What role does a certified BTO play after a DUI arrest?

A certified Breath Test Operator (BTO) plays a crucial role after a DUI arrest by engaging in face-to-face monitoring of the driver. This responsibility is essential to ensure the integrity of the breath testing process. The BTO observes the driver to prevent any tampering with the breath test equipment or samples, ensuring that the procedure follows protocols in an unbiased and correct manner. This monitoring is a legal requirement to maintain the validity of the evidence collected during the DUI arrest.

Proper face-to-face monitoring contributes to the reliability of the breath test results, as it helps confirm that the driver has not consumed any additional alcohol or substances that could affect the outcome before the test is administered. By maintaining this oversight, the BTO helps uphold the standards of the testing process, which is critical in legal proceedings related to DUI charges.
