Being charged with Driving Under the Influence of Alcohol or Drugs (DUI) can negatively impact a person’s driving record for decades. The main method of determining whether a DUI is valid is the breathalyzer test administered by the officer on the scene. These tests can be damning, but they can also be wrong.
There are three major issues that can arise with a field-administered breathalyzer test that may cause it to give a blood alcohol content (BAC) reading that is higher than the individual’s actual blood levels. These issues are calibration, timing, and rising windows.
Breathalyzers are sophisticated machines. As such, they require the maintenance of a technician to ensure that they are properly calibrated. An incorrectly calibrated breathalyzer can cast doubt on the accuracy of the BAC reading the device provides. A breathalyzer must generally be recalibrated once every 10 days or after 150 uses to remain accurate.
The timing of when the officer administers the breathalyzer can also impact the readings it gives. As the name implies, a breathalyzer is meant to examine the amount of alcohol on the breath. This breath comes from deep in the lungs to be as accurate as possible. However, if the individual has recently drunk alcohol, burped, or vomited, there may be residual alcohol left in the mouth that will give a far higher BAC reading than is accurate.
Officers are supposed to wait at least 15 minutes after the individual did any of these actions before administering a test. Additionally, if the individual burps or vomits again in the officer’s presence, the count must be restarted. Failing to observe these rules can result in an inaccurate reading.
Finally, there is something known as the rising window. Most individuals who drink alcohol take one to three hours to fully absorb it into their systems. During this time, their BAC will increase steadily despite them not drinking any more alcohol. If a breathalyzer test is administered during these windows, the BAC will be inflated even if the individual’s behavior is unaffected.
If you have been charged with a DUI, you will need an experienced DUI attorney to help you combat the charges. A DUI attorney can challenge the results of your breathalyzer test by identifying errors in administration or providing alternate explanations for the high BAC reading.
Additionally, a DUI attorney can cross-examine the administering officer to determine whether or not they are exaggerating or misrepresenting the threat you allegedly demonstrated. The best place to find a DUI attorney is Attorney at Law.
