What are the three main categories of signs?

The identification of the three main categories of signs—regulatory, warning, and informational—reflects the essential functions these signs serve in maintaining road safety and facilitating efficient navigation.

Regulatory signs are crucial as they communicate mandatory requirements that drivers must follow to ensure safety and compliance with traffic laws. These include stop signs, yield signs, and speed limit signs, which directly impact driver behavior and roadway safety.

Warning signs alert drivers to potential hazards or changes in road conditions, such as curves, pedestrian crossings, or road work ahead. They are designed to promote caution and help prevent accidents by notifying drivers of what to expect on their journey.

Informational signs provide essential guidance to drivers, offering details about directions, distances, and services available. This category encompasses signs that denote destinations, rest areas, and points of interest, helping drivers navigate more effectively.

These three categories capture the fundamental messages that signs convey on the roadways and are widely recognized in traffic regulations and driver education programs.
