The present invention widely and speedily shares safety information even when wide area networks are halted during a disaster or the like. A safety information transmission method includes a step wherein a first portable terminal (103) transmits the safety information to the vehicle-mounted terminal (101), a step wherein the vehicle-mounted terminal (101) stores the safety information received from the first portable terminal (103), a step wherein the vehicle-mounted terminal (101) transmits the safety information to another vehicle-mounted terminal (101) by a vehicle-to-vehicle communication, a step wherein the vehicle-mounted terminal (101) stores the safety information received from the other vehicle-mounted terminal (101) by the vehicle-to-vehicle communication, and a step wherein any of the vehicle-mounted terminals (101) transmits the safety information stored in the vehicle-mounted terminal to an information server (113) via an access point when the vehicle-mounted terminals (101) has reached a communication possible area of the access point, or transmits the safety information stored in the vehicle-mounted terminal (101) to a second portable terminal (103) when the vehicle-mounted terminal has become capable of communicating with the second portable terminal (103).
