Which of the following is NOT considered a temporary traffic control device?

The reason the traffic light is not considered a temporary traffic control device is that traffic lights are typically permanent installations designed to manage the flow of traffic at intersections or specific locations. They provide ongoing control over vehicular and pedestrian movement, ensuring safety and efficiency in traffic management.

In contrast, cones, barriers, and warning signs are designed for temporary use, often deployed during construction, roadwork, or any situation requiring a short-term adjustment in traffic patterns. These devices are intended to alert drivers and direct traffic safely around hazards or through altered routes, and they can be easily set up and removed as needed, distinguishing them from a traffic light's fixed and long-term nature in traffic management.
