A woman was seriously injured Tuesday evening after her pickup truck collided with a semi-tractor trailer, she lost consciousness, her foot slipped onto the accelerator, and she drove more than 700 feet before the truck vaulted over a culvert and flipped onto its side, said Cpl. Jennifer Miller, spokeswoman for the Prescott Valley Police Department.
At 6:42 p.m., Prescott Valley police answered a call about a traffic collision at the intersection of Highway 89A and Viewpoint Drive.
Witnesses told officers that a red 1999 Chevrolet pickup truck driven by Rae Gustafson, 34, of Prescott Valley appeared to enter the intersection against a red traffic light, Miller said.
A semi-tractor trailer driven by Chad Hymas, 43, of Glendale, traveling westbound on Highway 89A, then struck Gustafson's pickup truck, Miller said.
"After the impact of the collision, she became unconscious and her foot ended up on the gas pedal," Miller said. "She and her three children who were in the vehicle with her traveled 770 feet on the westbound 89A on-ramp before leaving the roadway and hitting a barbed-wire and chain-link fence."
The pickup truck then traveled three-tenths of a mile before vaulting over a culvert and flipping onto the passenger side of the vehicle.
Gustafson sustained head trauma and was airlifted to St. Joseph's Hospital in Phoenix, Miller said.
"The children were properly restrained in the vehicle and only sustained minor injuries," Miller said. The children were ages 13, 11 and 6.
There was no report that Hymas had sustained any injuries as a result of the collision.
The collision remains under investigation, but impairment does not appear to be a factor, Miller said.
