Comment on this story

The driver of a pickup truck was on Foothill Boulevard near the I-80/I-215 interchange when he drifted off the road for an unknown reason about 11 p.m. Tuesday, said Utah Highway Patrol Sgt. Danny Allen.

"It just looks like he might have fallen asleep," he said.

A passer-by spotted the wrecked and called 911. The driver, whose name and age were not immediately available, suffered critical injuries but he was wearing a seat belt.

"The seat belt did keep him from being ejected from from the truck," Allen said.

There was no evidence of impairment, he said.

Additional information will be posted as it becomes available.
