The person shall also be entitled, upon request, to observe the process of analysis and to see the blood-alcohol reading on the equipment used to perform the breath test. His breath may be analyzed by any police officer of the Commonwealth, or of any county, city or town, or by any member of a sheriff’s department in the normal discharge of his duties.

D. Whenever the breath sample analysis indicates that alcohol is present in the person’s blood, the officer may charge the person with a violation of an offense listed in subsection A. The person so charged shall then be subject to the provisions of §§ 18.2-268.1 through 18.2-268.12, or of a similar ordinance.
