What do regulatory signs communicate to drivers?

Regulatory signs play a crucial role in managing the flow of traffic and ensuring safety on the roads. These signs are designed to communicate essential information about traffic rules that drivers must follow. This includes a variety of directives such as speed limits, stop and yield instructions, and restrictions like no turns or lane usage regulations.

While it is true that speed limits are part of these regulations, the scope of regulatory signs extends far beyond just speed. They provide comprehensive information about all traffic rules, guiding drivers on how to operate safely and legally on roadways. Additionally, some regulatory signs may indicate specific road conditions or necessary actions under certain circumstances, enhancing safety and awareness.

This broad functionality makes it clear that regulatory signs cover much more than just speed limits. Therefore, the correct answer encompasses the full range of information provided by these signs, affirming their essential role in traffic safety and law enforcement.
