Earlier this week I was writing an article on Defensive Driving. One of the big things that it is difficult to defend against is being hit from behind. Managing both the speed of your vehicle and the space around it will help avoid most rear end shunts. However when it comes to being hit from behind with a truck it seems there is really no defence at all. During a bit of research I found a couple of videos that illustrate this. This first video is a set up and illustrates the forces that occur when 44 tons hit a stationary car.

From comments it seems the driver of the offending truck was texting on a mobile at the time. Please do not watch if you are easily shocked.
