Florida’s DUI Blood Test Laws Explained
Under Florida Statutes §316.1932, every person who operates a vehicle in the state is subject to the implied consent law. This law means that by driving on Florida roads, you are deemed to have consented to submit to an approved chemical test—such as a breath, urine, or blood test—if lawfully arrested for DUI.
However, there are limits. Law enforcement cannot automatically force a blood test. Instead, the law sets strict conditions for when a blood draw may be authorized.
A blood test is generally permitted in the following situations:
- When a driver voluntarily consents after being informed of their rights.
- When a breath or urine test is impossible or impractical, such as after a crash that results in serious injury or death.
- When a warrant is obtained from a judge authorizing the test.
Outside of these situations, forcibly drawing blood from a suspect without legal justification violates constitutional protections against unreasonable searches and seizures under both the Fourth Amendment to the U.S. Constitution and Article I, Section 12 of the Florida Constitution.
When Can Police Use Force to Obtain a Blood Sample?
Florida Statute §316.1933(1)(a) is the key authority on forced blood draws. It allows an officer to require a blood test—without consent—if they have probable cause to believe a motor vehicle crash caused death or serious bodily injury and that the person driving under the influence contributed to the accident.
This means that outside of serious injury or fatal collisions, law enforcement typically cannot physically compel you to give a blood sample. In most DUI stops that do not involve an accident, the officer must rely on a breath or urine test unless a warrant is issued.
Even in cases where a warrant is sought, the process must follow strict procedures. A judge must review a sworn affidavit from the officer establishing probable cause. Any deviation—such as an invalid warrant or improper execution—can render the blood test evidence inadmissible in court.
Florida’s Warrant Requirement After Missouri v. McNeely
The U.S. Supreme Court’s landmark decision in Missouri v. McNeely (2013) changed how states, including Florida, handle blood tests in DUI investigations. The Court ruled that the natural dissipation of alcohol in the bloodstream does not automatically justify a warrantless blood draw. Instead, each situation must be evaluated under the “totality of the circumstances.”
In other words, unless there is a true emergency that makes obtaining a warrant impossible, police must secure judicial authorization before performing a forced blood test. Florida courts have followed this precedent closely, requiring officers to justify any claim of “exigent circumstances.”
The Role of Probable Cause in Blood Test Requests
To lawfully request a blood sample, police must first establish probable cause that you were driving under the influence. This may include evidence such as:
- Erratic driving behavior or involvement in a crash.
- The odor of alcohol, slurred speech, or unsteady movements.
- Results from field sobriety exercises.
- Statements made by the driver.
However, these indicators alone are not always reliable. Officers sometimes misinterpret fatigue, medical conditions, or environmental factors as signs of impairment. That’s why it’s critical to have an experienced DUI Attorney in Orlandoreview every step of the investigation, from the initial stop to the administration of any test.
What Happens If You Refuse a Blood Test
Refusing a lawful test under the implied consent law carries significant penalties in Florida. According to §316.1939, a first refusal can lead to a one-year driver’s license suspension, and a second refusal can result in an 18-month suspension plus a separate misdemeanor charge.
But not every refusal is illegal. If the request for a blood test was not legally justified—such as when no warrant was obtained, or there was no serious injury or death—then your refusal should not trigger a suspension or criminal penalty.
I frequently challenge refusals by showing that the officer lacked authority to demand a blood test in the first place. If the police failed to comply with the statute, I fight to have the evidence excluded and the suspension overturned.
Medical Privacy and Chain of Custody Issues
Blood tests raise additional privacy concerns. Drawing blood is an invasive act that requires proper medical training, sterile equipment, and strict adherence to chain-of-custody procedures. Florida law mandates that blood be drawn by authorized personnel—such as a nurse, physician, or certified paramedic—using approved medical protocols.
If the sample is mishandled, mislabeled, or contaminated, the test results can be challenged and potentially thrown out. I review every stage of the collection and testing process, including lab documentation and technician credentials, to uncover errors that may cast doubt on the validity of the results.
Common Defense Strategies in Blood Test DUI Cases
Each case is unique, but as an Orlando DUI Defense Lawyer, I employ several proven defense approaches depending on the circumstances:
1. Illegal Search or Seizure: If the blood draw occurred without consent, a valid warrant, or statutory authority under §316.1933, I move to suppress the evidence as unconstitutional.
2. Faulty Warrant: Warrants must be based on reliable information. Any factual errors or lack of probable cause can invalidate the entire test.
3. Contamination or Improper Handling: Laboratory and storage errors are more common than most people realize. Small mistakes in labeling or refrigeration can distort results.
4. Chain of Custody Breaks: If the state cannot document every person who handled the sample, the evidence’s integrity collapses.
