Josh McCutchen, a YouTube star known as Burger Planet who streams his road trips live, was filming when he captured a tractor-trailer barreling past him.
“I was just so bewildered about what just happened, like, 'Where the hell did that come from?' The thing just came out of nowhere!” he told Inside Edition.
Moments later, the highway was in flames. He went into reporter mode as thousands of his followers watched the drama unfold.
“Tires started exploding and cars and stuff. It sounded like a war zone, things were exploding. I was worried that there was a big tanker truck and the tanker was going to explode or something.”
In the midst of the blaze, dozens of two-by-fours were spread across the highway, feeding the flames.
“If I was a little bit farther up in the line that could have been me in there somewhere,” McCutchen said.
At least four people are dead and the death toll may rise.
The 23-year-old driver of another vehicle has been charged with vehicular homicide. Authorities believe he was going too fast in a flatbed truck and plowed into cars that had stopped due to an earlier accident.
