The present invention discloses a system that alerts to the operator ol a vehicle, when a particular vehicle operator is
not in the course of slowing down to stop a vehicle traveling towards an intersection, in particularly when said vehicle moving direction intersection traffic light condition turns ember and or red. Or where an intersection requires all or particular direction travel vehicles to make a full stop before said vehicles cross said intersection, to avoid intersection vehicle collision. The system comprises of traffic light or stop sign RF transceivers units, and plurality of vehicles equipped with vehicle transceivers units to communicate with said intersection traffic signal transceiver units. And said vehicle transceiver unit is equipped with vehicle speed sensors comparator CPU and vehicle movement direction detecting sensor circuitry, using transponder reader, compass or GPS receiver to detect vehicle direction movement, and to detect signal light condition along with monitoring vehicle speed. If a vehicle operator after receiving said warning signals at a predetermined time does not maintain vehicle speed in compliances with said traffic signal light condition, the vehicle mount speed comparator CPU will alert the pedestrians, other vehicle operators located within said particular intersection with an audio-visual or vibrating alarm signals. And upon said vehicle passing said intersection wile said traffic direction signal condition indicating an stop condition, said vehicle speed comparator CPU transmits said violation signal to a monitoring station with information containing to the particular vehicle and it's operator. Said monitoring station is equipped with a computer database connected to an Internet or intranet.
