Which code would require an immediate response to traffic hazards?

The code that requires an immediate response to traffic hazards is 909-T. This designation indicates a type of traffic emergency that necessitates urgent attention from law enforcement or emergency services. Such incidents may involve accidents, hazardous materials spills, or other unforeseen circumstances that can pose safety risks not only to the involved parties but also to the traveling public in the area.

Immediate response is critical in these scenarios to prevent further accidents, manage traffic flow, and ensure public safety. The use of this code helps streamline communication among emergency responders and facilitates a coordinated approach to handling the situation effectively. In contrast, the other codes do not pertain to traffic hazards requiring immediate attention and may involve less urgent situations or other types of incidents.
