The National Transportation Safety Board (NTSB) has released the docket for its investigation into a deadly crash near Teutopolis, Illinois, which occurred in September 2023. The incident, involving a semi-truck carrying anhydrous ammonia, resulted in the deaths of five people, multiple hospitalizations, and the evacuation of a significant portion of the community due to toxic fumes.

The crash happened when the truck swerved to avoid another vehicle in a construction zone on Highway 40, causing it to overturn and release the hazardous substance. The NTSB’s docket includes a preliminary report, a reconstruction from the Illinois State Police, and detailed information on the hazardous materials and other factors related to the accident.

State Representative Brad Halbrook (R-Shelbyville) expressed relief that the investigation is progressing and that the NTSB will continue its analysis to issue safety recommendations. Halbrook has been advocating for stronger communication between the Illinois Department of Transportation and local authorities. He introduced legislation earlier this year to improve information sharing on construction projects, which stalled in the House but has garnered support from local law enforcement. Halbrook plans to reintroduce the bill.
