What is the function of a bus route map?

A bus route map serves to outline the designated path and stops for the school bus, ensuring that drivers know the specific route they are to follow. This information is crucial for maintaining safety, efficiency, and reliability in transporting students to and from school. By providing a clear visual representation of where the bus needs to go, including pickup and drop-off points, the map helps drivers plan their travel, anticipate traffic conditions, and provide consistent service for students.

While other options focus on different aspects of transportation, their relevance is not as central to the primary function of a bus route map. For example, showing the location of bus depots pertains to operational logistics rather than the actual route taken, and indicating emergency exit routes or displaying speed limits address safety and regulatory aspects but do not convey the needed information about the bus's path and stops.
