What is the primary function of traffic signs?

The primary function of traffic signs is to provide important driving information and instructions. Traffic signs are essential for safe and efficient road use as they communicate various rules and regulations that drivers must follow. This includes information about speed limits, warnings for hazards, directions, and guidance on navigating intersections and road conditions.

These signs are strategically placed to be easily visible, ensuring that drivers can make informed decisions while on the road. Their standardization across regions also helps maintain consistency, making it easier for drivers to understand and react appropriately regardless of where they are driving.

The other options do not accurately capture the main purpose of traffic signs. Traffic signs are not designed to confuse drivers; rather, they aim to clarify and simplify navigation. While aesthetics can play a minor role in some urban areas, it is not the primary goal of traffic signage. Lastly, limiting the speed of vehicles is just one of many functions that traffic signs serve, not the overall primary function.
