There is provided a vehicle interference prevention device that, by computing a range of possible locations of a vehicle taking into consideration the time at which the location of the vehicle is measured, can safely predict the location of the vehicle, even with minimal frequency of radio contact, and prevent interference among unmanned vehicles or manned vehicles over the entirety of large work site. An unmanned vehicle uses the latest position data for a manned vehicle acquired (received) via an inter-vehicle communication device to determine a position (position at a certain point in time) as the basis for computing a circle having this position as its center and having a radius equal to the distance traveled at maximum speed from this point to a predetermined future point in time, and designates the area within this circle on a prearranged travel route as a range of possible locations for the manned vehicle. The unmanned vehicle then decides whether its own vehicle position interferes with this circle.
