Abstract: A method for displaying positions of vehicles, may include receiving, by a control unit, position information of a first vehicle via a Global Navigation Satellite System (GNSS) receiving unit; when the position information of the first vehicle is normally received, judging whether there is a second vehicle in a reference distance from the first vehicle via the V2X module; when there is a second vehicle in the reference distance from the first vehicle, collecting vehicle information relating to the second vehicle via the V2X module; and displaying the positions of the first vehicle and the second vehicle to an output unit based on the position information of the first vehicle and the vehicle information relating the second vehicle.
