When should the interior lights of a school bus be activated?

Activating the interior lights of a school bus is essential for safety, particularly when loading or unloading students. This practice enhances visibility inside the bus, making it easier for both the bus driver and the students to see each other and navigate safely. When entering or exiting the bus, it is crucial for children to be aware of their surroundings, and bright interior lights can help reduce the risk of accidents in low-light situations or when visibility is limited.

When the interior lights are on while students are loading or unloading, it also helps ensure that drivers both on the bus and in other vehicles can better see the students' movements. This is particularly important as children can sometimes be less aware of their surroundings when they're excited or focused on getting on or off the bus. Thus, for optimal safety during these critical moments, turning on the interior lights is the appropriate action.
