Abstract
A method of providing a warning about a vehicle in violation of a traffic signal includes: transmitting, by a rear vehicle driving behind a front vehicle entering an intersection in a first direction, signal violation information to a nearby vehicle entering the intersection in a second direction different from the first direction through vehicle-to-vehicle (V2V) communication when the rear vehicle determines whether the front vehicle is in violation of a traffic signal at the intersection using sensing information obtained by sensing the front vehicle and determines that the front vehicle is in violation of the traffic signal; and generating, by the nearby vehicle, a warning about a risk of collision with the front vehicle using the signal violation information transmitted from the rear vehicle.
