Which reason is NOT one of the purposes for investigating traffic crashes?

Investigating traffic crashes serves several critical purposes that impact both law enforcement and the broader community. The primary goals include determining the cause of the crash for legal action, ensuring public safety by identifying dangerous conditions or behaviors, and gathering information that may be relevant for civil liability claims.

Improving community relations, while an important aspect of policing in general, is not a primary purpose of traffic crash investigations. The focus of these investigations is more on the immediate factors surrounding the crash and the enforcement of traffic laws to ensure safety on the roads, rather than on fostering relationships within the community. This distinction highlights the primary role of crash investigations in enhancing the safety and legality of roadway use rather than serving as a tool for community engagement.
