What does the sign indicate about drivers on the roadway?

Answer: A — Watch for people working on or near the roadway

This answer is correct because the sign indicates that drivers should be alert for individuals who are working on or near the roadway. Such signs are typically used to ensure the safety of both workers and drivers, making it crucial for drivers to slow down, exercise caution, and be prepared for any changes in traffic patterns that may occur due to construction or maintenance activities. While the other choices refer to different scenarios—such as a warning that the road ends or a signal that a traffic signal is ahead—none address the presence of workers on the road. Understanding and recognizing these signs is vital for maintaining safety on the roads.
