You can refuse a breathalyzer test in Florida, but that refusal isn’t free of consequences. For a lawful breath or urine test requested after a DUI arrest on or after October 1, 2025, a refusal can trigger an administrative driver’s license suspension and a separate criminal charge on top of the underlying DUI allegation.
The word “breathalyzer” is commonly used for a breath alcohol test that measures alcohol concentration after an arrest. The legality of the stop, the arrest, the warning, and the test request can all matter later. Our team has nearly two decades of criminal defense experience and is available 24/7 when you need prompt guidance after an arrest.
What Happens When You Refuse a Breathalyzer in Florida?
A refusal can open two separate tracks: an administrative license suspension through the Florida Department of Highway Safety and Motor Vehicles, and a criminal charge tied to the refusal itself. Both run alongside the underlying DUI allegation.
Under Florida Statutes section 316.1932, Florida’s implied consent law, anyone who drives in the state is considered to have consented to an approved chemical test after a lawful DUI arrest. A refusal carries consequences even if no breath reading is ever obtained.
A First Refusal
For an arrest on or after October 1, 2025, a first refusal to submit to a lawful breath or urine test can be charged as a second-degree misdemeanor and can result in a one-year administrative license suspension.
A Subsequent Refusal
A subsequent refusal can be treated as a first-degree misdemeanor and can lead to an 18-month administrative license suspension. Prior refusal history makes a substantial difference in what’s at stake.
Evidence in the DUI Case
A refusal doesn’t stop the state from pursuing a DUI case. Florida law permits refusal evidence to be introduced in a criminal proceeding, where the prosecution may argue it reflects consciousness of guilt.
How Florida’s Implied Consent Law Actually Works
Implied consent applies to an approved chemical test requested after a lawful DUI arrest, not to every request an officer makes during a roadside stop. Before an arrest, an officer may observe driving behavior, speak with the driver, and request field sobriety exercises, which are physical and cognitive tasks used to assess possible impairment. A portable roadside breath device may also be used in some situations, but it isn’t the same as the post-arrest breath test requested under the implied consent statute.
For implied consent consequences to apply, the request must follow a lawful arrest. Probable cause (facts and circumstances that would lead a reasonable officer to believe a crime occurred) is central to both the arrest analysis and any administrative review. The officer must also provide the required implied consent warning before a refusal-based suspension can be sustained. That warning covers the license consequences of refusal and the possibility that the refusal can be used against you in a criminal case.
How a Refusal Affects Your Driver’s License
An administrative license suspension is entirely separate from the criminal DUI case. Florida Statutes section 322.2615 governs this process, which can begin quickly after a refusal regardless of how the criminal charge is ultimately resolved. You generally have 10 days from the date the notice of suspension is issued to request a formal or informal review with the Florida Department of Highway Safety and Motor Vehicles. Missing that window can eliminate the opportunity to challenge the suspension.
Issues in a review can include:
- Whether the officer had probable cause to believe you were driving or in actual physical control of a vehicle while under the influence
- Whether you were lawfully arrested
- Whether you refused the requested breath or urine test
- Whether the officer gave the required implied consent warning before the alleged refusal
A refusal affidavit (the officer’s sworn report describing the refusal and related events) is typically part of the administrative record. Arrest paperwork, the notice of suspension, video footage, and dispatch records may also be relevant.
Can the State Prove DUI Without a Breath Test?
Yes. The absence of a breath test result doesn’t end a DUI prosecution. Prosecutors can build a case on other evidence gathered during the stop, investigation, and arrest.
That evidence can include:
- Driving conduct, such as lane deviations, speeding, or a collision
- Officer observations of speech, balance, appearance, or odor
- Field sobriety exercise performance
- Statements made during the encounter
- Body camera, dash camera, surveillance, or booking video
- Lawfully obtained blood or urine evidence
- Evidence of the refusal itself
That doesn’t mean each piece of evidence is reliable or admissible. A defense review may examine why the vehicle was stopped, whether the officer followed testing procedures, whether the implied consent warning was correctly given, and how the refusal was documented. Florida’s October 1, 2025 changes, sometimes called Trenton’s Law, make it especially important not to treat refusal as a simple way to avoid a DUI charge.
What to Do After Refusing a Breath Test in Daytona Beach
Start by preserving everything that could matter later. Keep the notice of suspension, citation, bond paperwork, arrest report, towing records, and any documentation related to the breath test request. Write down what you remember about the stop, where it happened, what the officer said, and whether there were witnesses or nearby cameras.
Don’t overlook the 10-day deadline to request an FLHSMV formal or informal review hearing. A formal review is an administrative proceeding that examines the legal grounds for the refusal-based suspension. The criminal DUI case moves through a separate process on its own track.

Why a Refusal Requires a Case-Specific Review
Refusing a breath test isn’t a simple strategy. The consequences depend on the arrest date, prior refusal history, the legality of the arrest and test request, whether the implied consent warning was properly given, and what other evidence exists in the case.
