How many requirements must be met when using the intoximeter?

• A. 5
• B. 6
• C. 7
• D. 4

Answer: (B)

There are six requirements that must be met when using the intoximeter to ensure a valid reading. The device must be properly calibrated and verified as functioning, following the agency’s schedule and checks. The test must be conducted by a trained officer who follows the approved procedure, so the process is consistent and legally defensible. A mouthpiece must be used correctly—clean, sealed, and free of leaks—to prevent any loss or contamination of breath. The subject must provide a proper end-expiratory breath with sufficient volume, ensuring the sample reflects deep-lung air rather than a shallow puff. There must be no factors that could contaminate the sample, such as residual mouth alcohol or recent ingestion of alcohol or other substances. Finally, the results must be accurately recorded and stored, and a repeat or confirmation test should be performed if the initial result is questionable or requires verification. Because these six elements cover calibration, procedure, sample integrity, contaminant avoidance, documentation, and confirmation, six is the correct number.
