When a vehicle rolls over and results in injuries to all occupants, it’s essential that the investigation addresses all potential contributing factors to determine how and why the loss of control occurred. In the April 4th incident involving a Ford Explorer near Big Timber Road and Illinois Route 72, where five individuals were injured in a rollover, investigators should begin with three fundamental questions: (1) Did the authorities thoroughly investigate the crash? (2) Has anyone looked into the possibility that a vehicle defect caused or contributed to the crash? (3) Has all the electronic data relating to the crash been collected?

Rollover accidents often indicate a sudden change in direction, overcorrection, or instability, all of which can be influenced by road design, vehicle handling characteristics, or driver response. Investigators should assess the road surface, signage, lighting, and whether there were any environmental factors—such as sharp curves or obstacles—that might have triggered the loss of control. The trajectory of the vehicle and rollover pattern can help determine whether speed, road conditions, or steering input played a role.

The Ford Explorer, like many SUVs, has a higher center of gravity, making it more susceptible to rollovers, especially during abrupt maneuvers or on uneven terrain. A mechanical inspection is critical to evaluate whether a component failure—such as a steering system malfunction, suspension problem, or tire blowout—contributed to the crash. Investigators should also review whether the vehicle’s stability control and rollover mitigation systems were functioning as designed.

Finally, the vehicle’s electronic control module (ECM) may hold crucial data about the moments before the rollover. This includes speed, brake application, throttle input, and steering angle. This information can help clarify whether the driver attempted to correct a skid, accelerate, or brake just prior to the incident, and whether the vehicle responded appropriately. Prompt retrieval of this data is necessary, especially in a crash involving significant damage and multiple injuries.

Until these three investigative areas are fully addressed, the cause of the rollover remains incomplete. A comprehensive review—encompassing crash scene analysis, vehicle inspection, and digital data retrieval—is essential not only to determine the cause of this incident but also to identify whether any factors can be mitigated to improve vehicle safety and road design in the future.
