Which of the following is NOT listed among the top 5 Advanced Safety Systems?

• A. Automatic Emergency Braking
• B. Forward Collision Warning
• C. Lane Departure Warning
• D. Rear Cross-Traffic Alert

Answer: (D)

Focusing on the main idea: which features are considered the core crash-prevention tools in modern vehicles. Automatic Emergency Breathing? No—Automatic Emergency Braking actively slows or stops the car to avoid a collision, and Forward Collision Warning alerts you to a looming crash. Lane Departure Warning detects when you drift out of your lane. Together these represent proactive safety functions that directly intervene in preventing crashes or reducing impact. In most top-five lists, the remaining spots are filled by other proactive systems like Lane Keeping Assist or Adaptive Cruise Control, which help maintain lane position or a safe following distance.

Rear Cross-Traffic Alert, while highly useful for awareness—especially when backing out of a driveway or parking space—is more about detecting cross traffic rather than actively preventing a frontal collision. Because the top five emphasize preventive, intervention-focused systems, this feature isn’t typically counted among them. That’s why Rear Cross-Traffic Alert isn’t listed in the top five.
