In some regions, flags are restricted to emergency signaling only. Is this statement true or false?

The statement is true. In certain regions, the use of flags for traffic control may indeed be restricted solely to emergency signaling situations. This regulation is typically rooted in safety standards designed to minimize confusion among drivers and ensure that traffic control methods are clear and standardized. Flags can be ambiguous and may not effectively convey specific traffic control instructions when used outside of emergencies.

Because of this, most jurisdictions prefer established traffic control devices, such as signs and cones, for everyday traffic management in work zones. The use of flags might only be permitted in special circumstances to indicate an urgent situation, thereby allowing trained personnel to react appropriately to threats in the area. Recognizing these regional regulations emphasizes the importance of adhering to local traffic control guidelines, which are designed to maintain safety for both workers and drivers.
