Georgia Breathalyzer Lawyer
The attorneys at The Spizman Firm have spent years handling DUI cases across Georgia, and one pattern emerges consistently: the breathalyzer result is often treated as the end of the story when it is, in fact, just the beginning of a much more complicated evidentiary question. A Georgia breathalyzer lawyer knows that breath test machines are not infallible instruments of truth. They are mechanical devices maintained by human beings, calibrated on schedules that are not always followed, and operated under conditions that directly affect their accuracy. Before accepting a breath test result as valid proof of impairment, there is a significant amount of ground to cover.
How Georgia Law Treats Breath Test Evidence in DUI Prosecutions
Georgia’s DUI statute, codified under O.C.G.A. § 40-6-391, defines driving under the influence in two distinct ways. A driver can be charged for being in an “actual physical control” of a vehicle while impaired to the extent that it is less safe to drive, regardless of a specific alcohol concentration reading. Separately, a driver can be charged for having a blood alcohol concentration (BAC) of 0.08 grams or more per 210 liters of breath at the time of driving. These are often filed together, and that distinction matters enormously for how a defense is built.
When a breath test reading comes in at exactly 0.08, the case looks very different than one involving a 0.16 or a 0.23. The prosecution’s approach, the likelihood of a plea offer, and the viability of challenging the test all shift depending on where the number lands. Georgia also applies a lower threshold of 0.04 for commercial drivers and a zero-tolerance standard for drivers under 21 under O.C.G.A. § 40-6-391(k), meaning the category of the driver changes what the prosecution has to prove and what penalties attach.
One element that often surprises people: Georgia follows an implied consent law under O.C.G.A. § 40-5-55, which means that by operating a vehicle on a Georgia road, a driver has already legally consented to chemical testing if lawfully arrested for DUI. Refusing a breath test triggers an automatic one-year license suspension for a first offense, independent of any criminal conviction. That refusal can also be introduced at trial as consciousness of guilt. The decision to refuse or submit has consequences either way, and it is a decision that typically happens before any attorney is present.
What Weakens a Breath Test Result in Court
The Intoxilyzer 9000 is the instrument used by Georgia law enforcement agencies, including the Georgia State Patrol, for evidentiary breath testing. It was introduced to replace the older Intoxilyzer 5000EN, and it has faced its own rounds of legal challenge. Machines must be maintained according to the Georgia Bureau of Investigation’s Division of Forensic Sciences protocols, and any departure from those protocols opens the door to a challenge. Officers are required to observe a driver for a minimum of 20 minutes prior to administering the test to rule out belching, vomiting, or oral alcohol that could contaminate the reading. That 20-minute observation window is not always properly documented or adhered to.
Certain medical conditions and physiological factors can also skew results. Individuals with acid reflux or GERD can experience mouth alcohol contamination that inflates a reading. Diabetics in ketosis may produce isopropanol that some devices misread as ethanol. High body temperature raises breath alcohol readings. These are not speculative defenses invented by attorneys. They are well-documented in forensic literature and have been the basis for suppression motions and acquittals in Georgia courts. The firm’s DUI results, including not-guilty verdicts in cases involving breath readings of 0.18 and 0.23, reflect what happens when these issues are examined thoroughly rather than accepted at face value.
Beyond the science, there is a procedural dimension. Georgia courts have held that an unlawful stop renders all evidence obtained from it inadmissible under the fruit of the poisonous tree doctrine. If the officer lacked reasonable articulable suspicion to initiate the traffic stop, the breath test result and everything else that followed can be suppressed. This is why the legality of the stop itself is one of the first things examined in any DUI defense, not an afterthought.
Penalties That Follow a Georgia DUI Conviction and Why Classification Matters
A first DUI conviction in Georgia carries mandatory minimum penalties under O.C.G.A. § 40-6-391(c): a fine of $300 to $1,000, 24 hours to 12 months in jail with credit given for time served, a minimum of 12 months probation, 40 hours of community service, completion of DUI Alcohol Risk Reduction Program, and a clinical evaluation. The sentencing structure escalates sharply with each subsequent conviction within a ten-year lookback period. A second DUI within ten years requires a minimum of 72 hours in jail and mandatory publication of the offender’s name and photo in the county organ. A third DUI within ten years is classified as a high and aggravated misdemeanor.
A fourth DUI within ten years, however, is classified as a felony under Georgia law, which permanently alters the nature of the case and the collateral consequences that follow. Felony DUI convictions carry the potential for imprisonment in a state correctional facility, loss of certain civil rights, and a criminal record that affects professional licensing, housing applications, and federal employment eligibility in ways that a misdemeanor conviction does not. For lawyers, doctors, nurses, teachers, and other licensed professionals, even a first misdemeanor DUI can trigger licensing board inquiries and disciplinary proceedings.
