What is the primary function of traffic signs?

The primary function of traffic signs is to regulate, warn, and guide traffic. These signs play a crucial role in maintaining order and safety on the roads. Regulatory signs inform drivers of the laws they must follow, such as speed limits or no parking zones, ensuring that everyone adheres to traffic regulations. Warning signs alert drivers to potential hazards or changes in road conditions, such as construction zones or sharp turns, helping to prevent accidents. Guidance signs provide information to assist drivers in navigating the roadways, indicating directions to destinations or distances to landmarks. Collectively, these functions help ensure the safety and efficiency of vehicular and pedestrian traffic.

While aesthetic appeal may enhance the driving experience, and directions for tourists or advertisements might provide useful information, they do not comprise the primary purpose of traffic signs, which is focused on regulating and facilitating safe movement within transportation systems.
