What is the primary purpose of construction zone signs?

The primary purpose of construction zone signs is to alert drivers about work areas and ensure safety. These signs are crucial for notifying motorists that roadwork is taking place, which may involve equipment, workers, and changed traffic patterns. By informing drivers of the presence of a construction zone, these signs help reduce the risk of accidents and injuries that can occur if drivers are unaware of potential hazards ahead.

In addition to enhancing safety, construction zone signs often indicate speed limits that are lower than regular limits. This is to ensure that drivers approach the work area with caution, allowing them enough time to react to any unexpected situations. The effective use of these signs plays a significant role in creating a safer environment for both construction workers and road users.

While the other options might touch on ancillary aspects of road usage, they do not address the primary goal of these signs, which is to maintain safety and alertness during construction activities.
