What does the 2025 QX55's Rear Cross Traffic Alert (RCTA) assist the driver in detecting when backing up?

The Rear Cross Traffic Alert (RCTA) system in the 2025 QX55 is designed to enhance safety by alerting the driver to other vehicles that may be approaching from the sides while they are in reverse. This feature is particularly useful in parking situations or when backing out of driveways where visibility can be limited. By detecting cross traffic, the system helps prevent potential accidents by notifying the driver of vehicles that may be passing behind them, allowing for safer maneuvering.

The other options, while related to driving scenarios, do not capture the specific functionality of the RCTA. Obstacles directly behind the vehicle, pedestrians, and nearby cyclists are generally detected by other systems or technologies within the vehicle that focus on immediate surroundings rather than the cross traffic approach.
