What is the primary purpose of traffic signs?

The primary purpose of traffic signs is to provide information and instructions to drivers. These signs serve essential functions in managing traffic flow, enhancing road safety, and ensuring that drivers are aware of their surroundings. For instance, traffic signs give directions, indicate rules and regulations such as right-of-way, warn of potential hazards, or provide guidance on speed limits and road conditions. By communicating important information clearly and effectively, these signs help drivers make informed decisions on the road, contributing to overall traffic safety.

In contrast, decorating the roads is not a functional purpose of traffic signs; they exist to serve important traffic-related roles rather than for aesthetic purposes. Traffic signs are designed to clarify rules and streamline traffic, not to confuse drivers, which could lead to dangerous situations. While some signs indicate speed limits, their role is much broader; they also encompass a variety of signals that contribute to safe and efficient driving practices.
