No person is required to submit to more than one test for any one offense for which he has been charged, and the test must be administered as soon as practicable without undue delay.
The person tested may have a physician, qualified technician, chemist, registered nurse, or other qualified person of his own choosing conduct a test or tests in addition to the test administered by the law enforcement officer. The failure or inability of the person tested to obtain an additional test does not preclude the admission of evidence relating to the test taken at the direction of the law enforcement agency or officer.
The arresting officer and the person conducting the test shall inform the person tested of his right to obtain an additional test, and the arresting officer or the person conducting the chemical test of the person apprehended promptly shall assist that person to contact a qualified person to conduct additional tests.
The division shall administer the provisions of this subsection and may make regulations as may be necessary to carry out its provisions. The Department of Health and Environmental Control and SLED shall cooperate with the division in carrying out its duties.
The provisions of this subsection do not limit the introduction of any other competent evidence bearing upon the question whether or not the defendant was under the influence of alcohol. Nothing contained in this section prohibits the introduction of:
At trial, a person charged with a violation of this section is entitled to a jury instruction stating that the factors enumerated above and the totality of the evidence produced at trial may be used by the jury to determine guilt or innocence. A person charged with a violation of this section must be given notice of intent to prosecute under the provisions of this section at least fourteen days before his trial date.
Notwithstanding another provision of law, a person charged with a violation of this section has the right to compulsory process for obtaining witnesses, documents, or both, including, but not limited to, state employees charged with the maintenance of breath testing devices in this State and the administration of breath testing pursuant to this chapter. This process may be issued under the official signature of the magistrate, judge, clerk, or other officer of the court of competent jurisdiction. The term "documents" includes, but is not limited to, a copy of the computer software program of breath testing devices. The portion of compulsory process provided for in this section that requires the attendance, at any administrative hearing or court proceeding, of state employees charged with the maintenance of breath testing devices in this State and the administration of breath testing pursuant to this article, takes effect once the compulsory process program at SLED is specifically, fully, and adequately funded.
In addition, at the time of arrest for a violation of this section, the arresting officer, in addition to other notice requirements, must inform the defendant of his right to all hearings provided by law to include those if a breath test is refused or taken with a result that would require license suspension. The arresting officer, if the defendant wishes to avail himself of any hearings, depending on the choices made or the breath test results obtained, must provide the defendant with the appropriate form to request the hearing. The defendant must acknowledge receipt of the notice requirements and receipt of the hearing form if a hearing is desired.