5. Rising BAC Defense: Alcohol levels change over time. By showing that your BAC was below the legal limit while driving, even if it rose later during testing, I can weaken the prosecution’s case.
6. Medical or Dietary Conditions: Certain health issues and medications can mimic signs of impairment or interfere with test readings.
The Consequences of a DUI Blood Test Conviction
If the prosecution successfully introduces blood test results showing a blood-alcohol concentration (BAC) of 0.08% or higher, you could face severe penalties under §316.193(2):
- Fines between $500 and $1,000 for a first offense.
- Up to six months in jail.
- Mandatory probation and community service.
- Driver’s license suspension.
- Ignition interlock device installation.
For repeat offenses, penalties increase dramatically, including felony charges, multi-year license revocations, and permanent criminal records. Beyond the legal consequences, a DUI conviction can damage employment prospects, insurance rates, and professional reputation.

Case Example: Suppression of an Unlawful Blood Test
A recent client was involved in a minor crash in Orange County. The officer claimed the driver appeared intoxicated and ordered a blood draw at the hospital without obtaining a warrant. The driver never gave consent, and no serious injuries occurred.
I filed a motion to suppress the blood test results, arguing the officer lacked legal authority under §316.1933 and violated Missouri v. McNeely. The court agreed that the circumstances did not justify a forced draw. Once the blood evidence was excluded, the prosecution dismissed the DUI charge.
This case highlights how crucial it is to have an Orlando DUI Defense Lawyer who understands both the science and the law behind forced blood tests.
Protecting Your Constitutional Rights
Blood tests are among the most invasive forms of evidence collection in DUI investigations. Without proper legal safeguards, your constitutional rights can easily be violated. If you were forced to submit to a blood test or arrested after refusing one, I can review whether your rights were infringed and take immediate steps to challenge the results.
I often uncover procedural and constitutional errors that lead to reduced charges, dismissed cases, or acquittals. These defenses are not hypothetical—they are built on real violations that happen every day in Florida DUI investigations.
Orlando DUI Defense Frequently Asked Questions
Can Orlando police draw my blood without a warrant?
Only under very limited conditions. Florida law allows a warrantless blood draw if there’s probable cause to believe you caused serious injury or death in a crash while under the influence. Outside of that scenario, officers must obtain a valid warrant or your voluntary consent. If they skip this step, any evidence collected may be excluded from court.
What if I refuse to give blood when asked?
You have the right to refuse in most cases unless the officer has statutory authority under §316.1933 or a signed warrant. However, refusal can lead to administrative penalties such as license suspension. A skilled DUI Attorney in Orlando can determine whether your refusal was justified and fight to restore your driving privileges.
Are hospital blood tests admissible in DUI cases?
Sometimes hospitals draw blood for medical purposes after a crash. Law enforcement must follow specific procedures before accessing these results. If the state obtained your hospital records without a warrant or subpoena, those results can often be suppressed.
How accurate are DUI blood tests?
Blood tests are not infallible. Issues such as sample contamination, equipment calibration, or incorrect storage temperatures can lead to false readings. I frequently consult independent toxicologists to review the state’s lab results and identify scientific weaknesses.
Can I be charged with DUI based solely on a blood test?
Yes, but the prosecution must first prove that the test was obtained lawfully and processed correctly. Without proper chain-of-custody documentation and a valid warrant or consent, the results are unlikely to stand in court.
What’s the difference between a breath test and a blood test?
A breath test measures alcohol concentration through exhaled air, while a blood test measures it directly from the bloodstream. Blood tests can also detect drugs. However, because they’re more invasive, the law restricts when police can require them.
How long does the state have to file DUI charges after a blood test?
Florida prosecutors typically wait for lab results before filing formal charges, which can take weeks or months. However, the statute of limitations still applies. If delays occur or evidence is mishandled, I can seek dismissal for lack of timely prosecution.
What should I do if I’m asked to take a blood test after an accident?
Politely ask whether the officer has a warrant. If they do not, you have the right to refuse unless there’s a serious injury or fatality involved. Remain calm, avoid arguing, and contact an attorney immediately.
Can I challenge my driver’s license suspension after refusing a blood test?
Yes. You can request a formal review hearing with the Florida Department of Highway Safety and Motor Vehicles (DHSMV) within ten days of your arrest. As your attorney, I can represent you at this hearing to contest the suspension and expose flaws in the officer’s procedure.
Will a forced blood draw affect my chances in court?
It can, but forced blood draws are often legally vulnerable. If the officer exceeded statutory authority or failed to obtain a proper warrant, I can move to exclude the blood evidence. Without that evidence, the prosecution’s case often collapses.
