BETHEL TOWNSHIP -- "It just turned real white."

Raul Jardine of Allentown was driving along Interstate 78 in Lebanon County Saturday morning, heading west, when a sudden whiteout swept across the highway.

Jardine told PennLive, in that moment, all he could see were the brake lights of the car in front of him. He slowed down and was hit from behind.

Chaos erupted.

At least 30 cars and tractor trailers were involved and left smashed up along the Interstate. Crumbled, overturned and crushed vehicles. Shattered windshields.

Tiny cars pinned between tractor trailers.

At least three people have been killed, and numerous travelers were injured. Seven so far have been transported to the Penn State Milton S. Hershey Medical Center, two with critical injuries.

At the scene of the crash, as emergency crews worked to free trapped drivers, large crowds waited in what appeared to be a make-shift shelter inside at tractor-trailer. Covered with blankets, clutching their belongings, snow crusted to their pants, they shivered in the cold, blowing wind, waiting to be transported to nearby shelters.

Crashed vehicles still line the road and the median, but as of 1 p.m., it appeared everyone had been removed from the scene.
