This is one of those accidents that may have been able to be avoided but unfortunately the roads were slick and the driver did not move over for a tow truck on the side of the road.

This tow truck was in the middle of cleaning up another crash on I-84 that had happened earlier when shocking dash cam footage shows a truck traveling semi fastly slam into the tow truck and the vehicle it was getting ready to tow. The truck barely missed hitting people that were around the area.

Idahonews.com shared the story and when I watched it I was in shock. They stated that : The driver of the pickup had to be extricated from her vehicle. 

In the full article they talk about tow trucks or emergency vehicles on the side of the road, really anyone on the side of the road you should move over for and if conditions are bad especially. Also give yourself enough time to do get over too.
