What action do manually operated temporary traffic signs indicate?

Manually operated temporary traffic signs are typically used to control the flow of traffic during situations that require immediate attention, such as road construction, accidents, or other disruptions. These signs serve as a means to provide critical information to drivers, helping them navigate through altered traffic patterns safely.

In particular, when manually operated temporary traffic signs indicate "stop and go" traffic control, they are actively directing vehicles to stop at certain intervals and allow others to proceed. This is essential in maintaining safety and order in high-traffic areas or during events that might otherwise cause confusion. The manual operation of these signs also allows for adjustment based on real-time conditions, making them an effective tool for managing traffic flow.

Other types of signs, such as those for construction activity or emergency vehicle access, may also use manual controls, but they serve different purposes, focusing on informing drivers about specific hazards or access routes rather than controlling traffic flow directly. Speed limit enforcement typically involves permanent signage or digital displays without the need for manual operation. Therefore, the primary function of these manually operated signs is to manage the stop and go traffic effectively, ensuring safe navigation through potentially hazardous situations.
