An 18-year-old Provo man was killed Monday when the truck he was driving rolled over— reportedly after it collided with another vehicle while the two were racing.

Eric E. Blackham was ejected from his 1975 Ford pickup truck and died at the scene, according to the Utah Highway Patrol.

According to a UHP news release, witnesses said Blackham’s truck and a 2004 Chevrolet Silverado were both traveling north on State Road 147 about 5:15 p.m. when “the driver of the Chevy pulled up alongside the driver of the Ford.” The witnesses told UHP “there appeared to be a mutual racing-type occurrence between the two vehicles,” and that as the two vehicles accelerated “a side-swipe crash occurred.”

Blackham’s pickup truck “drove off the left side of roadway, overcorrected, went off the road to the right, and rolled over” at 8033 S. 5600 West, troopers wrote.

A juvenile passenger in the truck was taken to a hospital with minor injuries; the driver of the Chevy and his passenger were uninjured.

According to the UHP, all four people in the vehicles were 18 or younger. The investigation into the crash is continuing.
