Which section of the CR-100 addresses the investigator's narrative requirements?

The correct choice emphasizes the comprehensive nature of the investigator's narrative requirements as outlined in the CR-100. In this context, the Field Diagram provides a visual representation of the scene, detailing the layout and positioning of vehicles, which is crucial for understanding the incident as a whole. The Contributing Factors section identifies and elaborates on elements that may have led to the incident, such as driver behavior or environmental conditions, which helps in assessing the causes and circumstances surrounding the event.

By addressing both the Field Diagram and Contributing Factors, the investigator can offer a well-rounded narrative. This combination not only conveys the factual details of the incident through visual aids but also explains the rationale behind those details, creating a comprehensive account that can aid law enforcement, legal processes, and future prevention strategies. This integrated approach ensures that all relevant aspects of the investigation are covered effectively, which is essential for thorough documentation and analysis.
