Which lighting requirement applies when a bus operates on public streets after dark?

When operating a bus on public streets after dark, all interior bus lights should indeed be on to ensure passenger safety and visibility. This adherence to proper lighting enhances the overall safety of both passengers and drivers by allowing everyone to see and move around safely within the bus. Proper interior lighting is also crucial for helping passengers find their seats, read signs or help them in emergencies.

Moreover, while headlights and exterior lights are essential for the visibility of the bus to other drivers, interior lights play a vital role in the comfort and safety of those inside the bus. Ensuring that all interior lights are operational demonstrates a commitment to passenger safety and enhances the overall travel experience. This requirement underscores the importance of visibility not just for the vehicle's operation but also for the safety of those on board.
