What is the purpose of the "no zones" around a bus?

Answer: B — Areas where a driver cannot see other vehicles

The purpose of the "no zones" around a bus relates to areas where a driver cannot see other vehicles. Buses have significant blind spots on all sides, particularly on the front, rear, and sides, which can make it difficult for the bus driver to detect vehicles, pedestrians, or cyclists in these areas. These "no zones" are crucial for safety, as they help to highlight the limitations of a bus driver’s visibility. Understanding and recognizing these zones can help other road users stay clear of these blind spots, reducing the risk of accidents. It's important for both bus drivers and other road users to be aware of these no zones, promoting better safety for everyone on the road.
