It’s almost 2 weeks until the largest reconstruction conference in the world. WREX, the World Reconstruction Exposition is being held in Orlando, Florida.  You can find the full details at

WREX2016 will be the first World Reconstruction Exposition that has been held since the year 2000. The event is being sponsored by 21 crash associations from the US, Canada, and around the world. WREX 2016 IS the largest training event for crash investigators that has ever been held.

This is a rare event. The next WREX event is not planned until 2025!

I am delighted to say that I have been invited to WREX2016 as one of the guest lecturers.

The subject for my lecture is how speedometers behave during a collision. The lectures are based on eight years of research. The phenomenon of a speedometer and indeed all the gauges within an instrument cluster to apparently lock and freeze at the moment of impact depends on two principle factors. Firstly that the impact must cause the lost of electrical power to the instrument and secondly that the electronic stepper motor used to drive the needle must hold the position of the needle during the shock of the impact.

We have produced a set of criteria to help ensure the principles apply.

As it happens some collisions are excellent at having the right conditions to produce a reliable frozen position while other are quite frankly useless.

It’s the ability to test and determine when to accept or reject the reading that is the subject of the presentations in Florida.

To date the research has produced some excellent results and in 2013 I won an award from the EVU (, the European Association for Accident Research and Analysis for the best research paper.

I am very much looking forward to meeting fellow reconstruction experts from around the world.
