What are the three classes of traffic signs?

The classification of traffic signs into regulatory, warning, and guide is fundamental in traffic management and safety.

Regulatory signs are designed to inform drivers of specific laws or regulations that must be followed. Examples include stop signs and speed limit signs, which dictate the behavior of drivers in order to maintain safe road conditions.

Warning signs are used to alert drivers to potential hazards or changes in the road conditions ahead. These signs typically indicate situations such as curves, intersections, and changes in driving surfaces, allowing drivers to adjust their behavior accordingly to ensure safety.

Guide signs provide information that assists drivers in navigation. These include directional signs, mileage markers, and signs that locate services. They are essential for helping drivers understand their route and make informed decisions about directions and stops.

The other options present classifications that are either too narrowed down or are not commonly used terms in traffic sign classification. For instance, using specific signs like stop, yield, and caution does not encompass the full range of regulatory, warning, and guide signs. Similarly, terms like mandatory and advisory, or direction and instruction do not accurately reflect the standard traffic sign categories used in traffic control planning and implementation. By understanding the primary classes of traffic signs, individuals involved in traffic control can effectively manage and enhance roadway safety
