What flagging type is characterized by work lasting more than 1 hour at night?

The type of flagging characterized by work lasting more than one hour at night is known as Intermediate-Term Stationary. This classification is significant because it involves managing traffic for extended periods in a specific location, particularly during nighttime when visibility is lower and driver attentiveness may vary.

Intermediate-Term Stationary flagging is used to outline a structured plan for areas where vehicles will experience delays due to ongoing work. The longer duration requires more extensive setup, including signage and potentially more personnel to ensure safety and effective traffic control. This distinction is vital as it informs how to prepare for potential hazards associated with longer nighttime operations and ensures that flaggers can effectively communicate with both drivers and crew members.

Understanding this classification helps flaggers and traffic control professionals set up the appropriate measures to ensure safety and efficiency in managing the traffic flow during extended work periods, especially in low-visibility conditions.
