Abstract: Nowadays most of the Accidents on Highways are because of Weak security systems in the vehicles. since there is no proper alerting system when the nearby vehicle approaching the ongoing vehicle this leads to moreAccidents. This project demonstrates a highway vehicle security system with an alerting signal and Buzzer. When any vehicle approaches the rear window of the vehicle it glows a bright LED with buzzer and It will glow until the vehicle over takes. And there will be a signal to indicate and gives buzzer for safe highway driving. The light automatically emits and gives a buzzer when the approaching vehicle reaches less than the set distance and it will alert the driver even during the day , giving additional safety during night and when a vehicle at rest......
