The accident happened as Josh, 38, was driving home from Thanksgiving dinner with his wife and children near Holladay, Utah.
He said he exited I-215 South and came to stop at an intersection when a "vehicle traveling at highway speed passed narrowly by my car, through the intersection and into the kitchen of a home across the street.
“I drove to the accident site and entered the home where the car had come to a stop on its side. I opened the driver side door and spoke with the four passengers inside the car. Miraculously, they appeared to have no major injuries. I was able to help each of them get out of the car and lift them down to the ground," he said.
Josh caught flack Friday for posting a photograph of himself grinning alongside the damaged vehicle and home on Twitter with the caption, "Was first on scene to big accident, see pic of car in the house. I lifted 4 people out to safety. All ok. Thankful."

The so-called "humble brag" left a bad taste in some peoples' mouths, the New York Daily News reported.
"Why are you smiling like a tourist at such a horrific scene?" one person asked on social media, the newspaper reported.
"You took and posted a smiley tourist-type photo of it? Bit odd," another said on Twitter.
