Which sign explains a road's specific do's and don'ts?

Regulatory signs are designed to inform drivers of specific laws and regulations that must be followed on the road. They convey essential do's and don'ts that help manage traffic flow and improve safety. For instance, signs indicating speed limits, no entry, stop, and yield are all examples of regulatory signs. These signs help ensure that drivers understand their responsibilities while operating a vehicle and are often accompanied by legal consequences if ignored.

In contrast, warning signs are intended to caution drivers about potential hazards or changes in road conditions ahead, such as sharp curves or pedestrian crossings. Guide signs provide information about directions, distances, and points of interest, helping with navigation rather than enforcing rules. Informational signs typically offer non-regulatory information about services, facilities, or nearby areas, which do not influence how a driver must behave on the road.
