Under what circumstances can you send text messages while driving your bus?

The option indicating that no circumstances allow sending text messages while driving a bus is the correct choice because safety regulations are designed to minimize distractions for bus drivers. Operating a large vehicle, such as a bus, requires full attention to the road and surroundings to ensure the safety of passengers, pedestrians, and other vehicles.

Text messaging involves taking your eyes off the road, even for a brief moment, which significantly increases the likelihood of an accident. This is particularly critical for bus drivers who are responsible for transporting multiple passengers safely. Therefore, any form of texting while driving, including at stoplights, low speeds, or when communicating with a depot, is prohibited to maintain maximum focus on driving tasks.

Options suggesting that texting is acceptable in specific scenarios misunderstand the importance of consistent attention while operating a vehicle. The governing laws and regulations prioritize road safety, emphasizing that drivers must be fully engaged in their driving responsibilities at all times.
