What must not be worn while operating buses?

When operating buses, it is crucial for safety and focus that operators do not wear or use a cell phone. Cell phone use can be highly distracting, diverting attention away from the road and increasing the risk of accidents. This prohibition is grounded in the necessity for bus operators to maintain full concentration on driving and the passengers, as any distraction could lead to dangerous situations or service disruptions.

Other options, such as safety gloves, sunglasses, and reflective vests, are either encouraged or necessary for safety, as they can help enhance visibility and protect the operator while ensuring safe operation of the vehicle.
