Nowadays the maximum number of cars have a high level of automatic safety system which help driver to maintain control of car and their safety system warn the driver of any potential danger. Car safety is increased by these types of distinctive attributes, but they are expensive and can be found only in expensive cars. Our research paper focuses on making a forward collision mitigation system that can work in all Kinds of vehicles without making any kind of differences between them because of Age, make, model or type and can be affordable at minimum price. If two vehicles are Moving on the same road and in the same direction, the system will analyse the distance Between two vehicles, then warn the driver about any potential danger in which she or He can be in by using ultrasonic sensors and a microcontroller. To alert the driver and Passengers effectively, the distance between two vehicles is calculated by an audio-Visual alarm and an ultrasonic.
