Are stops required at a crossing where a flagman directs traffic to proceed?

In situations where a flagman is present and directing traffic, stops are not required if the flagman is signaling for vehicles to proceed. The flagman serves as an authority figure, actively managing the flow of traffic for safety. If the flagman indicates that it is safe to go, drivers should follow those instructions to ensure smooth and safe passage through the area.

When considering the context of the other options, it's important to highlight that while there are circumstances (such as specific construction zones or emergency situations) that might typically require stops, the presence of a flagman with clear instructions overrides those requirements in this case. This emphasizes the importance of obeying a flagman's signals to ensure safety and compliance with traffic regulations.
