Michigan resident Eric Teschke said he had just told his friend who was driving that they should probably slow down when trouble began.
"I look up and I just see a sea of cars and I go, 'Oh, crap, oh, crap.' And I just go 'We can't stop,' " Teschke said. "So we're sliding for about 15 seconds, knowing what's going to happen. Bam, slam into the back of several cars and a semi."
Michigan State Police's Matthew Churchill said it was the worst pile-up he's ever seen.
"Vehicles were actually crashing right in front of us, and there was really nothing we could do except to try to stay out of the way and try to get to the people and keep them in their vehicles where they could be safe," Churchill said.
