When should a driver ensure sufficient interior lighting during darkness?

Ensuring sufficient interior lighting during darkness is essential for the safety and well-being of passengers. The correct answer emphasizes that lighting should be adequate not only during passenger boarding but also for safe entry and exit from the bus at any time it is deemed necessary.

Good interior lighting allows passengers to navigate safely, reducing the risk of slips, trips, and falls as they move around the bus. It is particularly important when passengers are getting on or off, as well as when they might need to move around inside the bus for any reason, like finding their belongings or adjusting their seats.

Additionally, good lighting contributes to a sense of security for both passengers and the driver, as it allows for better visibility of all individuals on board, helping to prevent accidents and improve overall safety during nighttime travel. Therefore, the practice of ensuring sufficient interior lighting is not limited to specific situations, but rather should be a standard safety measure whenever it is dark and whenever passengers may require it.
