Florida DUI Law: Fla. Stat. § 316.193

Florida’s DUI statute, § 316.193, Florida Statutes, defines the offense of Driving Under the Influence. A person commits DUI if they are driving or in actual physical control of a vehicle and either:

1. Are under the influence of alcoholic beverages, a chemical substance, or a controlled substance to the extent that their normal faculties are impaired; or
2. Have a blood-alcohol level (BAL) or breath-alcohol level (BrAC) of 0.08 or higher (0.02 for drivers under 21; 0.04 for commercial drivers).

Penalties escalate quickly with prior offenses, accidents, minors in the vehicle, or very high BAL readings. A DUI conviction in Florida cannot be sealed or expunged, which makes fighting the charge at the outset especially important.

Potential Penalties for a Florida DUI

The exact penalty depends on priors, BAL, and case facts. Florida’s DUI framework generally includes:

Collateral consequences can include insurance surcharges, employment impact (especially for CDL holders and professional licensees), immigration consequences for non-citizens, and long-term license and background-check effects.

Driver’s License Suspension After a Florida DUI Arrest

A critical aspect of any DUI case in Florida involves the driver’s license. Under Florida’s implied consent law (Fla. Stat. § 316.1932), you are deemed to have consented to approved chemical tests when lawfully arrested for DUI. Refusing a breath or urine test carries administrative consequences and, as of October 1, 2025, criminal consequences as well — see the FAQ below.

Bernhardt Riley, Attorneys at Law, PLLC, is adept at navigating these processes, including assisting first-time offenders in applying for hardship licenses. See our related page on driving while license suspended or revoked.

What the State Must Prove in a Florida DUI Case

In a DUI prosecution, the state bears the burden of proof beyond a reasonable doubt. To convict, the state must generally establish:

• Identity — the defendant was the person driving or in actual physical control
• Driving or actual physical control — this is broader than active driving; case law addresses parked vehicles, keys in ignition, and similar scenarios
• Impairment — either under the influence to the extent that normal faculties were impaired, or a BAL/BrAC above the legal limit
• Jurisdiction and venue
• Admissibility of chemical test results — proper operator certification, instrument maintenance records, 20-minute observation period, and compliance with Florida Administrative Code provisions governing approved instruments

Any weakness in these elements is a potential defense.

Common DUI Defense Strategies

Florida’s stringent DUI laws mean that a conviction carries serious consequences — but not every DUI case is clear-cut. Defense strategies often include:

• Challenging the stop — whether the officer had reasonable suspicion to initiate the traffic stop
• Challenging the arrest — whether there was probable cause to arrest for DUI
• Field sobriety test (FST) issues — NHTSA standardization, officer training, environmental conditions, medical conditions, and footwear
• Breath test challenges — Intoxilyzer 8000 maintenance records, operator certification, 20-minute observation period, mouth alcohol, radio-frequency interference, and slope detector issues
• Blood test challenges — chain of custody, lab accreditation, vial preservatives, and phlebotomist qualifications
• Video evidence — dash-cam and body-cam footage can contradict officer reports
• Medical conditions — GERD, diabetes, ketosis, neurological conditions
• Rising BAL defense — alcohol absorbed after driving
• Miranda and statement-suppression issues
• Improper DUI checkpoints — compliance with constitutional and statutory standards

Each case varies, and a tailored defense strategy depends on the police reports, video, breath-test records, and witness accounts. See our overview of criminal defense for related charges and defenses.

DUI Enhancements and Related Charges

DUI cases often bring related or enhanced charges, including:

• DUI with property damage or serious bodily injury
• DUI manslaughter
• Leaving the scene of an accident (hit-and-run)
• Reckless driving (sometimes negotiated as a reduced charge)
• Driving with a suspended license (DWLS / DWLSR)
• Child endangerment when minors are passengers
• Refusal enhancement on a second or subsequent refusal

Steps to Take Immediately After a Florida DUI Arrest

Frequently Asked Questions About Florida DUI Charges

What is the legal blood-alcohol limit in Florida?

Under Fla. Stat. § 316.193, the legal limit is 0.08 for most drivers, 0.02 for drivers under 21, and 0.04 for commercial driver’s license (CDL) holders. A reading above the limit creates a per-se DUI, but the state can also prove DUI based on impairment alone, even below the per-se limit.

What are the common defenses against a DUI charge in Florida?

Common defenses include challenging the legality of the stop, challenging probable cause for arrest, questioning the accuracy of breath or blood tests, raising issues with field sobriety test administration, and presenting evidence of medical conditions or non-alcohol causes of observed behavior. Each case is fact-specific.

What are the steps to take immediately following a DUI arrest?

Contact a DUI defense attorney, request a Formal Administrative Review Hearing within 10 days (or, if you qualify, apply for a “business-purposes only” license instead), document everything you recall about the stop and arrest, and avoid discussing your case with anyone other than your attorney. Stay off social media about the case.

Why is quick action essential within 10 days of a DUI arrest?

Florida law gives you only 10 days from arrest to either request a Formal Administrative Review Hearing to contest your driver’s license suspension, or — if you qualify — waive that review and apply for a “business-purposes only” license. Failing to act within this window can result in an automatic administrative suspension, regardless of the outcome of the criminal case.

Can I refuse a breath test in Florida?

Under Florida’s implied consent law (Fla. Stat. §§ 316.1932 and 316.1939), refusing a lawful breath or urine test after a DUI arrest carries both administrative and criminal consequences. Effective October 1, 2025, a first refusal is a second-degree misdemeanor and carries a 1-year administrative license suspension; a second or subsequent refusal is a first-degree misdemeanor and carries an 18-month suspension. Whether refusal is strategically advantageous depends on many facts and should be discussed with counsel — ideally before you ever need the answer.

What happens if I am stopped at a DUI checkpoint?

Florida permits DUI checkpoints subject to strict constitutional and procedural requirements — including advance notice, neutral selection criteria, and a written operational plan. Deviations can support a motion to suppress evidence gathered at the stop.

Will I lose my driver’s license for a first-offense DUI?

A first-offense DUI conviction typically results in a 6-to-12-month license revocation, plus an administrative suspension if challenged unsuccessfully. Hardship licenses may be available in some circumstances after an eligibility period and DUI school.

Can a DUI be expunged or sealed in Florida?

No. Florida statute excludes DUI convictions from eligibility for sealing or expungement. That is a key reason to fight the charge or pursue a negotiated alternative disposition where available.
