The Vehicle forensic Department of the Institute for Criminal Research of the French Gendarmerie Nationale (Institut de recherche criminelle de la gendarmerie nationale – IRCGN) comprises three expertise units named: Mechanical Identification, Chemical identification and Accidentology. The latter is mainly in charge of the vehicle identification during a criminal case and the accident analysis during civil cases. When analysing road accidents, it is useful and sometimes necessary to read into the potential forensic traces, in order to built accident scenarios hypothesis. The IRCGN vehicle service is specialised in the analysis of such traces which are the reminisence of the vehicle interaction with its environment and its driver. To illustrate this approach, automotive paint systems and their caracteristics will be presented. Different polymers analysis techniques will be exposed: Optical microscopy, pyrolysis, gas chromatography, spectrometry,infra red and Raman spectroscopy.... These techniques can identify nearly all automotive polymers, including paints. Other traces analysis examples will be presented: clothes, tyres.... Matter transfer (simple or crossed) will be treated as well because through them vehicle types (even vehicle itself) can be identified and links can be established between the three different components (Human, Vehicle and Environment) of a Road Accident.
When dedicated to the criminal forensic traces potential, these approaches are pertinent to establish road accident scenarii and then reconstruct the occurence.
