Orlando Breathalyzer Defense Lawyer — Challenge the Test
A failed breath test feels like the end of the road — but it's not. Florida's Intoxilyzer 8000 depends on strict calibration, maintenance, and operator procedure, and any breakdown can make your reading unreliable and inadmissible. Our breathalyzer defense attorneys know exactly where these machines fail. Call (407) 777-8888 for a free, confidential case evaluation.

Why a Breath Test Can Be Challenged
Prosecutors treat a breathalyzer reading as ironclad proof of guilt. It isn't. The Intoxilyzer 8000 — the only breath-test instrument approved for evidential use in Florida — is a complex device that only produces reliable results when it's properly maintained, calibrated on schedule, and operated exactly according to protocol. When any link in that chain breaks, the number it prints is no longer trustworthy.
Beyond the machine itself, human biology and procedure create even more room for error. A mandatory 20-minute observation period is routinely rushed or interrupted. Mouth alcohol from acid reflux, burping, or dental work can spike a reading. Diabetes and low-carb diets can trick the sensor. And because alcohol keeps absorbing after your last drink, your true BAC behind the wheel may have been lower than what the machine measured later at the station.
At ANT Law Firm, our Orlando DUI defense attorneys treat the breath test as the state's central — and most attackable — piece of evidence. We subpoena the machine's complete history, verify every certification, dissect the testing procedure, and when the facts support it, move to suppress the result entirely. Discredit the breath test, and the entire case against you can fall apart.

A breath-test challenge is one piece of a complete DUI defense. Explore how our Orlando DUI attorneys handle related charges and issues.
Field Sobriety Tests
Roadside exercises are often used to justify a breath test. We challenge how they were administered and scored.
Commercial Driver DUI
CDL holders face a .04 BAC limit, so an unreliable breath result can end a career. Accuracy matters even more.
Underage DUI
With a .02 zero-tolerance limit for drivers under 21, even a small breath-test error can trigger a suspension.
How Breath Test Results Go Wrong
The Intoxilyzer 8000 can be wrong in more ways than most people realize. Each of these failure points is a potential path to suppressing or discrediting your breath result.
Calibration and maintenance failures
The Intoxilyzer 8000 must be calibrated and inspected on a strict schedule. Missed inspections, failed calibration checks, or out-of-tolerance results can make readings inadmissible.
Operator error and certification
Only certified operators can lawfully administer the test, and they must follow a mandatory 20-minute observation period. Errors in procedure or lapsed certifications undermine the result.
Mouth alcohol contamination
GERD, acid reflux, burping, dental work, or residual mouth alcohol can trap alcohol in the mouth and produce a falsely high reading that doesn't reflect blood-alcohol content.
Rising blood alcohol
Alcohol takes time to absorb. Your BAC may have still been rising after you stopped driving, meaning it was actually lower behind the wheel than when the machine measured it.
Medical and dietary factors
Diabetes, ketosis, low-carb diets, and certain medical conditions can produce acetone and compounds that some breath machines misread as alcohol.
Radio frequency and software issues
Electronic interference, software glitches, and unresolved error codes in the source code of the Intoxilyzer 8000 have all been used to challenge the reliability of Florida breath results.
Refused the Test? You Still Have 10 Days
Whether you took or refused the breath test, you have only 10 daysafter a DUI arrest to request a DHSMV formal review hearing and fight your license suspension. Don't lose your license by default — call our Orlando DUI attorneys right away.
How Our Attorneys Attack a Breath Test
From records requests to motions to suppress, here's how our Orlando DUI lawyers dismantle the state's breath-test evidence.
Free Case Evaluation
Call or submit our form. We review the breath test, the stop, and the reports, then explain how we can challenge the result — free and confidential.
Records Request
We immediately subpoena the maintenance logs, calibration records, and operator certifications for the exact Intoxilyzer machine used in your arrest.
Technical Review
We analyze the machine's history, the observation period, and the testing procedure for the errors and deviations that make breath results unreliable.
Motions to Suppress
Where the evidence supports it, we move to exclude the breath result entirely — often the strongest evidence the state has against you.
Negotiation or Trial
With the breath result weakened or excluded, we push for a dismissal, a reduction to reckless driving, or take the case to trial.
How We Fight Breath Test Evidence
The breath test is usually the prosecution's strongest evidence — which means beating it can change your entire case. Our DUI defense lawyers use every scientific and procedural tool available under Florida law to challenge that reading.
Subpoenaing maintenance and calibration records
We demand the full maintenance history, calibration logs, and inspection records for the specific machine used — gaps and failures here can invalidate your result.
Challenging the 20-minute observation
Florida requires an uninterrupted 20-minute observation before the test. If the officer looked away, left, or you burped, the result may be thrown out.
Attacking operator certification
We verify the breath-test operator and agency inspector held valid, current certifications. Lapsed or improper credentials can render the test inadmissible.
Exposing mouth alcohol and medical causes
We present evidence of GERD, reflux, dental conditions, or diets that create falsely elevated readings unrelated to actual impairment.
Rising BAC and absorption defense
Using the timeline of your drinking and driving, we show your BAC may have been under the legal limit while you were actually operating the vehicle.
Challenging implied consent and refusals
If you refused, we examine whether the implied-consent warnings were properly given. Defects in the warning can affect the admissibility of a refusal at trial.
A Failed Breath Test Is Not the Final Word.
