What does the 2025 QX55's Rear Cross Traffic Alert (RCTA) help the driver detect when backing up?

The 2025 QX55's Rear Cross Traffic Alert (RCTA) is designed to assist drivers by alerting them to other vehicles that are approaching from the sides while the vehicle is in reverse. This feature enhances safety by detecting vehicles that may be moving towards the rear of the vehicle in parking lots or when backing out of driveways. The system typically utilizes sensors to monitor cross traffic and provides visual and/or audible alerts to warn the driver of potential collisions, thereby increasing the driver's awareness and ability to react promptly to avoid accidents.

The purpose of this system is specifically focused on detecting moving vehicles, making it particularly vital in situations where visibility might be limited and the driver may not be aware of incoming traffic from the sides. Other options like detecting nearby pedestrians, obstacles directly behind the vehicle, or traffic signals do not directly align with the primary function of RCTA.
