What type of signs warn about upcoming road maintenance or construction?

Road Works Ahead Signs are specifically designed to alert drivers about upcoming road maintenance or construction activities. These signs are crucial for ensuring safety and preparing drivers for potential changes in road conditions, such as detours, lane closures, or reduced speed limits. By providing timely warnings, these signs help to prevent accidents and improve overall traffic flow during maintenance operations.

Other types of signs, while related to road conditions, do not serve the same purpose. Road Obstacle Signs indicate specific hazards on the road, Road Width Signs inform drivers of the width restrictions ahead, and Informative Signs provide general information but may not specifically address maintenance or construction activities. Understanding the function of each type of sign is essential for navigating the roads safely and effectively.
