for business or employment purposes after certain conditions are met, including proof of enrollment in DUI school. For a first conviction with an unlawful alcohol level, a driver must generally serve 30 days without a license before becoming eligible for hardship reinstatement. Hardship licenses are not available after a second or subsequent test refusal or after two or more DUI convictions.
Court Ordered License Revocation Periods
Court ordered license revocation is separate from the administrative suspension and follows conviction under Florida Statutes Section 322.271 and Section 322.28. A first offense without bodily injury carries a minimum 180 day revocation and a maximum of 1 year. A first offense involving bodily injury carries a minimum 3 year revocation, reflecting the added severity when a DUI causes harm to another person.
A second offense within 5 years of a prior conviction carries a minimum 5 year revocation, with possible hardship reinstatement after 1 year. A third offense within 10 years of the second conviction carries a minimum 10 year revocation, with possible hardship reinstatement after 2 years. A fourth conviction, regardless of timing between offenses, carries mandatory permanent revocation, with possible hardship reinstatement after 5 years.
Implied Consent and Chemical Testing
Florida Statutes Section 316.1932 establishes the implied consent law, meaning that by driving in Florida, a person has already agreed to submit to a lawful breath, blood, or urine test if arrested for DUI. Refusal to submit to this testing is admissible as evidence in a DUI criminal proceeding, separate from any administrative consequences tied to the refusal itself.
Before Trenton’s Law took effect, a first refusal to submit to testing triggered a 1 year administrative license suspension without a separate criminal charge, while a second or subsequent refusal was already treated as a misdemeanor. The Florida DUI and Administrative Suspension Laws (FLHSMV) page confirms these suspension periods as part of the state’s official summary of Florida Statutes Section 316.1932 and Section 316.1939.
Trenton’s Law and the 2025 Changes to Refusal Penalties
Effective October 1, 2025, Florida enacted House Bill 687, known as Trenton’s Law, which became Chapter 2025-121 and amended Florida Statutes Section 316.1932 and Section 316.1939. Under this change, a first refusal to submit to a lawful breath or urine test following a DUI arrest is now also a criminal offense, in addition to the existing 1 year administrative license suspension that already applied to first refusals.
Trenton’s Law applies only to refusals and offenses occurring on or after October 1, 2025, and does not apply retroactively to arrests or refusals that happened before that date. Officers are now required to inform drivers that refusal carries potential criminal consequences, not only the administrative suspension that applied under the prior version of Florida Statutes Section 316.1932. Full statutory text is available through House Bill 687 (2025) Bill History, The Florida Senate.
Trenton’s Law Changes to Manslaughter and Homicide Penalties
Trenton’s Law also amended Florida Statutes Section 316.193 to enhance penalties for DUI manslaughter when the person has a prior conviction for DUI manslaughter, boating under the influence manslaughter, vehicular homicide, or vessel homicide. In these repeat conviction cases, the charge is elevated from a second degree felony to a first degree felony, doubling the maximum prison exposure from 15 years to 30 years.
Companion amendments under Chapter 2025-121 apply parallel enhancements to Florida Statutes Section 327.35, covering boating under the influence manslaughter, and Florida Statutes Section 782.071, covering vehicular homicide. These enhancements apply specifically to repeat convictions involving a death, not to standard DUI charges without a fatality. The full enacted text is available through Chapter 2025-121, Laws of Florida (Trenton’s Law full text).
Ignition Interlock Device Requirements
Florida Statutes Section 316.1938 governs ignition interlock devices, which are breath testing devices installed in a vehicle that prevent the engine from starting if alcohol is detected. A second DUI conviction requires mandatory installation for at least 1 year at the convicted person’s expense. A third conviction within 10 years of a prior conviction requires installation for not less than 2 years.
Courts may also order an ignition interlock device for a first conviction involving an alcohol level of 0.08% or higher, for a period of at least 6 continuous months, even though this is not automatically required for every first offense. When a conviction involves a blood alcohol level of 0.15% or higher or a minor passenger, mandatory interlock periods increase to at least 6 months for a first offense and at least 2 years for a second offense.
Common Exceptions and Misconceptions in Florida DUI Cases
A common misconception is that DUI only applies to a person actively driving on a public road. Florida Statutes Section 316.193 instead applies broadly to actual physical control within the state, which can include parked vehicles on private property such as parking lots. Another misconception is that refusing a breath test avoids all legal consequences, when in fact implied consent under Florida Statutes Section 316.1932 already attaches administrative penalties to any refusal.
Some drivers also assume the administrative license suspension and the court ordered revocation are the same penalty, when they are governed by separate statutes and separate timelines. The administrative suspension under Florida Statutes Section 322.2615 begins immediately after arrest, while court ordered revocation under Florida Statutes Section 322.271 and Section 322.28 only follows a conviction. Laws and enforcement may change, so drivers should check official state sources for the latest rules, particularly given the 2025 changes described in this guide.
