What distance must a student maintain from the bus while waiting?

Answer: C — 12 feet

The correct distance that students must maintain from the bus while waiting is 12 feet. This distance is crucial for safety reasons, as it provides a buffer zone to prevent accidents. Standing too close to the bus can increase the risk of being in the driver's blind spot and can create dangerous situations when the bus is moving or preparing to load and unload passengers. Maintaining a distance of 12 feet allows students to observe the bus and be aware of their surroundings while keeping themselves safe. Distances shorter than this might not provide adequate safety and could put students at risk of injury, especially when they are getting on or off the bus. It's essential for students to be well-informed about these guidelines to ensure their safety while commuting.
