The act repeals the requirement for coroners, or other officials performing like functions, to report to the department of transportation (department) deaths resulting from traffic accidents on a monthly basis. The act requires coroners, or other officials performing like functions, to report all available toxicology results to the department for each deceased party who has died as a result of a motor vehicle crash. The report must be submitted by the final business day of each quarter of the calendar year.     If a participant in a crash dies within 30 days as a result of a crash, the act requires the law enforcement officer who was notified of, or investigated, the crash to submit an amended report to the department within five days after receiving a notification of the death.(Note: This summary applies to this bill as enacted.)
