Excessive Speed for the Conditions and Exceeding the Speed limit are two separate issues.
Exactly. They should never be added, and in fact a great deal of effort was put into ensuring that they were recorded separately in the new contibutory factors system.
See this PR Safe Speed issued 28th September 2006:
PR369: Don't add chalk and cheese.
news: for immediate release
In the new contributory factors figures published today, DfT chooses to add
'speeding' to 'inappropriate speed' to create an aggregate 'excessive speed'
figure.
There is absolutely no practical road safety basis for this addition. The
underlying behaviours are completely different - it is like adding chalk and
cheese.
Most news organisations are quoting that 15% of crashes and 26% of fatal
crashes have excessive speed as a contributory factor. They are being cheated
by DfT spin.
Reality differs. It is not reasonable to add 'legal compliance failure' (i.e.
speeding) to inappropriate speed which is a driver quality / driver judgement
issue.
'Speeding' is about legal compliance. It can be enforced by speed camera.
Inappropriate speed is about driver judgement. Speed cameras CANNOT affect it.
It takes place entirely WITHIN the speed limit. It is affected by driver skill
(or lack of it).
Paul Smith, founder of the Safe Speed road safety campaign
(
www.safespeed.org.uk) said: "There was a very good reason when the forms were
designed to separate speeding (in excess of a speed limit) from inappropriate
speed for the conditions. Adding these figures after the researchers were so
careful to separate them only serves those who wish to mislead and defend
failing policy."
"I am disgusted that DfT lumps these figures together in a further distortion
of road safety truth."
"The truth is that 5% of crashes (and 12% of fatal crashes) involved speeding
vehicles."
