What does a "road work ahead" sign mean?

The "road work ahead" sign indicates that there may be construction or maintenance activities occurring further down the road. This sign is a critical safety measure designed to alert drivers that the road conditions may change due to work zones, which can include lane closures, workers in the area, or changes in the roadway surface. It is important for drivers to be aware of this sign so they can reduce speed, remain vigilant, and be prepared for unexpected situations, such as delays or detours. This awareness not only helps maintain safety for the drivers but also for the workers carrying out the maintenance or construction tasks.
