New IAM report on incident causality

Postby tfdodo » Fri Apr 15, 2011 5:32 pm

lifted shamelessly from the AIRSO newsletter [seems fair as its from our parent organisation anyway]:

Driver and rider error or reaction is behind the top three causes of fatal and serious crashes according to the latest research by the IAM. Cars don’t lose control; drivers do.

The publication “Licensed to skill” - Contributory factors in Accidents - presents the analysis of five years worth of data, recorded by the police between 2005 and 2009.

Whilst there are no surprises in many respects with the findings it will be of interest to see what actually does not appear in the top ten rather than what does and this ought to be a strong indicator given reduced resources of just where effort ought to be placed in casualty reduction terms. Using a mobile phone whilst driving for instance may well be a major distraction which evidence supports but when it comes down to the reality of what is actual causing crashes it insignificant and in fact the messages from the report are much simpler than we think.

Factors including ‘failed to look properly’ ‘loss of control’ and ‘poor turn or manoeuvre’, accounted for 65.3 per cent of fatal, 61.8 per cent of serious and 68.6 per cent of slight collisions. Injudicious action - illegal or unwise judgements – such as exceeding the speed limit, following too close, or making an illegal turn, was the second biggest factor, accounting for another 31.4 per cent of accidents.

Alcohol was a relatively minor factor, listed in only ten per cent of fatal incidents.

Behaviour or inexperience came a close third, being a factor in 28.0 per cent.
In contrast, physical circumstances such as road environment, factors affecting vision, and vehicle defects are listed as issues in very few.

‘Travelling too fast for the conditions’ accounts for more fatal crashes than ‘exceeding speed limit’ which represent fourth and fifth places.

Driving too fast isn’t necessarily just a case of a legal requirement – you could be driving too fast for the conditions, without breaking any official speed limits at all.
