Which of the following emergency equipment is required on a bus?

The correct answer is based on specific regulations regarding the mandatory equipment that must be present on a bus for emergency situations. A fire extinguisher is crucial for any vehicle, especially a passenger bus, to address potential fires promptly and effectively. Spare electric fuses are important for maintaining electrical systems in case of failures, ensuring that essential lights and other electric functionalities remain operational during emergencies. Reflectors are essential for alerting other drivers to the presence of a stationary bus, particularly at night or in low-visibility conditions.

Each of these items plays a significant role in enhancing safety and ensuring that the bus can be used effectively in various emergency situations. Therefore, the combination of a fire extinguisher, spare electric fuses, and reflectors provides a comprehensive set of equipment that aligns with safety regulations and best practices for passenger buses.
