A medical emergency involving the driver of a tanker truck carrying anhydrous ammonia was reported to be the cause of a fatal Oct. 10 accident on Interstate 10 near Willcox, Ariz., according to the Arizona Department of Public Safety (ADPS).
The ADPS said the emergency caused the tanker truck to drift out of the westbound lanes, cross a dirt median, and hit a box truck head on. The driver of the box truck sustained life-threatening injuries and his passenger, who was in a sleeper berth, was killed. The driver of the tanker truck sustained minor injuries.
A very small amount of anhydrous
ammonia was leaking after the collision. The remaining amount of the liquid was
transferred to another tanker.
The owner of the tractor-trailer carrying the ammonia was Kimrad Transport,
Amarillo, Texas, according to ADPS.
