What is the minimum distance that school bus warning lamps must be visible?

The correct answer indicates that school bus warning lamps must be visible from a minimum distance of 500 feet. This distance is critical for ensuring safety on the roads, especially around school zones where children may be boarding or disembarking from school buses. The visibility requirement helps to alert drivers well in advance that they are approaching a stopped school bus, allowing them to take necessary precautions and reduce speed.

This regulation is part of broader traffic safety measures designed to protect children, as drivers need ample warning to respond appropriately when encountering a school bus with activated warning lights. Ensuring that the warning lamps can be seen from such a distance contributes significantly to preventing accidents and enhancing overall road safety in areas where children are present.
