Car accidents involving heavy traffic are a significant international issue, with about 1.19 million fatalities each year. In third world countries such as India, it is more serious because of the low visibility of the night, the slow emergency response, the inability of cars to move, and the inability to have the modern safety systems. Such challenges show that it is necessary to have a smart and connected solution which will be capable of preventing accidents as well as acting swiftly when they happen.

The paper suggests AUTONEX, a free electric vehicle safety system created with the help of the Internet of Things (IoT) technology to make the road safer and operate more efficiently. The system will combine numerous synchronized units: (1) an obstacle detection device based on an ESP32-CAM to observe and avoid collisions in real time, (2) a smart headlight dimming to minimize glare on the road at night, and (3) an alcohol-detection system to ensure safety in the use of a vehicle. This system also incorporates    (4) the accident detection and emergency communication unit based on GSM and GPS to exchange data in real-time and share locations to achieve quicker responses to rescue. Also, it features (5) a solar-powered charging module, which is activated under low battery conditions to enhance the efficiency of energy. (6) A battery control system can be used to provide stability of power and reliability. The suggested system offers an efficient method of addressing the emerging transportation systems of the next generation by offering a comprehensive approach in accident prevention, pinpointed energy regulation, and instant emergency response.
