Naperville traffic patterns aren’t the same as rural Illinois. Many DUI-related crashes occur around the times people are commuting—morning departures, after-work travel, and late-evening returns from dining and events. That matters because crash evidence often depends on:
- Which roads were involved and how traffic flowed at that time
- Visibility and lighting conditions near intersections and turning lanes
- Whether there were nearby cameras (businesses, apartment complexes, or traffic monitoring systems)
- Witness proximity—who saw the vehicle before impact versus only the collision
A small delay in gathering the right information can make a difference in what can still be obtained, preserved, and used.
