Can You Defend Against a Failed DUI Breath Test in Fort Lauderdale?
If you’ve been arrested for DUI in Fort Lauderdale or anywhere in South Florida, you may feel like a failed breathalyzer test is the end of the road — but it’s not. That’s because Breath test results can be challenged, and with the right defense strategy, you may be able to reduce or dismiss the charges against you.
⚖️ Understanding Breathalyzer Tests in Florida DUI Cases
When police suspect you of driving under the influence, they may ask you to submit to a breath test. This device measures your blood alcohol content (BAC). In Florida, a BAC of 0.08% or higher is considered over the legal limit.
In Florida, a DUI conviction means you were found guilty of operating a vehicle with a BAC of 0.08% or higher, or while impaired by drugs or alcohol.
Although the law treats breathalyzer results as evidence, a solid criminal defense lawyer can often attach the accuracy of that evidence. Factors like machine error, improper calibration, or operator mistakes may render the results unreliable.
🚨 DUI Arrest Statistics in Florida
According to the Florida Department of Law Enforcement (FDLE), law enforcement made over 29,000 DUI arrests statewide in 2023. In Broward County alone, which includes Fort Lauderdale, police arrested approximately 2,200 DUI suspects, with many involving breathalyzer-based evidence.

❌ Can You Fail a Breath Test and Still Beat the DUI Charge?
Yes. Failing a breath test does not mean an automatic conviction. Your attorney may be able to file a motion to suppress the breathalyzer evidence if the police improperly administered the test or the machine functioned incorrectly.
Common defense strategies include:
- Challenging the accuracy or calibration of the device
- Proving that the officer was not properly trained
- Questioning whether you were actually in physical control of the vehicle
- Showing that certain products (like mouthwash or medication) caused a false reading
- Identifying a software or mechanical error in the breath test machine

🔍 How Breath Tests Can Produce Inaccurate Results
Breathalyzer machines are sensitive and not immune to error. Inaccurate results may come from:
- Software glitches
- Operator error
- Calibration issues
- Contaminants in the mouth (mouthwash, breath spray, etc.)
- Medical conditions (acid reflux, diabetes)
Because of these variables, DUI breath test results are not infallible. An experienced DUI attorney can analyze how the test was conducted and whether it meets legal standards.
