What are the three primary types of road signs?

The three primary types of road signs are regulatory signs, warning signs, and guide signs. Regulatory signs are designed to inform drivers of laws and regulations that must be followed, such as speed limits, stop signs, and yield signs. They typically use a rectangular or circular shape with red, white, or black colors to convey important directives that must be adhered to for safety and compliance with traffic laws.

Warning signs alert drivers to hazards or changes in road conditions ahead, such as curves, pedestrian crossings, or construction zones. These signs generally have a diamond shape and use bright yellow colors to grab attention and convey the need for caution.

Guide signs provide helpful information to drivers, such as directions, distances, points of interest, and services. These signs often use green or blue colors to indicate various routes or facilities, helping ensure that drivers can navigate efficiently.

Understanding these categories helps in recognizing the purpose of each sign while driving, ultimately promoting safer road usage. Other options included different classifications, but did not encompass the three main types recognized in road safety guidelines.
