Rock star Sawyer Hill revealed harrowing details about the terrifying rollover tour bus crash after the driver suffered a fatal medical emergency while behind the wheel.

Hill, 27, was traveling with his band and crew from Denver to Salt Lake City when suddenly they “hit a big bump” and cut across several lanes of a highway before flipping over into a ditch, he recounted in an Instagram video Friday.

The Arkansas-born singer recalled the bus “overcorrecting” from one side to the other, which is when he realized the situation was dire.

“Oh my God, this is about to happen. I’m about to die,” Hill said in the social media post.

“Everything starts shaking and metal starts scraping and then crash. I get thrown out of my bunk in complete darkness,” he said.

“The flashlights come on and our lighting guy is just bleeding profusely out of his face. Our merch person, whose trying to bandage him up is bleeding out of the back of her head,” Hill said of the chaos.

He then showed off his own gnarly leg bruise that spanned from his knee down to his ankle.

“[First responders] told us ‘You all should be dead. If you have a God you should be thanking Him.’ So, thank God and I wish we were all still here but we’re all lucky to be alive,” he said.

Hill thanked both first responders and fans who have donated over $20,000 on GoFundMe to support the tour bus driver David Jackson, 50, who was the sole casualty.
