Windsor, Ill.-One of two drivers and a passenger were killed in a head-on collision Nov. 1 between a semi-truck pulling an anhydrous ammonia tank and an armored vehicle. The accident closed down Illinois 16/32 about one mile south of here in Shelby County into the evening while cleanup, including transfer of the ammonia, took place. Few details about the collisions were available from Illinois State Police investigators or Shelby County sheriff’s deputies, who also responded. But those on the scene reported that although the collision with the Garda armored vehicle at approximately 5 p.m. spread currency over the highway, little, if any, ammonia was allowed to escape. State police said the accident resulted from one of the drivers trying to pass another car stopped in front of him and cutting into the path of the other truck. Both trucks overturned and came to rest in a ditch on the east side of Illinois 16. A passenger was thrown from one of the trucks, and died, while the driver of the other died inside his truck after it caught fire. The driver of the other truck, who was taken to a nearby hospital, was ticketed for improper passing.
