The collision avoidance system as a prototype, which avoids vehicle accidents and to provide a greatest security to the user in adverse or bad weather condition. Here, Ultrasonic sensor and IR sensors placed in the car, where IR sensor is used to detect the lane and avoids accident in significant manner. The vehicle state information is obtained using IR sensor, which will continuously track for any obstacle from front side. If the obstacle is closer to the car then the microcontroller will start applying the brake within the safe limit. A collision avoidance system consists of several sensors that are placed within a car which provide warning to the driver if there are any dangers that lie ahead on the road. These sensors include how close the car is to other cars, how much its speed needs to be reduced when obstacles closer to the car, how close the car going off the road, And the system consist of audio warning to prompt the driver, initiates braking if the driver fails to respond to the warning . Since the system consists of sensors which send and receive signals from other cars, obstacles on the road. A good example of the system is how it works when a driver is about to change lanes, and there is an obstacle in his blind spot. The sensor will detect that obstacle and give information to driver before him start turning his car, and prevent him from getting into serious accident.
