A running vehicle alerting system, comprising one or more forwardly directed optical sensors mounted on a same vehicle which are configured to capture road related images; an image processing unit configured to analyze the captured road-related images in real time and to determine, based on the analyzed images, whether the vehicle on which the one or more optical sensors are mounted is to be considered as a running vehicle that is spaced from a traffic light or a traffic sign by a distance shorter than a threshold safe braking distance and that is liable to endanger other vehicles; and an alert signal generating unit responsive to the determination of the vehicle as a running vehicle, for generating a collision avoiding alert signal.
