Under what circumstance can a flagger station remain unlit at night?

A flagger station can remain unlit at night during emergencies. In emergency situations, the primary concern is often the immediate safety of individuals and the swift response to the crisis at hand, which may override standard procedures for lighting. This allows flaggers to adapt quickly without the necessity of lights, recognizing the urgency of the situation.

Other situations, such as construction projects, routine road maintenance, and traffic signal repair, typically require flagger stations to be well-lit at night to ensure safety for both the flaggers and the passing vehicles. Adequate lighting in these cases helps to clearly communicate instructions, reduces the risk of accidents, and ensures visibility to all drivers.
