What action should a Traffic Signal Technician take in the event of a power outage?

In the event of a power outage, activating backup systems and notifying management for repair is the most appropriate course of action for a Traffic Signal Technician. This response is critical because it ensures that traffic flow can be maintained using alternative power sources, such as battery backups or generators, which may keep the signals operational despite the outage.

Furthermore, notifying management is vital for addressing the underlying issues causing the outage and coordinating repairs swiftly. This action not only helps manage traffic safety but also facilitates a quicker restoration of normal operations. By focusing on backup systems and communication, a technician minimizes the potential for accidents and ensures that traffic control measures remain in place as effectively as possible until power is restored.
