All Georgia DUI cases seem to be similar in one respect — whether or not you were intoxicated. However, in the courtroom, the role of the prosecutor is more specific than that. The state would have to establish a number of elements to convict you, and every element is a potential point of failure. The first step in understanding how DUI cases are actually won or lost is to comprehend what the prosecutor has to prove.
There are two paths for the charge. The “per se” prong of Georgia law is that driving at 0.08 or more of a blood alcohol concentration is illegal regardless of the circumstances. The law also makes it illegal to drive while under the influence of alcohol or drugs to the extent that you are a “less safe” driver — and that prong does not require any particular number. Often, both are charged by prosecutors. Beating the breath test doesn’t automatically dismiss the case, however — the state may argue your driving, your appearance, and the officer’s observations prove you were a less safe driver.
The stop has to be a legal stop first. The prosecutor must demonstrate the legality of the traffic stop before any of the evidence is considered. An officer must have reasonable suspicion of a traffic violation or criminal activity to stop you. If the stop was based on a hunch, a mistake of law, or an anonymous tip without corroboration, the defense can request that the court suppress the officer’s observations, the field sobriety tests, and the chemical test. Many times DUI charges are resolved at the stop without any discussion of breath numbers.
Chemical test must stand up. If the state’s case is based on a breath or blood test, the prosecutor has to prove that the test was administered properly. That includes the proper machine, a valid implied consent advisement, an observation period before the test, and maintenance and calibration logs verifying the machine was in proper working order. Blood tests require a lawful draw — typically a warrant or genuine consent — as well as proper collection, storage, and lab analysis. All of the requirements are a chain, and the defense only has to break one of them.
There is a real standard of “beyond a reasonable doubt.” The prosecutor bears the burden of proving each element beyond a reasonable doubt — the highest burden in our legal system — in a DUI trial. This doesn’t mean proving it with scientific certainty, but it does mean there must be no reasonable doubt in the jurors’ minds. Conflicting officer testimony, a shaky field sobriety test performance with innocent explanations, or a breath result with documented machine issues can each plant the kind of doubt that leads to an acquittal. Jurors take this standard seriously, and good defense lawyers give them concrete reasons to apply it.
That is why it is so important to get an investigation underway early. The evidence the prosecutor needs — the dashcam video, the breath machine’s maintenance logs, the dispatch records — is also the evidence the defense needs to challenge. That material does not improve with age: videos get overwritten, logs get archived, memories fade. The sooner someone starts pulling those threads, the more there is to work with.
If you are facing a DUI charge, talk to an Atlanta DUI Lawyer who approaches the case the way a prosecutor fears: element by element. An Atlanta DUI Attorney will challenge the stop, the tests, and the advisement rather than assuming any of them were done right. A DUI Attorney Atlanta prosecutors know will make the state prove every link in its chain — and a DUI Lawyer Atlanta drivers trust understands that most DUI cases are not won on sympathy, but on the prosecution failing to carry its burden.
The state has the burden. Make them carry it.
