The "Chemical Testing " sub-section of this guide provides an examination of the protocols and legal standards governing the administration of chemical tests in DUI cases within Georgia.
Testing Requirements O.C.G.A § 40-6-392(a)(1)(A):
(A) Chemical analysis of the person's blood, urine, breath, or other bodily substance, to be considered valid under this Code section, shall have been performed according to methods approved by the Division of Forensic Sciences of the Georgia Bureau of Investigation on a machine which was operated with all its electronic and operating components prescribed by its manufacturer properly attached and in good working order and by an individual possessing a valid permit issued by the Division of Forensic Sciences for this purpose. The Division of Forensic Sciences of the Georgia Bureau of Investigation shall approve satisfactory techniques or methods to ascertain the qualifications and competence of individuals to conduct analyses and to issue permits, along with requirements for properly operating and maintaining any testing instruments, and to issue certificates certifying that instruments have met those requirements, which certificates and permits shall be subject to termination or revocation at the discretion of the Division of Forensic Sciences.
Breathalyzer Requirements O.C.G.A § 40-6-392(a)(1)(B):
(B) In all cases where the arrest is made on or after January 1, 1995, and the state selects breath testing, two sequential breath samples shall be requested for the testing of alcohol concentration. For either or both of these sequential samples to be admissible in the state's or plaintiff's case-in-chief, the readings shall not differ from each other by an alcohol concentration of greater than 0.020 grams and the lower of the two results shall be determinative for accusation and indictment purposes and administrative license suspension purposes. No more than two sequential series of a total of two adequate breath samples each shall be requested by the state; provided, however, that after an initial test in which the instrument indicates an adequate breath sample was given for analysis, any subsequent refusal to give additional breath samples shall not be construed as a refusal for purposes of suspension of a driver's license.
Independent Testing O.C.G.A § 40-6-392(a)(3):
(3) The person tested may have a physician or a qualified technician, chemist, registered nurse, or other qualified person of his own choosing administer a chemical test or tests in addition to any administered at the direction of a law enforcement officer. The justifiable failure or inability to obtain an additional test shall not preclude the admission of evidence relating to the test or tests taken at the direction of a law enforcement officer
Right to Results O.C.G.A § 40-6-392(a)(4):
(4) Upon the request of the person who shall submit to a chemical test or tests at the request of a law enforcement officer, full information concerning the test or tests shall be made available to him or his attorney.
Refusal of Test O.C.G.A § 40-6-392(d):
(d) In any criminal trial, the refusal of the defendant to permit a chemical analysis to be made of his blood, breath, urine, or other bodily substance at the time of his arrest shall be admissible in evidence against him.
