PROBLEM TO BE SOLVED: To provide a driving operation auxiliary device for a vehicle intelligibly transmitting the present risk and prospective risk of an own vehicle to a driver respectively. SOLUTION: The present risk and the prospective risk to which the own vehicle is confronted are calculated from a relative relationship of the own vehicle and a preceding vehicle and a position relationship of the own vehicle and a lane marker. When the present risk is high, a plurality of vibration elements at the positions corresponding to a generation direction of the risk are vibrated. When it is presumed that the prospective risk is high, the vibration elements to be vibrated are successively moved so as to promote driving operation in a direction avoiding the prospective risk.
