What is the primary purpose of traffic signs?

The primary purpose of traffic signs is to inform drivers of rules, hazards, and directions. These signs play a crucial role in ensuring safe and efficient traffic flow by conveying important information. For instance, regulatory signs indicate traffic laws that must be followed, warning signs alert drivers to potential hazards or changes in road conditions, and guide signs provide directions to help drivers navigate to their destinations.

The function of informing drivers helps prevent accidents by alerting them to necessary actions, such as stopping at a red light or yielding for pedestrians. Moreover, clear signage supports adherence to traffic regulations, thereby enhancing overall road safety. While other options might touch on aspects of traffic signs, they do not capture the essential, functional role that these signs play in facilitating communication between the road and its users.
