Understanding Florida’s DUI Breath Test Refusal Laws, Penalties, and How a Defense Lawyer Can Protect Your Rights

As a Florida DUI defense lawyer with decades of courtroom experience, I have handled countless cases involving drivers who refused to take a breathalyzer test. Some refused because they feared the results would hurt them, others because they believed they had the right to decline without serious consequences. The reality is that refusing a breath test in Florida is a decision with legal consequences that can affect your driver’s license, your criminal record, and your future.

Florida law treats breath test refusals very seriously. This is due to the state’s “implied consent” law, which essentially states that by driving on Florida roads, you have already agreed to submit to a lawful breath, blood, or urine test when lawfully arrested for DUI.

In this article, I will explain the relevant Florida statutes, what the penalties are for refusing a breath test, how prosecutors use refusals in court, what defenses may apply, and why having a private defense attorney is critical if you are facing a refusal allegation. I will also share an example of a real case I won involving a breath test refusal so you can see how legal strategy plays out in practice.

Florida’s Implied Consent Law

Florida Statute § 316.1932(1)(a)1.a states:

“Any person who accepts the privilege extended by the laws of this state of operating a motor vehicle within this state is, by operating such vehicle, deemed to have given his or her consent to submit to an approved chemical test or physical test including, but not limited to, an infrared light test of his or her breath for the purpose of determining the alcoholic content of his or her blood or breath if the person is lawfully arrested for any offense allegedly committed while the person was driving or was in actual physical control of a motor vehicle while under the influence of alcoholic beverages, chemical substances, or controlled substances.”

This means that the moment you operate a vehicle in Florida, you are legally considered to have agreed to testing under certain conditions. However, while the law says you have consented, you can still refuse. The refusal simply triggers certain penalties.

Consequences of a First Refusal

Under Florida Statute § 316.1932(1)(a)1.a and § 322.2615, a first refusal to submit to a breath test results in:

  • An automatic one-year driver’s license suspension administered by the Florida Department of Highway Safety and Motor Vehicles (DHSMV), regardless of whether you are later convicted of DUI.

  • The refusal can be used as evidence against you in court to suggest “consciousness of guilt.”

Importantly, this suspension is administrative, meaning it happens outside the criminal court system. You only have 10 days from the date of your arrest to request a formal review hearing to challenge the suspension. Without action, you lose your license automatically after the temporary permit expires.

This is where having a private attorney is critical. I routinely represent clients at these DHSMV hearings, often winning reinstatement of driving privileges by exposing weaknesses in the state’s case, such as an unlawful stop, improper breath test request procedures, or the officer’s failure to properly read the implied consent warning.

Consequences of a Second or Subsequent Refusal

A second or subsequent refusal carries far more severe consequences. Florida Statute § 316.1939 makes it a first-degree misdemeanor to refuse a breath test if you have previously refused. The statute reads:

“A person who has refused to submit to a lawful test of his or her breath, urine, or blood, and whose driving privilege has been previously suspended for a prior refusal to submit to a lawful test of his or her breath, urine, or blood, and who is again arrested for a violation of s. 316.193, commits a misdemeanor of the first degree…”

A first-degree misdemeanor in Florida is punishable by up to:

  • 12 months in jail

  • 12 months of probation

  • A $1,000 fine

Additionally, a second refusal results in an 18-month driver’s license suspension with no eligibility for a hardship license. This can be devastating for anyone who depends on driving for work or family obligations.

Defenses to a Breath Test Refusal

Even though the law is strict, refusing a breath test does not automatically mean you will be convicted or lose your license. I have successfully defended many refusal cases using strategies such as:

  • Challenging the lawfulness of the traffic stop – If the officer lacked reasonable suspicion or probable cause to stop you, all evidence, including the refusal, can be suppressed.

  • Proving improper implied consent warnings – Florida law requires the officer to read the implied consent warning in a very specific way. If they fail to do so, the refusal may be inadmissible.

  • Medical or language barriers – In some cases, my clients did not understand the request due to medical conditions, hearing loss, or language issues.

  • Officer credibility issues – Cross-examining the arresting officer can reveal inconsistencies in the arrest report or testimony that cast doubt on the state’s case.

Without a lawyer who understands how to spot these issues, many people end up pleading guilty or accepting the penalties without realizing they had a strong defense.

How Refusals are Used in Court

Prosecutors love to use refusals as evidence. They argue that you refused because you knew you were intoxicated. This is known as “consciousness of guilt” evidence. However, in trial, I work hard to dismantle that narrative by showing the jury alternative explanations, such as distrust of faulty machines, fear of needles in blood draws, or prior bad experiences with law enforcement.

Having a private attorney matters here because public defenders, while often skilled, are frequently overburdened and may not have the time to conduct the same level of investigation into the officer’s training records, the breath machine’s maintenance logs, or bodycam footage.

Real Case Example – DUI Refusal Dismissed

One of my clients, a 42-year-old man from Tampa, was stopped late at night for allegedly swerving within his lane. The officer claimed he smelled alcohol and asked my client to perform roadside exercises, which he declined. The officer then requested a breath test, and my client refused. He was arrested and charged with DUI refusal, facing a one-year suspension and a criminal conviction.

When I reviewed the evidence, I discovered two critical problems. First, the dashcam video showed my client driving straight without swerving. Second, the officer misread the implied consent warning, skipping a key sentence about the consequences of refusal.

I filed a motion to suppress the refusal based on an unlawful stop and improper warning. The judge agreed, ruling that the stop was unsupported by reasonable suspicion and that the state could not use the refusal as evidence. The DUI case was dismissed entirely, and my client’s license was reinstated.

Why You Need a Private DUI Defense Attorney

Every section of this issue, from the traffic stop to the officer’s wording of the implied consent warning, can make or break your case. A private attorney has the time and resources to investigate every angle. That means subpoenaing dashcam footage, examining the calibration logs for the breath machine, and questioning every step the officer took.

Refusal cases are winnable. The law is technical, and the state must follow strict procedures. If they fail at any point, an experienced defense attorney can exploit those mistakes to protect your rights, your license, and your future.
