Which is an outcome used to improve traffic safety from crash investigations?

Developing trends in vehicle or highway design represents a proactive approach to improving traffic safety that is directly informed by the findings from crash investigations. When law enforcement and safety analysts review the circumstances surrounding vehicle crashes, they can identify recurring issues that may relate to the design of the roadways or the vehicles themselves.

For example, crash data might reveal that certain intersections have a higher incidence of accidents due to poor visibility or a lack of turning lanes. This data can lead to recommendations for redesigning those intersections, implementing traffic calming measures, or utilizing innovative safety features in vehicle design. By addressing these trends through thoughtful engineering and design changes, potential hazards can be mitigated before they lead to further accidents, ultimately enhancing overall safety on the roads.

In contrast, other options like increasing penalties or providing legal advice focus on reactive measures rather than systemic changes that enhance safety through informed design improvements.
