In addition to maintaining equipment, what must operators ensure regarding testing procedures?

Operators must adhere strictly to established protocols and guidelines to ensure the accuracy and reliability of the testing procedures. This adherence is crucial for several reasons. Firstly, standardized protocols are designed to minimize errors and ensure consistency in testing, which is essential for obtaining valid results in assessing a subject's BAC (blood alcohol concentration). Following these guidelines helps to uphold the integrity of the testing process and the credibility of the results in legal contexts.

Moreover, compliance with established protocols is necessary to meet regulatory requirements and maintain certification. If operators deviate from these procedures, the validity of the test results could be challenged in court, potentially impacting the outcomes of DUI cases. Therefore, strict adherence not only supports the operational efficacy of the equipment but also safeguards the legal and ethical responsibilities of the operators.
