This paper presents an innovative approach to Vehicle-to-Vehicle (V2V) communication utilizing Light Fidelity (Li-Fi) technology. Effective communication between vehicles is essential for reducing auto accidents and serves as a crucial component of intelligent transportation systems. Traffic accident detection has emerged as a critical area of focus due to its significant role in improving road safety. This study explores advanced accident detection mechanisms using Li-Fi technology, providing a sophisticated solution to enhance human safety by preventing accidents. The proposed system integrates multiple sensors, including ultrasonic and alcohol detectors, to monitor and respond to various scenarios. When vehicles are in close proximity, the system alerts the driver of the vehicle ahead, ensuring increased driver awareness and promoting safer driving conditions.
