In any prosecution under this subdivision, it is a rebuttable presumption that the person had 0.08 percent or more, by weight, of alcohol in his or her blood at the time of driving the vehicle if the person had 0.08 percent or more, by weight, of alcohol in his or her blood at the time of the performance of a chemical test within three hours after driving.

(c) In proving the person neglected any duty imposed by law in driving the vehicle, it is not necessary to prove that any specific section of this code was violated.

hours after driving.

(e) This section shall become operative on January 1, 1992, and shall remain operative until the director determines that federal regulations adopted pursuant to the Commercial Motor Vehicle Act of 1986 (49 U.S.C. Sec. 2701 et seq.) contained in Section 383.51 or 391.15 of Title 49 of the Code of Federal Regulations do not require the state to prohibit operation of commercial vehicles when the operator has a concentration of alcohol in his or her blood of 0.04 percent by weight or more.
