What is the most likely consequence of failing to properly calibrate the Intoxilyzer 8000?

The most likely consequence of failing to properly calibrate the Intoxilyzer 8000 is that it can produce false blood alcohol concentration (BAC) readings. Calibration is an essential process that ensures the device provides accurate results by aligning its measurements with known standards. When the calibration is off, the device may either underestimate or overestimate a person's BAC, leading to incorrect conclusions about their level of intoxication. This could have serious implications, particularly in legal settings, where the results might influence decisions regarding arrests, penalties, or even license suspensions.

Additionally, while increased lung capacity, reduced testing time, and increased device lifespan might suggest some operational benefits, these are not relevant issues that arise specifically from calibration errors. Proper calibration particularly focuses on the accuracy of the readings, making it fundamental to the device's integrity and function.
