Of the hundreds of crashes, four patrol cars were hit, putting trooper's lives in danger and of course backing up traffic.
Several veteran troopers tell ABC 4 they can't remember this many trooper involved crashes in one day.
The crashes were along Interstate 15 in the Wasatch Front. The most dramatic crash took place on southbound I-15 at about 1000 South. The trooper was in his car for the first collision, but stepped out of his car moments before the second impact.
"I remember backing out of my car and taking one step back. I turned around so I'd be protected. I remember seeing glass and car parts fly past my head and then the force of the car taking me with it. The only thing I could think of was just how I had said goodbye for the day to my wife and my little daughter just 20 minutes before that happened," said Trooper Kristopher Cope.
Kristopher reunited with his wife Megan and his twelve-week-old daughter Navy. He is recovering with stitches to his hand and a badly bruised right leg where his car slammed into his body.
He was protected by a crashed car parked between his vehicle and the car speeding toward him.
