Final answer:
When backing in a parking lot, one must pay attention to the position of the entrances and exits for safe maneuvering and accident prevention.
Step-by-step explanation:
When backing in a parking lot, it is important to take note of the position of the entrances and exits. This is because being aware of the surroundings, including the location of other vehicles, pedestrians, and obstacles, is crucial for preventing accidents and ensuring safe maneuvering of the vehicle. Factors such as the location of the sun in the sky, the amount of fuel in the tank, and the reading on your tachometer, while important for other aspects of driving, do not directly influence the immediate safety concerns when backing up in a parking lot.
