I wanted as much data as possible so went back year after year to conduct more testing. Each time I got a
better picture of how the different types of instruments behave, some were brilliant, some useless, but at
least now I could explain why a Honda Jazz’s speedometer goes haywire in a crash. After 5 years of testing
(and still no budget), I had a comprehensive set of data covering all the types of crashes and instruments.
I wanted to replicate the forc-es
experienced in a real crash
rather than hitting the instru-ments
on a hard surface. They
were placed in different
orientations and also thrown
out of moving vehicles.
The testing took me to the USA where I started to look at the same phenomena but with motorcycles.
Any opportunity to take part
in a crash test was grabbed.
Some crash testing in Florida
resulted in impromptu data
being obtained and some
motorcycle instruments be-ing
smuggled back to the UK.
As the testing developed, I wrote up what we knew at each stage and spread the news to the wider
forensic collision investigation community. In 2013 I went to the European Association for Accident
Research and Analysis conference in Italy to present my latest findings. To my amazement, I won the
award for the best piece of research that year!
To date, I have conducted 130+ crash tests, produced 10 technical papers and presented across Europe
and the US. This has spawned further research papers by others.
Frozen Instrument Cluster Examination after a collision is now used worldwide and is accepted as part of
the Forensic Science discipline and is included as part of best practice in the Collision Reconstruction
Forensic Science of any discipline is still a relatively new science. Holes in our knowledge still exist, so
when we come across gaps in our knowledge don’t be afraid to let your inquisitiveness get the better of
