This paper deals with the impact phase of the vehicle-to-vehicle traffic accidents. Usually in this analysis, a two-dimensional rigid body collision theory is applied. Up to now, in collision theory, the vehicle was assumed to be a rectangular plate with sharp corners. In this assumption, however, singularity is included in the determination of the contact plane when the corner-to-corner collision occurs. In this paper, it is considered that the vehicle has round corners. Due to this consideration, the singularity is avoided, and the formulation of the vehicle corner-to-corner collisions becomes realistic and reasonable. Several results of corner-to-corner collisions are shown for comparison between the vehicles with round corners and right-angle ones. Then the vehicle velocities just after impact and vehicle trajectories are discussed.
