Chicago traffic and street design create real-world patterns we see often after DUI crashes:
- Cross-street collisions and turning crashes near busy intersections where timing and signal phases matter.
- Pedestrian and bike involvement in high-foot-traffic areas, including after-event crowds and weekend nightlife.
- Lane changes on expressways/arterials (and disputes about speed, braking distance, and visibility).
- Construction zones and detours that can affect driver sightlines and how officers document the scene.
When a case involves these factors, the evidence isn’t just “who was impaired.” It’s also what the roadway conditions were, what witnesses observed, and what documentation still exists—before it’s overwritten or lost.
