What should you pay attention to when backing in a parking lot?

Answer: C — Position of entrances and exits

When backing in a parking lot, it is crucial to pay attention to the position of entrances and exits. Understanding the layout, including where you can enter and exit the parking lot, allows you to maneuver your vehicle more safely and efficiently. Being aware of these positions helps in planning your backing path, avoiding potential hazards, and ensuring that you don't block traffic flow. While other options might also seem relevant, focusing solely on traffic signals does not encompass the entire backing situation that may involve pedestrians, parked vehicles, or unforeseen obstacles. Similarly, while it is important to be aware of nearby pedestrians and available parking spaces, they are secondary to understanding the overall layout of the parking area. The entrances and exits dictate how you approach the maneuver and can significantly impact your safety and the safety of others around you.
