The present invention relates to an emergency alert and warning apparatus and, more particularly, to a road emergency alert and warning apparatus which is installed on a median strip or a guide rail of an expressway or the like to alert a driver of a rear vehicle of an emergency situation when a traffic accident occurs during nighttime driving, thereby preventing an additional secondary accident. According to an embodiment of the present invention, the emergency alert and warning apparatus comprises: an operation switch which is installed on a median strip or a guide rail of a road to allow a user to generate an operation signal when a traffic accident occurs; a control unit which receives the operation signal to output a control signal, and transmits or relays traffic accident notification data to another neighboring emergency alert and warning apparatus through a wired or wireless communication; a warning display unit which is installed rearward with respect to a traveling direction of a vehicle and includes a plurality of LEDs that are turned on and off in response to the control signal of the control unit; and a photovoltaic cell which converts solar energy into electric energy, processes the electric energy into a constant voltage through a DC/DC converter, and supplies power.
