If during a repair, flashing operation isn't available, what step should be taken?

When flashing operation is not available during a repair, notifying law enforcement to control traffic is the most appropriate step to take. This action ensures that trained personnel can manage traffic safely, reducing the risk of accidents and ensuring a clear path for both motorists and workers on site. Law enforcement officers are equipped to create a safe work zone, directing vehicles and pedestrians around the repair site, which enhances safety for everyone involved.

Waiting for the flashing operation to resume is impractical in a situation where immediate repairs need to occur, as this could delay the restoration of safe traffic conditions. Proceeding with repairs without notification could pose serious hazards, as motorists may not be prepared for unexpected changes in traffic patterns. Requesting emergency personnel could also be beneficial in specific scenarios, but law enforcement is generally the first line of defense in managing traffic during such repairs. Thus, notifying law enforcement is the critical step in maintaining safety while optimal repair work is being conducted.
