When recording a breath test, use the driver’s license number as the primary identifier. If a control number is available, include it as well because it links the test to a specific person and to the instrument’s QA data, enhancing traceability and accuracy. Leaving the field empty or using unknown/none/skip creates an audit trail gap and can raise questions about the test’s validity. Therefore, the best practice is to enter the ID number and the control number if available.
