What is the primary purpose of traffic signs?

The primary purpose of traffic signs is to regulate, warn, and guide drivers. This is vital for maintaining safety on the roads and ensuring smooth traffic flow. Regulatory signs inform drivers of laws they must obey, such as speed limits or stop signs, which are essential for preventing accidents and ensuring orderly conduct on the road. Warning signs alert drivers to potential hazards or changes in road conditions that may require caution, such as curves or pedestrian crossings. Guide signs provide information regarding directions, distances, and regulations, helping drivers navigate effectively and reach their destinations safely.

In contrast, the other options do not capture the fundamental role that traffic signs play in the transportation system. They are not merely decorative or intended for entertainment, and they do not serve to promote local businesses. Instead, their primary function is rooted in safety and guidance to enhance the overall driving experience.
