Florida DUI Laws

Driving under the influence (DUI) in Florida is a serious offense that comes with serious penalties. According to Florida Statutes § 316.193(1), a person can be charged with DUI if they are driving or in control of a vehicle in the state while under the influence of any of the following to the extent their normal faculties are impaired:

• any alcoholic beverage;
• any controlled substance;
• any chemical substance listed in Chapter 877.111; or
• a combination of any of the above.

Alternatively, a person can be charged with DUI, regardless of impairment, if their blood-alcohol level is 0.08 or higher or if their breath-alcohol level is 0.08 or higher, regardless of their level of impairment (sometimes called the “pre se” or “DUBAL” version of DUI).

Depending on how the DUI offense is charged, the number and timing of prior convictions, and the existence of certain aggravating factors, the minimum and maximum penalties the court must impose at sentencing escalate, including:

• the period of probation or incarceration;
• the fines;
• the length of time required for the revocation of driving privileges;
• the length of time required for the immobilization of the vehicle; and
• the length of time required for the ignition interlock device to be installed.

Penalties for Aggravating Factors Present During the DUI

In Florida, DUI penalties increase for other aggravating circumstances, such as a person’s blood-alcohol or breath-alcohol level of 0.15 or higher or a minor present in the vehicle. Subsections (2), (3), and (4) delineate various penalties for certain aggravating conduct.

Other provisions increase fines and imprisonment terms based on certain factors present during the DUI episode. For example, § 316.193(4) provides for increased fines and terms of imprisonment if the person, while driving under the influence, had a blood-alcohol level (BAC) or breath-alcohol level (BrAC) of 0.15 or higher or was accompanied by a minor.

Section 316.193(3)(c) contains several provisions detailing certain aggravating conduct with corresponding increases in punishment as the harm caused by the DUI driver increases:

1. Damage to the property or person of another commits a misdemeanor of the first degree, punishable as provided in s. 775.082 or s. 775.083;
2. Serious bodily injury to another, as defined in s. 316.1933, commits a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084;
3. The death of any human being or unborn child commits DUI manslaughter and commits:
   • A felony of the second degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.
   • A felony of the first degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084, if:
     • At the time of the crash, the person knew, or should have known, that the crash occurred; and
     • The person failed to give information and render aid as required by s. 316.062.
