What is one of the regulations regarding the operation of buses?

The requirement that buses cannot be operated without a fire extinguisher is an important safety regulation. Fire extinguishers are critical safety equipment designed to help drivers and passengers respond to potential fire hazards that may arise during operation. In many jurisdictions, it is mandated by law that commercial buses must carry appropriate fire extinguishers that are easily accessible and meet specific standards, ensuring that in the event of a fire, appropriate measures can be taken quickly to protect the lives of those on board and minimize damage to the vehicle. Ensuring compliance with such safety regulations is vital for the responsible operation of public transportation vehicles.

The other options do not align with established operational regulations. For instance, buses must be registered and are typically required to have their headlights on during the day in many areas to enhance visibility and safety. Monthly inspections, while important for maintenance and safety, may not be a universal requirement; inspection frequency can vary based on local laws and operational guidelines.
