Construction zone signs are important safety indicators placed near areas where construction work is taking place. These signs alert drivers and pedestrians to potential hazards, such as road work, detours, or reduced speed limits. They help ensure that everyone remains safe while construction activities are ongoing. Typically, construction zone signs are bright yellow or orange, making them easily visible. Common types of signs include road work ahead, detour, and men at work. By following these signs, drivers can navigate safely through construction areas and minimize the risk of accidents.
