When is it permissible to pass another school bus?

When passing a school bus, the most critical factor to consider is the safety of the children boarding or alighting from the bus. The correct answer indicates that it is only permissible to pass a stopped school bus when the bus driver gives a specific signal that indicates it is safe to do so. This could involve a visual cue such as a hand signal or the bus’s signal lights indicating that it is clear to proceed.

This ensures that drivers are aware of the potential hazards of children in the vicinity, who may be crossing the street or near the bus itself. School bus safety laws are designed to protect students, and passing while the bus is still in the process of loading or unloading poses significant risks.

The other choices entail misunderstandings of these safety guidelines. For instance, simply relying on another driver’s signals or the markings of the road do not provide the assurance needed regarding the safety of children. It is essential to adhere to the indications given by the bus driver for the safety of all involved.
