A deadly collision between two vehicles ... each driven by elderly drivers ... is being blamed on one driver not yielding.
Oklahoma Highway Patrol troopers say a 2005 Chevy Venture Van driven by 80-year-old Sue Sahmaunt of Lawton was heading eastbound on Wolf Road around 10 :15 this morning.
At the same time ... a 2003 Ford F350 pickup driven by 72-year-old Clarence Hardzog, Jr., from Elgin, was heading north on State Highway 58.
Troopers say the woman driving the van didn't yield at the stop sign and hit the truck on its left rear tire.
The truck left the roadway and rolled several times.
Mr. Hardzog was ejected and died at the scene from massive injuries.
The other driver was treated and released from the hospital
