Abstract
Traffic accident expertise quest for the reconstruction of an event dynamics. In this way, the present work introduces a new approach in “frozen speedometer” analysis, enlarging the perspective of knowledge and evidence reading by the expert. Engine rotation is a valuable parameter, because it allows to face the velocity during the collision with the one presented by the vehicle speedometer. A case report is depicted to the reader, in a practical way, as a guide to correlate the event cinematic variables, granting him to calculate the traffic units’ velocity, contributing for the recreation of extreme complex dynamics.
