(2) With the exception of the results of the tests administered pursuant to KRS 189A.103(7): (a) If the sample of the person's blood or breath that is used to determine the alcohol concentration thereof was obtained more than two (2) hours after cessation of operation or physical control of a motor vehicle, the results of the test or tests shall be inadmissible as evidence in a prosecution under subsection (1)(a) or (f) of this section. The results of the test or tests, however, may be admissible in a prosecution under subsection (1)(b) or (e) of this section; or (b) If the sample of the person's blood that is used to determine the presence of a controlled substance was obtained more than two (2) hours after cessation of operation or physical control of a motor vehicle, the results of the test or tests shall be inadmissible as evidence in a prosecution under subsection (1)(d) of this section. The results of the test or tests, however, may be admissible in a prosecution under subsection (1)(c) or (e) of this section. (3) In any prosecution for a violation of subsection (1)(b) or (e) of this section in which the defendant is charged with having operated or been in physical control of a motor vehicle while under the influence of alcohol, the alcohol concentration in the  defendant's blood as determined at the time of making analysis of his blood or breath shall give rise to the following presumptions: (a) If there was an alcohol concentration of less than 0.04 based upon the definition of alcohol concentration in KRS 189A.005, it shall be presumed that the defendant was not under the influence of alcohol; and (b) If there was an alcohol concentration of 0.04 or greater but less than 0.08 based upon the definition of alcohol concentration in KRS 189A.005, that fact shall not constitute a presumption that the defendant either was or was not under the influence of alcohol, but that fact may be considered, together with other competent evidence, in determining the guilt or innocence of the defendant. The provisions of this subsection shall not be construed as limiting the introduction of any other competent evidence bearing upon the questions of whether the defendant was under the influence of alcohol or other substances, in any prosecution for a violation of subsection (1)(b) or (e) of this section. (4) (a) Except as provided in paragraph (b) of this subsection, the fact that any person charged with violation of subsection (1) of this section is legally entitled to use any substance, including alcohol, shall not constitute a defense against any charge of violation of subsection (1) of this section.
