What technical issues might lead to a wrongful DUI conviction based on Intoxilyzer 9000 data?

Calibration errors or environmental interferences are critical factors that can compromise the accuracy of results from the Intoxilyzer 9000, potentially leading to wrongful DUI convictions. The Intoxilyzer relies on a series of precise measurements to assess blood alcohol concentration (BAC) and any deviations in calibration may yield erroneous readings. For example, if the device is not correctly calibrated to the standards set by regulatory authorities, it might interpret the presence of alcohol inaccurately, showing a higher or lower BAC than actually present.

Environmental interferences, such as the presence of certain chemicals or substances in the air, can also impact the readings. For instance, fumes from cleaning products or even certain food items consumed shortly before the test might influence the device's measurements, leading to a false impression of intoxication. Therefore, ensuring that the Intoxilyzer 9000 is both properly calibrated and free from environmental interferences is essential for accurate testing and protecting individuals from wrongful convictions based on flawed data.
