What is the main purpose of warning signs?

The primary function of warning signs is to indicate danger. These signs serve as visual cues that alert individuals to potential hazards in their environment, whether it involves construction sites, roadways, or any area where safety risks exist. By clearly conveying warnings about possible dangers, these signs aim to prevent accidents and injuries by making individuals aware of the risks they may encounter.

In contrast, directing traffic pertains to signs that guide vehicular movement, ensuring orderly traffic flow. Providing instructions usually involves more detailed information on how to perform a certain task or follow a specific procedure rather than merely alerting to danger. Facilitating movement is related to helping people navigate spaces efficiently, which is distinct from the primary goal of warning signs to heighten safety awareness about risks.
