Heard about this crazy pileup on the news. Amazing that no one was seriously injured.

Quoted: Conditions on I-90 east of North Bend included gusty winds, blowing snow and compact snow and ice on the highway when the big rig jackknifed and collided with the trooper's car, Merrill said.

The trooper, who was unhurt, had been assisting a car that had rolled over about 15 minutes earlier at the same site, Merrill said. A truck towing a trailer came next, hitting the side of the tractor-trailer rig. Other vehicles soon followed, resulting in the 30-vehicle pileup, he said.
