What is the main purpose of traffic signs?

The primary purpose of traffic signs is to provide information and instructions to drivers. These signs serve crucial roles in maintaining safety, organization, and flow of traffic on the roads. By conveying important information, such as speed limits, directions, and warnings about potential hazards, traffic signs help drivers make informed decisions as they navigate the roadways.

Without these signs, drivers would struggle to understand the rules of the road or react appropriately in various situations, leading to increased confusion and potentially dangerous driving conditions. The well-designed and strategically placed signs promote consistent communication to all road users, ensuring everyone can understand what is expected of them while driving. This standardization is essential for the smooth functioning of both local and interstate travel.
