By "speeding", the DETR means speed that is merely higher than the posted limit. It claims that speed is a factor in about a third of all collisions. The way it has arrived at this figure is bizarre, however.
If any of the vehicles involved in a road accident was travelling in excess of the posted speed limit immediately prior to the crash, the DETR chalks it up as speed-related.
So if someone runs a red light and clobbers another vehicle which is doing 35mph in a 30mph area it is considered a speed-related accident.
This clearly has no meaning in reality. The DETR might as well observe the footwear of drivers involved in collisions, and declare that white socks are a factor in an as yet indeterminate proportion of road accidents.
