What is the purpose of traffic signs?

The purpose of traffic signs is to provide information and instructions to drivers. These signs play a crucial role in road safety and traffic regulation by conveying vital information about the rules of the road, potential hazards, directions, and regulations regarding speed and vehicle operations. By clearly presenting this information, traffic signs help guide drivers, ensuring smooth traffic flow and reducing the risk of accidents.

While other options may touch on aspects of road management, they do not encompass the broader and essential role that traffic signs serve in informing all road users, which is their primary function.
