Refusing a breathalyzer in Florida triggers severe administrative and criminal penalties under Florida’s Implied Consent Law (Florida Statute § 316.1932). A first-time refusal results in an immediate mandatory one-year driver license suspension. A second or subsequent refusal is classified as a separate First-Degree Misdemeanor crime carrying up to one year in jail.
The Statutory Doctrine of Florida’s Implied Consent Law
When you sign the paperwork to obtain or renew a driver license with the Florida Department of Highway Safety and Motor Vehicles (FLHSMV), you enter into a binding statutory contract with the State of Florida. Operating a motor vehicle on public roads is legally classified as a conditional privilege, not an absolute constitutional right.
Under Florida Statute § 316.1932—widely known as Florida’s Implied Consent Law—any person who accepts the privilege of operating a motor vehicle within the state is deemed by law to have given their implied consent to submit to an approved chemical test of their breath, urine, or blood if they are lawfully arrested for any offense allegedly committed while driving under the influence.
Crucially, Florida’s implied consent statute applies only after a lawful DUI arrest has taken place. Before demanding a breath test, the law enforcement officer must have probable cause to arrest you, place you under formal custody, and read the official Florida Implied Consent Warning from a pre-printed departmental form. Refusing the test after this warning is read triggers immediate state sanctions. The table below delineates the statutory penalties for refusing a chemical breath test in Florida.
| Refusal Frequency & History | Administrative License Sanctions | Criminal Justice Penalties | Hardship License Eligibility |
|---|---|---|---|
| First-Time Breath Test Refusal | Mandatory 12-month driver license suspension | No separate criminal charge (Civil refusal) | Eligible for BAP hardship license after 90 days |
| Second Refusal (Prior Refusal History) | Mandatory 18-month driver license suspension | First-Degree Misdemeanor crime (§ 316.1939) | Strict 18-month hard suspension; zero hardship |
| Third or Subsequent Refusal | Mandatory 18-month driver license suspension | First-Degree Misdemeanor (Up to 1 year jail) | Strict 18-month hard suspension; zero hardship |
| Refusal Involving Serious Injury / Death | Mandatory license suspension + Forced blood draw | Felony DUI charges based on warrant blood draw | Ineligible for driving privileges during pendency |
Roadside Portable Breath Tests (PBT) vs the Intoxilyzer 8000
One of the most widespread sources of legal confusion among Florida motorists is the physical difference between a roadside handheld breath tester and the official desktop breath machine at the police station.
During an active traffic stop on the roadside, a police officer or Florida Highway Patrol (FHP) trooper may ask you to blow into a small, battery-operated handheld gadget called a Preliminary Breath Test (PBT). Under Florida administrative law, PBT handheld devices are NOT approved by the Florida Department of Law Enforcement (FDLE) for evidentiary use in court. You hold the absolute legal right to politely decline the roadside PBT; declining a roadside PBT carries zero license suspension and zero criminal penalties.
Conversely, once an officer places you under formal arrest and transports you to the county jail or DUI Central Breath Testing facility, you are presented with the Intoxilyzer 8000—an FDLE-certified, infrared spectrophotometer. It is the refusal of this certified evidentiary machine—after being read formal implied consent warnings on video—that triggers the mandatory one-year suspension and misdemeanor prosecution. The table below compares the roadside PBT with the station Intoxilyzer 8000.
| Technical & Legal Feature | Roadside Handheld PBT | Station Intoxilyzer 8000 |
|---|---|---|
| Testing Location | Roadside next to vehicle during stop | Secure DUI central testing room at jail |
| FDLE Evidentiary Certification | Not approved; results inadmissible at trial | Certified forensic evidentiary breath machine |
| Legal Obligation to Submit | 100% Voluntary: You can decline freely | Mandatory under Florida Implied Consent law |
| Penalty for Refusal | Zero administrative or criminal penalties | 1-year license suspension; misdemeanor if prior |
| Video Recording Required | Rarely recorded on calibrated instruments | Mandatory 20-minute continuous observation on video |
The Criminalization of Second Refusals: Florida Statute § 316.1939
While a first-time breath test refusal is classified purely as an administrative civil offense handled by the Department of Highway Safety and Motor Vehicles, Florida law takes an exceptionally harsh approach to repeat refusals.
Under Florida Statute § 316.1939, it is a standalone First-Degree Misdemeanor crime to refuse a lawful chemical breath, urine, or blood test if your driving privilege has been previously suspended for refusing a test. This means that if you have a prior refusal on your driving record and you refuse the Intoxilyzer 8000 a second time, you will be hit with two separate criminal charges: Count 1: Driving Under the Influence, and Count 2: Unlawful Refusal to Submit to Chemical Testing.
A conviction under § 316.1939 carries penalties including up to one year in county jail, one year of probation, and a $1,000 criminal fine. Furthermore, the prosecutor in your criminal DUI trial will enter your refusal into evidence under Fla. Stat. § 316.1932(1)(a), arguing to the jury that your refusal demonstrates ‘consciousness of guilt’—insisting that you refused because you knew you were intoxicated.

Final Thoughts & Key Takeaways
Refusing a breathalyzer in Florida carries severe, immediate administrative consequences and can elevate into a separate criminal misdemeanor on a second offense. While declining roadside field sobriety exercises and portable PBT devices is legally permitted without penalty, refusing the official Intoxilyzer 8000 at the station guarantees an automatic one-year license suspension. If arrested, request an immediate administrative formal review hearing within 10 days and retain an experienced Florida DUI defense attorney to challenge the lawfulness of the initial stop.
