Although it ceased to be a national requirement nearly 50 years earlier, in 1994 many UK
Police Forces were still collecting information about the factors which may have contributed
to the occurrence of a road traffic accident, the use of which, in conjunction with the more
objective STATS19 data, can make a vital contribution to road safety improvement. With the
aim of harmonising the quite divergent systems then in use, a new system for recording
these contributory factors was devised and tested by the Transport Research Laboratory
(TRL) in 1995. However, the use of this system proceeded on a voluntary basis after many
objections were raised by police and road safety practitioners. Eighteen police forces have
since adopted the TRL devised system. During this review, interviews were carried out to
assess current working practices and problems associated with the new and other systems.
This report summarises the findings from these interviews, together with a review of other
systems in use, and offers possible solutions to overcome the problems identified. A revised
system is recommended which retains many of the innovative ideas from the TRL designed
form, thus allowing a degree of continuity for those police forces who have already adopted
the system. It also overcomes many of the original objections raised, thus enabling
nationwide implementation.
