How must baggage or freight carried on a bus be secured?

The correct answer emphasizes the importance of ensuring that baggage or freight carried on a bus is secured in a way that allows for safe and quick access to emergency exits. By ensuring that baggage does not obstruct any doors or windows, passengers have an unobstructed path to evacuate the bus in the event of an emergency. This consideration is critical for passenger safety, as it minimizes the risk of injury or panic during situations where every second counts.

Effective baggage management includes positioning items so they do not block exits while still being secured, ensuring they don't become hazards that could impede evacuation efforts. This approach not only protects passengers but also aligns with safety regulations governing the transportation of individuals.

Other choices may seem plausible but can create safety concerns. Keeping baggage in a separate compartment is beneficial but may not address the need for accessibility in emergencies. Placing items in front of the standee line could create obstacles, while allowing baggage to be loose but out of the walkway won’t guarantee a clear evacuation route in a crisis. Hence, the correct focus is on maintaining clear access to exits to enhance passenger safety.
