Should You Refuse a Breath Test in Florida?

There is no simple yes or no, and the calculation changed in 2025. As of October 1, 2025, refusing a breath test in Florida is itself a crime, even on a first refusal. Refusing still denies the State a chemical reading, which can make a DUI harder to prove, but it now triggers three separate consequences: an automatic license suspension, a criminal charge, and the ability of prosecutors to use the refusal against you at trial. Understanding this tradeoff before you are ever in that situation is the only way to make a clear-headed decision.

This is one of the most common questions people ask after a DUI arrest, and unfortunately a lot of outdated information circulates about it, including advice that no longer reflects Florida law. Here is how Florida's implied consent law works after the 2025 change, what refusal actually costs, and the factors that matter in a Florida DUI defense.

What Is Florida's Implied Consent Law?

Under Florida's implied consent law, anyone who accepts the privilege of driving in the state is considered to have already agreed to submit to a chemical test of breath, blood, or urine if lawfully arrested for DUI. You gave that consent the day you started driving in Florida, whether you realized it or not.

That is why refusal carries penalties. You are not refusing a random request; you are withdrawing consent you legally already gave, and the law attaches consequences to that.

The 2025 Change: Refusal Is Now a Crime

This is the part most people, and a lot of older online articles, get wrong. Effective October 1, 2025, House Bill 687 amended Florida Statute 316.1939 so that refusing a lawful breath or urine test is a criminal offense even the first time:

• First refusal: a second-degree misdemeanor, punishable by up to 60 days in jail and a fine of up to $500.
• Second or subsequent refusal, or a first refusal by someone whose license was previously suspended for a prior refusal: a first-degree misdemeanor, punishable by up to one year in jail and a fine of up to $1,000.

Before this change, a first refusal carried only an administrative license suspension, not a criminal charge. That is no longer true. For the criminal charge to apply, the arrest must have been lawful and you must have been informed of the consequences of refusing.

What Refusing Actually Costs You

License Suspension

Separate from the new criminal charge, the administrative suspension still applies, and it happens through the DMV regardless of what happens in your criminal case:

• First refusal: one-year driver's license suspension.
• Second or subsequent refusal: 18-month suspension.

You have a limited window (10 days from the arrest) to request a formal review hearing to challenge this administrative suspension. Missing that deadline forfeits the challenge, which is one of many reasons to contact a lawyer immediately. The administrative case and the criminal case are separate; the outcome of one does not control the other.

Use Against You at Trial

Florida prosecutors are allowed to tell the jury that you refused the test and to argue that you refused because you knew you would fail. This is called consciousness of guilt. It is not proof of impairment, and a skilled defense can offer innocent explanations for a refusal, but it is a real disadvantage.

The Other Side: What Refusing Denies the State

The reason this question is not simple is that refusing also takes something away from the prosecution. Without a breath reading, the State has no specific number to put in front of the jury. It must prove impairment through other evidence: the officer's observations, driving pattern, field sobriety performance, and video. For a defendant whose breath result would have been very high, denying the State that number can sometimes make the underlying DUI more defensible.

But the 2025 change weighs heavily on the other side of the scale. Refusing now adds a separate criminal charge of its own, on top of the license suspension and the consciousness-of-guilt argument. That is a genuine strategic tradeoff, and it depends entirely on the specifics. It is also why no responsible lawyer gives a blanket "always refuse" or "always blow" answer.

Do Not Confuse the Breath Test With Field Sobriety Tests

This trips people up constantly. There are two very different things happening during a DUI stop:

• Field sobriety tests are the roadside exercises: the walk-and-turn, the one-leg-stand, and the eye-tracking test. These are voluntary. Declining them does not trigger the implied consent license suspension. They are also highly subjective and frequently challenged.
• The official breath test is the Intoxilyzer test, almost always given at the station after arrest. This is the one governed by implied consent, and refusing it is what carries the automatic suspension.

A roadside portable breath device is generally treated differently from the official station instrument. The distinctions matter, and they are exactly the kind of detail a DUI lawyer examines.

Refusals Can Be Challenged

A refusal is not the end of the story. If the traffic stop was unlawful, if the arrest lacked probable cause, or if the implied consent warning was not properly read, the refusal and its consequences can be challenged and potentially suppressed. And if your case results in a conviction, a reduction to reckless driving may still be possible depending on the overall strength of the evidence.

The Bottom Line

Refusing a breath test in Florida is a real decision with real costs on both sides. It is not a magic escape, and it is not automatically a mistake. If you are facing a DUI, whether you refused or submitted, the specifics of your stop, arrest, and testing determine what defenses are available.
