Which item is prohibited from being carried onto a bus during transport?

Carrying car batteries onto a bus is prohibited due to several safety concerns. Car batteries contain hazardous materials, including sulfuric acid and lead, which can pose a significant risk to passengers and crew if a leak or spill occurs. Additionally, car batteries can produce hydrogen gas, which is highly flammable, creating a fire hazard in the confined space of the bus.

In contrast, emergency medical supplies, small pets (depending on the bus company's policy), and snacks and beverages are generally allowed, as long as they do not compromise the safety and comfort of other passengers. It's important for all bus operators to maintain a safe environment, which is why certain items like car batteries are categorically restricted. Understanding these safety regulations is crucial for both drivers and passengers on public transport.
