Why is it important to secure cargo on a bus?

Answer: B — To prevent shifting and ensure passenger safety

Securing cargo on a bus is essential primarily to prevent shifting, which directly enhances passenger safety. When cargo is properly secured, it minimizes the risk of items moving during transit, particularly during sudden stops or sharp turns. Unsecured cargo can become a projectile, posing a serious hazard to passengers and drivers alike. Additionally, in the event of an accident, secure cargo can help prevent injuries or fatalities that might arise from shifting loads. While making room for more passengers might seem convenient, it does not address the safety concerns associated with unsecured items. Inspection fines are certainly a relevant factor in overall fleet management and compliance, but these do not directly relate to the immediate safety of passengers. Fuel efficiency is also important for operational costs, but it is secondary to ensuring a safe and stable environment within the bus. The primary objective should always be passenger safety, which is why securing cargo is a critical responsibility for drivers and operators.
