Zero-Speed Takeover displays ads when drivers ________?

Zero-Speed Takeover ads are designed to appear when a driver is safely stopped, ensuring minimal distraction. Specifically, these ads display when a driver comes to a complete stop for more than 4 seconds, such as at a traffic light or in heavy traffic. This timing allows drivers to view the ad without diverting attention from the road while in motion. The other options are incorrect because checking a phone is unsafe and not a Waze ad trigger, searching for a business triggers search ads, and beginning to drive means the driver is in motion, making ad display unsafe.
