In this paper, the authors' deal with automatic detection of red light traffic signals or vehicle speed limit signs on roads by using RFID technology to control an automobile. In the present scenario traffic violations are increasing rapidly. It gives rise to major problems which are beyond human control directly and therefore there is a need for automation. An RFID reader present in the vehicle senses the active RFID tag (which is linked with a red traffic light to turn it on or off) or senses the vehicle speed limit on the tag as a reference speed input (attached to the speed limit signboard).
