Opportinities offered by advanced technology to address collision avoidance are rapidly becoming a major focus of highway safety research. The understanding of the traffic situations in which collisions occur is needed to guide this research towards effective applications. This paper focuses on the most frequent car fatal precrash scenarios in terms of car kinematics. A typology containing 74 of these scenarios was developed which includes the number of vehicles involved, road characteristics and car trajectories. This typology is applied to 4,298 fatal car occupant crash police reports recorded over one year in France. 74% of cases are related to the failure of the driver in his/her interaction with the road infrastructure and 24$ in his/her interaction with the traffic. Results on yawing rate and driver perception and reaction in these circumstances are also given.
