Investigation of motor vehicle crashes involving peace officers

1. In a county whose population is 100,000 or more, each law enforcement agency shall adopt policies and procedures to govern the investigation of motor vehicle crashes in which a peace officer employed by the law enforcement agency is involved. The policies and procedures must include, without limitation, a requirement that if such a motor vehicle crash results in a fatal injury to any person, the motor vehicle crash must be investigated by a law enforcement agency other than the law enforcement agency that employs the peace officer involved in the crash unless: (a) Another law enforcement agency does not have comparable equipment and personnel to investigate the crash at least as effectively as the law enforcement agency that employs the peace officer involved in the motor vehicle crash; (b) Another law enforcement agency is unavailable to investigate the motor vehicle crash; or (c) Investigation of the motor vehicle crash by another law enforcement agency would delay the initiation of the investigation such that the integrity of the crash scene and preservation and collection of evidence may be jeopardized by such a delay. 2. This section does not prohibit a law enforcement agency in a county whose population is 100,000 or more from entering into agreements for cooperation with agencies in other jurisdictions for the investigation of motor vehicle crashes in which a peace officer of the law enforcement agency is involved.
