Death by decapitation due to trailer underride can result when tractor trailers park on the roadside.
The kneejerk response of most people seeing pictures of these incidents is to simply blame the dead person. But it’s not that simple. When an innocent passenger is killed or maimed, some portion of fault is normally apportioned to the driver who departed from the traffic lane for whatever reason. But it is necessary to also examine a trucking company’s decision to violate safety standards by parking a big rig on the side of the road.
