SALT LAKE CITY — Part-time Uber driver Spencer Johnson had just picked up a passenger in downtown Salt Lake City on Jan. 19 when he saw a car in front of him swerve to the left and hit something in the road in front of them.

“I saw something get hit,” Johnson said. “At first I thought it was debris, like a garbage bag in the road.”

But what that white Chevrolet Impala hit was actually a man crossing the street at 900 S. West Temple at about 1:30 a.m.

Johnson’s car has a dashboard camera, which captured the car hitting the man and then veering to the right, entering the freeway and accelerating away from the intersection where the accident happened Wednesday night. As Johnson’s car approaches, the man who was hit can be seen, clearly dazed, standing up amid debris strewn on the road around him.

“I noticed there was a person there,” Johnson said. “He got up. He was kind of in shock. ... He was looking to see no other cars were coming.”

The man went to the side of the road to lie down.

Police said the pedestrian, whose name wasn’t released, was crossing against a red light, and Johnson said the Impala signaled that the driver intended to change lanes just before the accident.

“We’d really like to get their side of what happened,” said Salt Lake Police Sgt. Keith Horrocks. “There is a very small off chance, that maybe they don’t know they hit a person.”

Johnson is skeptical of that. He points to the debris on the road as evidence that the impact was significant, even if the man’s injuries were not.

“I think he (the driver) knew he hit somebody, and he didn’t want to stop,” Johnson said. “It’s just common courtesy to help.”

Police are asking for help in locating the driver of the white Chevrolet Impala, likely a model from 2011 to 2013.
