Actions to prevent or to reduce the severity of trucks rollover in general and tank trucks in particular, constitute a permanent research subject worldwide. In this context, researchers at the University of Michigan Transportation Research Institute (UMTRI) carried out simulations aiming to characterize the mechanics of tank trucks rollover and the consequences on tank truck container deformation, proposing needed standards concerning the impact velocity that containers should withstand. However, no attention was explicitly paid in this study to the exact location of the first strike point on the container during rollovers. In this paper, UMTRI simulation results, are used to characterize the tank surface region on which the first impact occurs, when a rollover happened, and the associated severity. Results indicate the concentration of the first impact event and severity on certain surface areas of the container, located at the upper portions of both container ends (front and rear). With this information, different design schemes could be proposed to increase the kinetic energy absorption of such vulnerable surface regions, thus reducing the rollover severity.
