Local crash patterns can shape what evidence exists and which agencies or entities may have relevant records.
- I-90/94 (Kennedy/Dan Ryan), I-290 (Eisenhower), I-55 (Stevenson), and I-57: frequent stop-and-go traffic, sudden merges, and rear-end or sideswipe collisions involving tractor-trailers and box trucks.
- I-294 and key freight connectors near O’Hare and industrial corridors: heavy commercial volume, tight delivery windows, and more complex company chains (carrier, broker, shipper).
- Downtown and near-the-Loop delivery zones: box trucks and straight trucks navigating narrow lanes, buses, cyclists, pedestrians, and rideshare pick-ups.
- Construction season bottlenecks: lane shifts and reduced shoulders can intensify the severity of a crash and complicate scene documentation.
Why it matters: urban corridors often have camera coverage, business surveillance, CTA/bus-adjacent footage, and IDOT-related records that may need to be requested quickly—sometimes before video is overwritten.
