What are temporary traffic signals used for in construction zones?

Temporary traffic signals are utilized in construction zones primarily to manage and control traffic flow when permanent traffic signals are absent or when existing road configurations are altered due to construction activities. These signals help ensure that vehicles are directed safely and efficiently through areas where there may be obstructions or changes in the usual traffic patterns.

By implementing temporary signals, jurisdictions can maintain a level of order and safety on the roads, minimizing the risk of traffic accidents and facilitating the ongoing construction work. This is especially important in situations where construction may restrict lanes or where workers and machinery are present, requiring careful guidance for motorists.

In contrast, while temporary signals may indirectly help reduce congestion and enhance the flow of traffic, that is not their primary purpose. Their main function focuses on controlling traffic in a safe manner during the transitional phase of construction. Additionally, such signals do not provide information about detours or indicate speed limits, as those tasks are typically managed through signage and other traffic management methods.
