A Collision Avoidance System is a technology designed to help vehicles prevent accidents by detecting potential collisions. It uses sensors, cameras, and radar to monitor the surroundings and identify obstacles, such as other vehicles, pedestrians, or road signs. When the system detects a possible crash, it can alert the driver with visual or audible warnings, and in some cases, it can even take automatic actions like applying the brakes. These systems are becoming increasingly common in modern vehicles, enhancing safety for everyone on the road. Many new cars now come equipped with features like automatic emergency braking and lane departure warnings, which are part of the broader category of advanced driver-assistance systems (ADAS).
