Janine Howard, 40, was driving a Chevrolet Cavalier with her four children inside south on U.S. Highway 89 about 3:30 p.m. when they were struck by a northbound Toyota Tacoma pickup that drifted into their lane near 2200 North.
The driver of the pickup, a 25-year-old man from the Ogden area, was conscious after the collision and was in stable condition Friday at Ogden Regional Hospital. He suffered a broken back and ankle, Holden said.
Police declined to release his name pending a criminal investigation.
Traffic was diverted from U.S. 89 for more than four hours while police investigated the collision. White sheets covered the passenger compartment of the car while the pickup remained on its roof with tires skyward.
Layton resident Kevin Ure was working on a computer in his nearby home when he heard the collision.
"It felt like a bomb," Ure said. "You could hear the crunch seconds after that. You could tell right away it was a bad one."
Collisions are not rare for the heavily traveled highway, he said.
"It can be a bad highway," he said.
