Which lighting requirements should passenger vehicles with a capacity of more than 12 persons follow?

Passenger vehicles with a capacity of more than 12 persons, such as buses or larger vans, have specific lighting requirements to ensure the safety and comfort of all occupants. One important requirement is that the lights must illuminate the passenger aisle. This ensures that passengers can safely navigate the interior of the vehicle, especially in low visibility conditions or during night travel.

Additionally, it is mandated that interior lights be on between sunset and sunrise. This requirement helps in creating a well-lit environment within the vehicle, making it easier for passengers to see their surroundings and reducing the risk of accidents during entry and exit when external light may be minimal.

Both of these conditions are aimed at enhancing safety for passengers, particularly those who may need assistive navigation due to limitations in visibility. While keeping all interior lights on at all times might seem like a reasonable approach, it is unnecessary and could create distractions or issues with vehicle battery life. Thus, the combination of illuminating the passenger aisle and activating interior lights during darker times is the correct interpretation of the lighting requirements for these larger passenger vehicles.
