Rear Cross Traffic Alert is a safety feature in many modern vehicles designed to help drivers when reversing. It uses sensors to detect approaching vehicles from the sides while backing out of parking spaces. If a vehicle is detected, the system alerts the driver with visual and audible warnings. This technology enhances safety by reducing the risk of collisions in busy parking lots or driveways. By providing an extra layer of awareness, Rear Cross Traffic Alert helps drivers make safer decisions when maneuvering in reverse, especially in situations with limited visibility.
