Which of the following is not an example of a road construction sign?

The choice "No Way" is not an example of a road construction sign because it does not relate to construction or maintenance work typically found on roadways. Road construction signs are specifically designed to inform drivers of changes in traffic patterns, hazards due to roadwork, or instructions related to construction and maintenance activities.

In contrast, signs like "Detour Ahead," "Shoulder Work," and "Flagger Ahead" all serve the purpose of alerting drivers to ongoing construction efforts, indicating temporary road conditions, or guiding them through altered routes. Each of these signs plays a critical role in ensuring safety and facilitating smooth travel through construction zones.
