What are two signs that a bus driver should be aware of while driving in a school zone?

Choosing school zone signs and speed limit signs as key indicators for bus drivers is crucial for ensuring the safety of children and pedestrians in those areas. School zone signs provide vital information indicating that drivers are entering a zone with increased pedestrian activity, particularly during school hours when children may be arriving or departing from school. These signs typically mark the beginning of a school zone, alerting drivers to be particularly vigilant.

Speed limit signs are equally important because they set the maximum speed allowed in the school zone, which is typically lower than in other areas to enhance safety. Adhering to these reduced speed limits is essential for giving drivers more time to react to unexpected situations, such as children crossing the street.

While the other choices include various signs that certainly have their own relevance in traffic regulation, they do not specifically address the unique conditions of a school zone, where the safety of children is paramount.
