The Rear Collision Warning System (RCWS) for escort vehicles generally refers to a system installed on vehicles transporting dangerous chemicals or expensive special vehicles. During driving, sensors mounted on the rear of the vehicle detect the safe distance from the vehicle behind. When the vehicle behind approaches the rear of the vehicle, the sensors detect the risk of collision (less than the safe distance), and the system will emit audible and visual alarms to remind the vehicle behind to take measures and not to approach, so as to avoid rear-end collisions.
