Sec. 15. (a) At any proceeding concerning an offense under IC 9-30-5 or a violation under IC 9-30-15, evidence of the alcohol concentration that was in the blood of the person charged with the offense:
(1) at the time of the alleged violation; or
(2) within the time allowed for testing under section 2 of this chapter;
as shown by an analysis of the person's breath, blood, urine, or other bodily substance is admissible.
(b) If, in a prosecution for an offense under IC 9-30-5, evidence establishes that:
(1) a chemical test was performed on a test sample taken from the person charged with the offense within the period of time allowed for testing under section 2 of this chapter; and
(2) the person charged with the offense had an alcohol concentration equivalent to at least eight-hundredths (0.08) gram of alcohol per:
(A) one hundred (100) milliliters of the person's blood at the time the test sample was taken; or
(B) two hundred ten (210) liters of the person's breath;
the trier of fact shall presume that the person charged with the offense had an alcohol concentration equivalent to at least eight-hundredths (0.08) gram of alcohol per one hundred (100) milliliters of the person's blood or per two hundred ten (210) liters of the person's breath at the time the person operated the vehicle. However, this presumption is rebuttable.
(c) If evidence in an action for a violation under IC 9-30-5-8.5 establishes that:
(1) a chemical test was performed on a test sample taken from the person charged with the violation within the time allowed for testing under section 2 of this chapter; and

(A) was less than twenty-one (21) years of age at the time of the alleged violation; and
(B) had an alcohol concentration equivalent to at least two-hundredths (0.02) gram of alcohol per:
(i) one hundred (100) milliliters of the person's blood; or
(ii) two hundred ten (210) liters of the person's breath;
at the time the test sample was taken;
the trier of fact shall presume that the person charged with the violation had an alcohol concentration equivalent to at least two-hundredths (0.02) gram of alcohol per one hundred (100) milliliters of the person's blood or per two hundred ten (210) liters of the person's breath at the time the person operated the vehicle. However, the presumption is rebuttable.
(d) If, in an action for a violation under IC 9-30-15, evidence establishes that:
(1) a chemical test was performed on a test sample taken from the person charged with the offense within the time allowed for testing under section 2 of this chapter; and
(2) the person charged with the offense had an alcohol concentration equivalent to at least four-hundredths (0.04) gram of alcohol per:
(A) one hundred (100) milliliters of the person's blood; or
(B) two hundred ten (210) liters of the person's breath;
at the time the test sample was taken;
the trier of fact shall presume that the person charged with the offense had an alcohol concentration equivalent to at least four-hundredths (0.04) gram of alcohol by weight in grams per one hundred (100) milliliters of the person's blood or per two hundred ten (210) liters of the person's breath at the time the person operated the vehicle. However, this presumption is rebuttable.
