Under what condition should the results of the chemical test be included in the officer's testimony?

The appropriate condition for including the results of a chemical test in an officer's testimony is that the officer must have been the one administering the test. This ensures that the officer can provide firsthand knowledge about the conduct of the test and its adherence to proper procedures. When the testing officer testifies, they can explain the context of the results, including how the sample was collected, the type of test administered, and how the results correspond to the signs of impairment observed in the field.

While consent from the driver to undergo testing is a critical aspect of the legality of the test itself, it alone does not qualify the results for inclusion in testimony unless the officer who performed the test is the same one providing the testimony. Similarly, having unobstructed evidence or the availability of test results might be favorable factors, but they do not inherently validate the credibility of the results in the absence of testimony from the administering officer. Thus, the focus on the officer’s role in administering the test is paramount.
