The road specifically includes a special roadway such as a carpool lane having no exits to other roads, an ordinary roadway having exits to the other roads and a predetermined traveling-path changing area provided as a sole area allowing a vehicle to change a traveling path thereof between the special roadway and the ordinary roadway. The apparatus determines a present position of a vehicle, determines whether the detected position is in the special roadway or in an ordinary roadway. The apparatus provides, in addition to normal travel guidance, information on the traveling-path changing area existing ahead of the vehicle on a display, when the detected position is in the special roadway.
