What is the purpose of traffic signs?

The purpose of traffic signs is to provide essential information to drivers about rules, hazards, and directions. Traffic signs serve as a crucial communication tool on the roadways, helping ensure safety and efficiency in traffic flow. They inform drivers of speed limits, road conditions, regulatory requirements, and directional guidance, thereby assisting in making informed decisions while driving.

For example, regulatory signs indicate what drivers must or must not do, such as stop or yield, while warning signs alert them to potential hazards like curves or pedestrian crossings. Directional signs help drivers navigate roads and find routes, making the journey smoother and safer.

The other choices do not capture the fundamental role traffic signs play in road safety and navigation. Traffic signs are not designed for entertainment, they are not limited to conveying speed limits, and they do not present historical facts about the area, as their primary function is to enhance driving safety and provide pertinent information to users of the road.
