What do work zone signs indicate?

Work zone signs primarily serve to alert drivers to the presence of construction or maintenance activities nearby. They are crucial for ensuring safety, as they indicate that workers may be present on or near the roadway. This awareness allows drivers to exercise caution, reduce speed, and be prepared to navigate through potential hazards such as heavy equipment, temporary lane shifts, or reduced visibility.

The signs provide essential warnings that are specific to work zones, ensuring that drivers maintain the necessary vigilance in areas where road conditions may change due to ongoing work. This is particularly important to protect not only the workers on the site but also the drivers and passengers who may be traveling through the area.

While other options involve aspects of driving in different scenarios, none specifically capture the primary function of work zone signs as effectively as the indication of warnings about work zones and the presence of personnel.
