Abstracts: ? Nowadays people are driving very fast, accidents are occurring frequently, we lost our valuable life by making small mistake while driving (school zone, hills area, highways). ? So in order to avoid such kind of accidents and to alert the drivers and to control their vehicle speed in such kind of places the highway department have placed the signboards. But sometimes it may to possible to view that kind of signboards and there is a chance for accident. ? This project is developed based on EMBEDDED and RF Technology. ? Every zone like school, highway and etc may have a transmitter tag to transmit the zone information by RF signal and a RF receiver in the vehicle to receive information ? When a vehicle enters a Danger Zone then the signal will be detected by the Rx which was transmitted by the TX placed in the Zone. ? The Signal received will be decoded by the microcontroller and alert the driver through a LCD Screen. ? According to signal received by Microcontroller controls the DC Motor Speed after a few seconds from the time it received the signal. ? An actuator control the throttle of the vehicle
