§ 321J.15 Evidence in any action
321J.15. Evidence in any action
Upon the trial of a civil or criminal action or proceeding arising out of acts alleged to have been committed by a person while operating a motor vehicle in violation of section 321J.2 or 321J.2A, evidence of the alcohol concentration or the presence of a controlled substance or other drugs in the person's body at the time of the act alleged as shown by a chemical analysis of the person's blood, breath, or urine is admissible. If it is established at trial that an analysis of a breath specimen was performed by a certified operator using a device intended to determine alcohol concentration and methods approved by the commissioner of public safety, no further foundation is necessary for introduction of the evidence.
