What is the minimum total volume of breath required for a valid intoxilyzer test?

The minimum total volume of breath required for a valid Intoxilyzer test is indeed 1.1 liters. This volume is essential because the Intoxilyzer 9000 uses this amount to ensure that it captures enough breath sample to accurately measure the blood alcohol concentration (BAC).

A sample this size allows the device to ensure that the readings reflect a more precise representation of the individual’s BAC, which is critical for legal and safety purposes. If the volume is too low, the results may not be reliable or valid, potentially leading to inaccurate readings. This requirement for a minimum volume helps standardize intoxication testing to ensure consistent and fair assessments in enforcement situations.

In contrast, options that suggest lower or higher volumes would not meet the necessary criteria set for the testing procedure, either risking invalid results or compromising the test's reliability.
