The utility model relates to a vehicle state notifying device, which is a state notifying device which is used to notify the operating state of a vehicle, and comprises a detection device which is used to detect the state of waiting for driving, a sound-producing device which can periodically produce the stated musical sound, when the vehicle is in the state of waiting for driving, and a display device which can periodically change to display. The display cycle of the display device is synchronous with the producing cycle of the musical sound. When a vehicle is in the state of waiting for driving, the vehicle state notifying device periodically produces the stated musical sound. When the musical sound is produced, the vehicle state notifying device produces the display cycle which is synchronous with the cycle produced by the musical sound. So the vehicle state notifying device displays in the display mode of periodic change. In other words, the standby state of the vehicle is notified in the notifying mode of the corresponding auditory sensation and the visual sensation. When the state of waiting for driving is notified in the modes of visual sensation and auditory sensation, passengers can know that the vehicle is in the state of waiting for driving by intuition.
