In order to keep a highly safe and reliable system of car driving, it is important that the system would be considered as a man-machine system including not only the feature of vehicle movement but also human perception, cognition, and motion of a driver. In this paper, it is examined to clarify the relation between feature of eye movements and driving behavior in conventional and unconventional situation by the experiments using the driving simulator and the eye tracking system. The measurements of time histories of eye movements were performed in the situation of different traffic regulation by the simulator. It is recognized in both turns that typical patterns of eye movements in horizontal axis appeared between the start and end of the turns. It is found from the time histories of eye movements by synchronizing that of vehicle data that the appearances of fixations were distributed uniformly on the trajectories of vehicle by trained drivers from the start of turning to the end, while the appearance of fixation by untrained drivers are concentrated in the beginning of turning or the end. These facts mean that the untrained driver did not receive visual information during the operation of turning, therefore the trajectories of vehicle by untrained driver showed the overshooting in the right turn and undershooting in the left turn.
