What is a requirement under O.C.G.A. 40-6-392 regarding testing instruments?

The requirement that testing instruments must be checked for calibration quarterly under O.C.G.A. 40-6-392 is essential to ensure the accuracy and reliability of test results. Calibration is the process of verifying that the instrument is providing accurate readings. By checking the calibration quarterly, law enforcement ensures that the instruments used for measuring a person's blood alcohol content are functioning correctly and are capable of providing valid results.

Accurate calibration helps to maintain public safety and integrity in DUI enforcement, as it ensures that the measurements taken will hold up in legal contexts. This regular maintenance schedule is critical in upholding standards of evidence in DUI cases. The timing of these checks aligns with best practices in maintaining scientific instruments that require ongoing verification to remain compliant with legal and operational standards.
