Abstract: Our mainly concentrated on the concept of accident prevention and obstacles detection. Heavy vehicle drivers in the highways can expect unexpected threats in the pathway unexpected threats in the pathway which may be even turn out to be fatal. Always a human eye could not be trusted to find out the obstacle that the vehicle is going to face during the travel so we have developed a protype which could detect the obstacles without considering its size using the help of ultrasonic sensor and the groove coupler to measure the distance between the vehicle and the obstacle. If obstacle is find it give an alert or automatic break system is applied.

Keywords: Obstacle detection, accident prevention, alert and automatic break system.
