What is the purpose of traffic signs?

Traffic signs serve the critical functions of regulating behavior on the road, warning drivers of potential hazards, and guiding them safely to their destinations. The regulation aspect involves enforcing traffic laws and controlling the flow of vehicles to ensure safety and efficiency. Warning signs are vital for alerting drivers to dangerous conditions or unexpected situations, such as sharp turns or pedestrian crossings, helping to mitigate accidents. Guidance signs assist with navigation, providing information about directions, distances, and local points of interest, enabling drivers to make informed choices while driving.

The other options do not encompass the full scope of what traffic signs are meant to achieve. While some signs may serve decorative purposes or indicate construction zones, those are not their primary functions. Traffic signage is primarily about promoting safety, effective communication to drivers, and maintaining order on the roads.
