Abstract- As the number of vehicles increasingday-by-day, accidents are also increasing rapidly. These accidents can be dueto false estimation of nearby vehicles, disturbances in mind of driver or anyreasons due to which driver can’t keep focus on driving. The project is basedon the accident. This system can measure the distance between the driving car andfront object and can calculate the safety distance of driving car based on itscurrent speed. If driver doesn’t keep the minimum safety with front object, itwill warn the driver to slow down the speed of car to avoid collision. And ifthe driver doesn’t slow down the car, this system will automatically slows downand stop the car before the collision could occur.
