Abstract: In developing country accident is main cause of death. Growth in population has led to growth in technology. People use car on large number and number of accidents taking place, is increasing day-by-day. Road accidents are undoubtedly the most frequent happening cases and overall, the cause of the most damage The intensity of deaths are more in curved roads i.e mainly in U-turn, Hairpin bend roads and mountain narrow roads. In this case the driver can’t see the vehicle coming from the other side. Because of which thousands are losing their lives in accident. If the vehicle is in great speed then it is difficult to control and there are chances of falling off a cliff. Hence there is a need of many road safety systems. The solution for this problem is alerting the driver about the vehicle coming from the other side. This is done by keeping the sensor unit on one side of the road before the hairpin bend curve/Land Slide and keeping LED light after the curve/Landslide, so that vehicle coming from the one side of the road is sensed by the sensor unit and LED light glows at opposite side. By looking at the LED light driver become alert and slow down the speed of vehicle. When two cars pass from the opposite side of a mountain curve the sensor senses the car and LED colour changes to red and raises the buzzer giving signal of danger and then it changes one LED colour into green to allow the one car to pass and then the other LED colour turns green. In this way we can prevent the accidents of curved road. Once receive the signal from wireless module the vehicle reduce the speed by using motor drive unit.
