The National Transportation Safety Board has released its final report on the crash east of Teutopolis that led to a release of anhydrous ammonia. The incident resulted in five fatalities, serious injuries to nine people, and minor injuries to four others.

The NTSB determined that the probable cause of the roadway departure and overturning of a combination vehicle “was the unsafe passing maneuver by a teen driver that caused the combination vehicle driver to initiate an evasive action that resulted in loss of vehicle control and rollover.” The findings indicate that contributing to the severity of the crash was the subsequent impact of the overturned cargo tank with a parked utility trailer that resulted in the release of the anhydrous.
