When should traffic control devices be removed from a work zone?

Traffic control devices should be removed from a work zone after all work is completed and it is safe for normal traffic flow to resume. This is essential for ensuring the safety of both the workers and the motorists. Leaving traffic control devices in place after work is finished can cause confusion or unsafe conditions for drivers who may not expect to see unmanned controls. Furthermore, removing devices too early could put ongoing safety measures at risk, especially if there are still tasks or inspections to be completed. By following this protocol, traffic flow can be restored efficiently without compromising roadway safety.
