Which types of signs provide information about traffic laws?

Regulatory signs are critical for communicating traffic laws and regulations that must be followed by drivers. These signs convey important instructions that help maintain order and safety on the road. Examples of regulatory signs include stop signs, yield signs, speed limit signs, and no entry signs. These signs indicate mandatory actions or restrictions that drivers are legally required to adhere to.

While warning signs indicate potential hazards or changes in road conditions, they do not communicate legal obligations. Therefore, the combination of regulatory and warning signs is not the correct focus for information about traffic laws. Informational signs generally provide guidance or assistance but do not impose legal requirements.

In summary, the correct answer highlights that regulatory signs are specifically designed to enforce traffic laws, making them essential for the safe operation of vehicles on public roads.