The aggravated DUI classification under O.C.G.A. § 40-6-391(l) applies when a driver is convicted of DUI with a BAC of 0.15 or higher. This designation requires the installation of an ignition interlock device and impacts the terms of any limited permit. That single threshold, 0.15, draws a meaningful legal line that affects how the case is resolved and what restrictions follow a conviction. Understanding where a client’s case falls relative to these markers shapes every stage of the defense strategy.
The Administrative License Suspension Process Runs Parallel to the Criminal Case
Most people are unaware that a DUI arrest in Georgia triggers two separate proceedings simultaneously. The criminal case moves through the court system. The administrative license suspension runs through the Georgia Department of Driver Services and operates on its own timeline. A driver who submits to a breath test and registers 0.08 or higher, or who refuses testing, has just 30 days from the date of arrest to request an administrative license suspension hearing or install an ignition interlock device under Georgia’s current framework. Missing that window forfeits the right to contest the suspension.
This 30-day deadline runs from the moment of arrest, which often means it begins ticking while a person is still processing what happened and before they have consulted anyone. The administrative hearing is a separate opportunity to challenge the legality of the stop and the test, and it can produce findings that are useful in the criminal case as well. Getting ahead of this deadline is not merely procedural housekeeping. It determines whether someone can drive legally while their criminal case resolves, which can take months.
Common Questions About Challenging Breathalyzer Results in Georgia
Can a breathalyzer result be thrown out entirely?
Yes, under certain circumstances. Georgia courts can suppress breath test results if the arresting officer lacked probable cause, if the implied consent warning was not properly administered, if the 20-minute observation period was not followed, or if the Intoxilyzer 9000 was not properly calibrated and maintained per GBI protocols. When a result is suppressed, the prosecution must rely solely on other observations, like field sobriety test performance and officer testimony, which typically weakens the case significantly.
What happens if I refused the breath test?
Refusal triggers an automatic license suspension under O.C.G.A. § 40-5-55: one year for a first offense, three years for a second within five years. The refusal itself can be presented to a jury as circumstantial evidence of guilt. However, the prosecution must still prove impairment through other evidence, and cases built entirely on officer observations without chemical test results have their own vulnerabilities.
Does a high BAC reading make a not-guilty verdict impossible?
Not at all. The Spizman Firm has secured not-guilty verdicts in cases involving breath test readings of 0.18 and 0.23. The validity of the test, the conditions under which it was administered, the defendant’s medical history, and the lawfulness of the stop all remain live issues regardless of the number on the printout.
Is DUI always a misdemeanor in Georgia?
Most first, second, and third DUI offenses are misdemeanors, though a third conviction within ten years is a high and aggravated misdemeanor with enhanced sentencing. A fourth conviction within ten years is charged as a felony under O.C.G.A. § 40-6-391(c)(5). Certain circumstances, such as DUI causing serious injury or death under O.C.G.A. § 40-6-394, elevate the charge to a felony regardless of prior record.
How long does a DUI stay on my record in Georgia?
In Georgia, DUI convictions are not eligible for expungement. The conviction remains on the criminal history permanently. For purposes of sentencing enhancements, prior DUI convictions are counted within a ten-year lookback period, but the conviction itself does not disappear from background checks after ten years. This is one reason why fighting the charge from the start carries more long-term value than most people initially recognize.
What is the implied consent warning and what happens if it is not given?
Georgia law requires officers to read the implied consent notice before requesting a chemical test. There are different versions for different situations, including one for suspects under 21 and one for commercial drivers. Failure to give the appropriate warning, or giving it in a manner that is misleading or incomprehensible, can be grounds to exclude the test result. Courts have considered factors including whether the warning was read clearly and whether the driver had an opportunity to make an informed decision.

Speak With a Georgia DUI Defense Attorney About Your Breath Test Case
The most common reason people hesitate to call an attorney after a DUI arrest is the assumption that the breath test result makes the outcome a foregone conclusion. It does not.

The firm offers a free case review so that anyone who has been arrested can understand exactly what the evidence shows, where it may be vulnerable, and what realistic outcomes look like before deciding how to proceed. For anyone facing a breathalyzer-related DUI charge in Georgia, having an attorney who is familiar with the courts, the science, and the procedural requirements of these cases is what separates a thorough defense from simply accepting whatever the prosecution offers.
