A chain-reaction crash resulted in a multi-vehicle pileup along a major west Michigan highway. The year 2017 ended with winter weather wreaking havoc on roads. Dozens of vehicles ended up in ditches Sunday afternoon after a massive pileup along westbound I-94 between the Lawrence and Mattawan exits. Drivers said slippery roads and whiteout conditions led to the pileup. "You couldn’t see, you just could not see. You’re afraid to stop because someone could hit you. You’re afraid to keep going because you don’t know what is up there," driver Alan Rose said.
