What is the main purpose of traffic signs?

The main purpose of traffic signs is to give information and directions to drivers. These signs are essential for maintaining road safety and ensuring efficient traffic flow. They communicate important information regarding speed limits, upcoming intersections, warnings about hazardous conditions, and guidance on the routes drivers should take. By providing clear and standardized messages, traffic signs help drivers make informed decisions on the road, ultimately reducing the likelihood of accidents and improving overall traffic efficiency.

The other options do not accurately reflect the primary function of traffic signs. While the idea of marketing for businesses or entertaining drivers may seem appealing, they do not align with the fundamental safety and informational roles that traffic signs serve. Creating obstacles on the road contradicts the very purpose of traffic signs, which is to aid and guide drivers, not hinder their ability to navigate safely.
