When you face an OWI charge in Indiana, the charges often weigh heavily on the blood alcohol concentration measured by a breathalyzer or blood draw. However, that number reflects your status at the time of the test, not necessarily while you were behind the wheel. Understanding the rising BAC argument can be helpful in assessing possible defenses.
Timing shifts the legal landscape
Chemical tests usually happen much later at a police station or hospital. This gap in time creates a window where your body continues to process what you drank, potentially pushing your BAC over the legal limit of 0.08% (for most drivers) after you stopped driving.
The rising BAC defense hinges on the science of alcohol absorption. After your last drink, your body takes time to move alcohol into your bloodstream. If police pulled you over shortly after drinking, your BAC might have been below the limit while driving but peaked during the subsequent chemical test. Several factors influence whether this strategy fits a specific case:
- The exact time of your last drink compared to the stop
- Whether you consumed food, which slows absorption
- The time between the traffic stop and the official test
- Results of a preliminary roadside breath test (PBT), if taken
Attorneys often look for a significant delay between the driving event and the testing phase to support this argument.
Limits to the rising alcohol argument
This defense is not a universal solution for every DUI or OWI charge. Indiana courts and prosecutors scrutinize the timeline closely. If several hours passed between your last drink and the time police stopped you, your body likely already reached its peak BAC. In these instances, your levels could be falling, not rising, which negates the primary premise of this defense.
Additionally, prosecutors may still rely on other evidence like driving behavior, field sobriety tests and officer observations to argue you were impaired, even if your BAC may have been increasing between the stop and the chemical test.
Seeking clarity in complex OWI cases
Public discussions often oversimplify or misunderstand drunk driving defenses, but the reality can involve complex elements, specific details of an arrest and legal interpretations. An attorney can evaluate these variables alongside the police report to determine the most appropriate way forward.
