The RCTA ADAS system, which means "Rear Cross Traffic Alert", is a driver assistance technology that forms part of ADAS (Advanced Driver Assistance Systems). This function is designed to alert drivers to vehicles approaching from the sides, especially useful when reversing in places such as car parks or driveways where visibility is limited.
