Which of the following is NOT a characteristic of a construction zone?

In the context of construction zones, the primary characteristics include specific signage, barriers, and the presence of workers to indicate ongoing work and ensure safety. Bright orange cones and barriers are commonly used to mark the construction area and guide vehicles, while signage indicating detours is essential to inform drivers of changes to the usual route due to the construction.

Workers present during daylight hours is another characteristic, as it highlights the active nature of the work zone and serves as a reminder for drivers to remain cautious.

The use of green directional signs, however, is not typical in construction zones. Green directional signs are generally used for providing information about highways, routes, and destinations, indicating normal traffic patterns rather than temporary conditions or hazards like those found in construction areas. Therefore, identifying a green directional sign as not belonging to the characteristics of a construction zone is accurate, as it does not serve the purpose of either indicating detours or the presence of hazards and personnel in such environments.
