 c. Convictions or the equivalent of deferred judgments for violations in any other states under statutes substantially corresponding to this section shall be counted as previous offenses. The courts shall judicially notice the statutes of other states which define offenses substantially equivalent to the one defined in this section and can therefore be considered corresponding statutes. Each previous violation on which conviction or deferral of judgment was entered prior to the date of the violation charged shall be considered and counted as a separate previous offense.
 9. A person shall not be convicted and sentenced for more than one violation of this section for actions arising out of the same event or occurrence, even if the event or occurrence involves more than one of the conditions specified in subsection 1.

 b. When charged with a violation of subsection 1, paragraph “c”, a person may assert, as an affirmative defense, that the controlled substance present in the person’s blood or urine was prescribed or dispensed for the person and was taken in accordance with the directions of a practitioner and the labeling directions of the pharmacy, as that person and place of business are defined in section 155A.3.
 12. In any prosecution under this section, evidence of the results of analysis of a specimen of the defendant’s blood, breath, or urine is admissible upon proof of a proper foundation.

 a. The alcohol concentration established by the results of an analysis of a specimen of the defendant’s blood, breath, or urine withdrawn within two hours after the defendant was driving or in physical control of a motor vehicle is presumed to be the alcohol concentration at the time of driving or being in physical control of the motor vehicle.
 b. The presence of a controlled substance or other drug established by the results of analysis of a specimen of the defendant’s blood or urine withdrawn within two hours after the defendant was driving or in physical control of a motor vehicle is presumed to show the presence of such controlled substance or other drug in the defendant at the time of driving or being in physical control of the motor vehicle.
 c. The department of public safety shall adopt nationally accepted standards for determining detectable levels of controlled substances in the division of criminal investigation’s initial laboratory screening test for controlled substances.
 13. a. In addition to any fine or penalty imposed under this chapter, the court shall order a defendant convicted of or receiving a deferred judgment for a violation of this section to make restitution for damages resulting directly from the violation, to the victim, pursuant to chapter 910. An amount paid pursuant to this restitution order shall be credited toward any adverse judgment in a subsequent civil proceeding arising from the same occurrence. However, other than establishing a credit, a restitution proceeding pursuant to this section shall not be given evidentiary or preclusive effect in a subsequent civil proceeding arising from the same occurrence.

 b. The court may order restitution paid to any public agency for the costs of the emergency response resulting from the actions constituting a violation of this section, not exceeding five hundred dollars per public agency for each such response. For the purposes of this paragraph, “emergency response” means any incident requiring response by fire fighting, law enforcement, ambulance, medical, or other emergency services. A public agency seeking such restitution shall consult with the county attorney regarding the expenses incurred by the public agency, and the county attorney may include the expenses in the statement of pecuniary damages pursuant to section 910.3.
 14. In any prosecution under this section, the results of a chemical test shall not be used to prove a violation of subsection 1, paragraph “b” or “c”, if the alcohol, controlled substance, or other drug concentration indicated by the chemical test minus the established margin of error inherent in the device or method used to conduct the chemical test does not equal or exceed the level prohibited by subsection 1, paragraph “b” or “c”.
