A navigation device (100), which is an electronic device, monitors the positions and the speeds of a preceding car and a host car by an image pickup device (201), a sensor (202), a detection unit (102), a vehicle-speed sensor (103), a GPS unit (104), a control unit (105), and calculates the current speed of the preceding car, distances from the preceding car to an intersection with a traffic light located ahead of the host car and the preceding car in the traveling direction thereof, and the timing when the traffic light changes based on traffic signal information received by a signal reception unit (101). The control unit (105) predicts whether or not the preceding car can stop before a stop line position located before the intersection without braking suddenly when the traffic light changes to a red signal display state at the timing when the host car receives the traffic light information and at the timing when the traffic light changes to a yellow signal display state. When the control unit (105) predicts that the preceding car cannot stop without braking suddenly, the control unit (105) warns the driver by using a display unit (109) and a sound output device (203) to prevent a collision. By predicting the stop of the preceding car as described above, the risk that the host car could bump into the preceding car can be prevented.
