An abnormality notification device in a vehicle determines contents of situation information received from a second vehicle as abnormal at a certain timing. Then, the vehicle transmits abnormality information including identity information of the second vehicle to a station at a next timing, and transmits at a yet next timing a report completion notice notifying a nearby vehicle of the identity information of the second vehicle regarding which the abnormality information has already been transmitted to the station. When the nearby vehicle detects the second vehicle at still yet next timing as an abnormal vehicle, the nearby vehicle refrains from transmitting the abnormality information of the second vehicle at a subsequent timing, since the nearby vehicle has already received the report completion notice from the vehicle at the yet next timing. As such, unnecessary communication between a vehicle and a station is suppressed, and frequency utilization efficiency is improvable.
