VIDEO - Winter Driving Awareness
This is a video from the Montana Highway Patrol. While it's focus is on winter driving, you could remove the word "winter" from the title and still have a video that is on topic. The video was taken from the camera in a patrol car at the scene of a minor collision on an interstate highway. Watch as it quickly goes from a minor incident to a series of major collisions. It was always the stuff of nightmares for me when I worked on high speed highways because I knew that the drivers around me were not slowing down and could be well past the point of no return before they realized it.
While the video might have benefitted from a demonstration of what drivers faced approaching the scene and how to have properly reacted to the situation it does show quite clearly what happens when they do not. Don't follow their example.
