In Teutopolis, Illinois, the major incident people usually mean is the deadly September 2023 tanker crash on U.S. 40 that released anhydrous ammonia and forced a town evacuation. Five people were killed, several others were injured, and about 500 residents were evacuated.

What happened

A tanker truck carrying anhydrous ammonia overturned after a crash on U.S. 40 near Teutopolis, and the chemical leaked into the area. Officials said the ammonia plume created dangerous air conditions and delayed some emergency response until the scene was safer.

Impact

  • Five people died, including three members of one family and two out-of-state motorists.
  • About 500 residents were evacuated from the immediate area.
  • The crash injured additional people, and later reporting described nine serious injuries.
  • The NTSB later released a final report on the crash and identified the sequence of events leading to the release.

Why it’s still talked about

The incident was widely covered because it combined a fatal highway crash, a hazardous chemical spill, and a large emergency evacuation in a small community. Teutopolis later added backup alerting measures after some residents did not receive the first evacuation notice.
