How many test records must the chemical analyst sign?

• A. One
• B. Two
• C. None
• D. All copies

Answer: (D)

The key idea is that the chemical analyst must certify and authenticate every test record that accompanies the breath test results. All copies must be signed by the analyst. This creates a verifiable, auditable trail showing that the results were reviewed, the instrument was functioning properly, and no changes were made after signing. Each copy goes to a different recipient (such as the agency, the officer, the subject, and the lab file), so signing every copy ensures consistency and accountability across the entire record. If any copy were unsigned, it could open a gap for misrepresentation or tampering. Signing all copies prevents that and maintains the integrity of the entire documentation.
