What Happens if You Refuse a Breathalyzer in Florida?

KEY TAKEAWAYS:

Refusing a breathalyzer in Florida after a drunk driving arrest can result in driver's license suspension, criminal charges, and additional challenges in a DUI case. Under Florida's implied consent law, a first qualifying refusal can lead to a one-year license suspension and a second-degree misdemeanor charge. A subsequent qualifying refusal can result in an 18-month suspension and a first-degree misdemeanor charge. Prosecutors may also use evidence of your refusal in a DUI case, even without breath alcohol results. You generally have only 10 days to request administrative review of a refusal-related license suspension, making it essential to retain a Fort Lauderdale DUI lawyer promptly.

You're pulled over in Fort Lauderdale after having dinner with friends. The officer suspects you've been drinking and arrests you for DUI. When you're asked to take a breathalyzer test, you hesitate, wondering whether refusing might prevent police from gathering evidence against you. But refusing a breath test after a lawful DUI arrest can lead to serious consequences beyond the penalties for the DUI charge itself.

Under Florida law, refusing a lawful post-arrest breath test can result in driver's license suspension and separate criminal charges. At the Law Offices of Dave L. Simmons, P.A., our Fort Lauderdale DUI defense lawyer can explain your rights, challenge improper testing procedures, and begin defending your case before formal charges are filed. This can help you protect your driving privileges and avoid the harsh consequences you face if you are convicted of DUI.

Can You Legally Refuse a Breathalyzer in Florida?

Florida's implied consent law, as outlined in Florida Statute § 316.1932, drivers are deemed to have consented to an evidentiary breath test if they're lawfully arrested for DUI and an officer has reasonable cause to believe they were driving or in actual physical control of a vehicle while under the influence of alcohol.

If you're charged with DUI, an officer may request an evidentiary breathalyzer test to measure your breath alcohol level. Although you can physically decline the test, refusing doesn't protect you from legal consequences.

It's also important to distinguish between two types of testing:

• Roadside preliminary breath tests. Officers may ask you to take a preliminary breath test before arresting you for DUI. Refusing this test generally doesn't carry the same license suspension and criminal penalties as refusing a lawful evidentiary breathalyzer test after arrest.
• Post-arrest evidentiary breath tests. These tests are administered under Florida's implied consent procedures. Refusing a lawful request can trigger administrative penalties and a separate criminal charge.

The consequences depend on whether the testing request and refusal meet Florida's legal requirements.

Penalties for Refusing a Breathalyzer in Florida

Florida strengthened its breathalyzer refusal laws effective October 1, 2025, under legislation commonly known as Trenton's Law. Previously, a first qualifying refusal generally resulted in an administrative license suspension without a separate criminal refusal charge. Now, even a first qualifying refusal can be prosecuted as a misdemeanor.

Under Florida Statute § 316.1939, potential consequences include:

• First refusal. A qualifying first refusal can result in a one-year driver's license suspension and a second-degree misdemeanor charge, punishable by up to 60 days in jail and a $500 fine.
• Subsequent refusal. A qualifying refusal involving a prior refusal-related suspension can result in an 18-month license suspension and a first-degree misdemeanor charge, punishable by up to 1 year in jail and a $1,000 fine.
• Separate DUI prosecution. Refusing the test doesn't prevent prosecutors from pursuing DUI charges based on other evidence gathered during the investigation.

These are potential statutory penalties, not automatic sentences. The consequences in your case depend on the circumstances, prior history, and applicable law.

Will You Automatically Lose Your License for Refusing a Breath Test?

A qualifying breathalyzer refusal generally triggers an administrative suspension of a driver's license through the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). This process is separate from any criminal charges filed against you.

Under Florida Statute § 322.2615, you generally have 10 days after receiving notice of suspension to request formal or informal administrative review. A formal review provides an opportunity to challenge whether the suspension meets applicable legal requirements.

Depending on your eligibility, you may qualify for temporary or restricted driving privileges while the administrative process proceeds. However, requesting a hearing doesn't automatically restore your license, and hardship driving privileges aren't available to everyone.

Missing the deadline can limit your options for challenging the suspension. Even if the administrative suspension is overturned, any criminal charges must still be addressed separately.

Can You Still Be Convicted of DUI if You Refuse a Breathalyzer?

Yes. Refusing a breath test doesn't prevent a DUI conviction because prosecutors aren't required to produce a breath alcohol reading to establish impairment.

Prosecutors may also rely on these types of evidence, including:

• Driving behavior. Speeding, drifting between lanes, or other observed driving patterns may be presented as evidence of impairment.
• Officer observations. Statements about your speech, balance, appearance, or behavior during the traffic stop may become part of the prosecution's case.
• Field sobriety exercises. Your performance on roadside exercises may be considered alongside other evidence, although the reliability of these exercises can be challenged.
• Video recordings. Dash camera and body camera footage may document your interactions with officers and provide evidence relevant to the allegations.
• Evidence suggesting guilt. Prosecutors may argue that your refusal to take a breath test indicates you believed the results would show impairment. 

A refusal doesn't establish guilt on its own, and the absence of breath test results doesn't guarantee dismissal. Prosecutors must still prove the elements of the charged offense beyond a reasonable doubt.

How to Challenge a Breathalyzer Refusal Charge in Florida

Being accused of refusing a breathalyzer doesn't mean the prosecution can automatically prove its case. Our Fort Lauderdale DUI defense lawyer can examine the circumstances surrounding your arrest and determine whether the evidence supports the allegations.

Potential issues to investigate include:

• Legality of the arrest. Our attorney may challenge whether officers had the required legal grounds to stop you, arrest you for DUI, and request chemical testing.
• Required implied consent warnings. Florida law requires specific warnings about the consequences of refusing a lawful test. Failure to follow applicable requirements may affect the case.
• Evidence of an actual refusal. Police reports, recordings, and witness statements may help establish whether you clearly refused testing or attempted to comply.
• Medical or communication barriers. Physical conditions, language barriers, or other circumstances may be relevant when evaluating whether a refusal occurred.
• Accuracy of breath test results. If you later provided a breath sample and the test produced a reading, our DUI defense attorney may challenge the results by examining the breathalyzer's calibration, maintenance records, testing procedures, and other potential sources of error.

Every DUI investigation involves different facts. The availability and strength of a defense depend on the evidence, testing procedures, and applicable legal standards.

What Should You Do After Refusing a Breathalyzer in Broward County?

If you've already refused a breath test during a DUI investigation, the steps you take within the first 24 hours and the days after your arrest can affect both your driving privileges and criminal case.

Our DUI defense lawyer recommends you take these steps:

• Review your arrest paperwork. Keep copies of your DUI citation, suspension notice, temporary driving permit, and other documents provided by law enforcement.
• Pay attention to the 10-day deadline. Determine whether to request a review of an administrative license suspension before the deadline expires.
• Preserve potential evidence. Save relevant documents and identify witnesses or recordings that may help establish what happened during the traffic stop.
• Follow driving restrictions. Don't assume you can continue driving simply because your criminal case remains pending.
• Understand both legal proceedings. Your administrative license suspension and criminal charges are separate matters that may require different defense strategies.
• Retain an attorney immediately. A Fort Lauderdale DUI defense lawyer can begin protecting your rights immediately and help you meet critical deadlines for contesting your license suspension.

Taking these steps can help you avoid additional legal problems that could weaken your defense as you prepare to address the allegations.
