If no lookout is available, what is your best option?

When no lookout is available, the best option is to walk to the rear of the bus yourself. This action allows you to assess the situation directly, ensuring that it is safe to back up the vehicle without obstruction. Walking to the rear provides a clear visual of the area behind the bus, which is crucial for preventing accidents and ensuring the safety of pedestrians, other vehicles, and your own passengers.

Using your horn continuously might alert others but does not provide you with the necessary visual confirmation that the area is clear. Asking another driver for help can be beneficial, but there’s no guarantee they will be able to assist in ensuring the area is safe. Backing up cautiously without looking can lead to accidents since you might not be aware of obstacles or people behind you. Therefore, checking the area yourself is the most responsible and effective way to ensure safety before maneuvering the bus.
