Yaw natural frequency is employed as an index of vehicle dynamic behavior. A yaw natural frequency taken in account of roll motion has been formulated. On the other hand, a mode of yaw natural frequency was studied in recent years. As a result of that, it was clarified a difference between the resonant mode and supposed condition for the formulating. Therefore this paper formulated yaw natural frequency based on the mode. As a result of that, it was clarified that the former formula of yaw natural frequency was taken in account of excessive roll motion and normal the load distribution affects yaw natural frequency.
