Every day we hear news of accidents from every news service, and even with all the technologies out there, accidents still happen, today vehicle accidents are the leading cause of death and disability. The World Health Organization (WHO) estimates that around 4000 people die in road accidents in a single day, with more than 15% of these deaths in India, and many accidents go unreported. We are facing huge loss of life and damage to vehicles. Thus, to avoid any problem, we propose a system based on the ESP32s microcontroller, using an ultrasonic sensor to measure the distance between two vehicles, when the distance is less than a given threshold distance, by activating the so-called buffer parameter mean-while automatically controls the vehicle speed. A pre-safety measure to prevent accidents. This avoids the risk of collision due to speed, and our system also uses a blink sensor to warn the driver when the persons feel drowsy while driving. This system aims to provide at most care and precautions to both users and vehicles, ultimately reduces the chance of accidents occurrence and saves the lives of people who died because of road accidents.
