Rear cross-traffic alert is a safety feature found in many modern vehicles. Its primary function is to warn the driver of approaching vehicles when the car is in reverse. This is particularly useful when backing out of a parking space, especially in situations where visibility is limited, such as between two large SUVs or in a busy parking lot.

The system typically utilizes sensors, often radar or ultrasonic, located in the rear bumper of the vehicle. These sensors scan the areas to the left and right of the car, perpendicular to the direction of travel. When an object, such as another vehicle, a pedestrian, or a cyclist, enters the detection zone while the car is in reverse, the system activates.

The alert is usually conveyed to the driver through a combination of visual and auditory cues. Visual warnings might appear on the infotainment screen or the rearview mirror, often highlighting the direction from which the hazard is approaching. Auditory alerts can range from beeping sounds to specific chime notifications. Some advanced systems may also integrate with the vehicle's braking system, automatically applying the brakes to prevent a potential collision if the driver does not react in time. Rear cross-traffic alert significantly enhances driver awareness and contributes to safer maneuvering in reverse.
