Abstract: Vehicle-to-Vehicle (V2V) communication is a key technology in Intelligent Transportation Systems (ITS), enabling vehicles to share real-time information such as speed, braking, and hazard warnings. Unlike conventional sensors limited by line-of-sight, V2V enhances cooperative awareness to reduce accidents, improve traffic flow, and optimize fuel efficiency. This paper presents the design of a low-cost prototype using Arduino Uno, ultrasonic sensors, tilt sensors, and HC-12 wireless modules, supported by an LCD, buzzer, and regulated power supply for driver alerts. The system detects obstacles, monitors driver attentiveness, and transmits warnings within a 1 km range. While the prototype shows feasibility for affordable deployment, challenges such as limited range, security, and standardization must be addressed. Future integration with 5G, C-V2X, and AI-based traffic management can further enhance safety and scalability.
