What is the primary purpose of traffic signs?

The primary purpose of traffic signs is to offer information and instructions to drivers. They play a crucial role in maintaining traffic flow and ensuring the safety of all road users. Traffic signs convey important messages about speed limits, road conditions, directions, and regulations that drivers must follow. This information helps drivers make informed decisions, navigate safely, and understand the rules of the road, thereby reducing the likelihood of accidents and improving overall traffic efficiency.

While other choices may seem relevant, they do not encapsulate the comprehensive purpose of traffic signs. For example, traffic signs do not serve as entertainment; their seriousness impacts road safety. They also do not specifically target traffic police, as they are designed for the general public. Additionally, warning signs about road construction are just one category of the types of information traffic signs provide, but they do not represent the overall purpose of all traffic signs. Hence, the focus on providing clear, critical information and instructions to drivers solidifies why this answer is the best choice.
