Which are the three types of traffic control signs?

• A. Informational, Construction, and Regulatory Signs
• B. Warning, Informational, and Construction Signs
• C. Guide, Warning, and Regulatory Signs
• D. Regulatory, Warning, and Guide Signs

Answer: (D)

Traffic control signs are grouped by function into three main categories: Regulatory signs enforce laws and require you to take or not take certain actions; Warning signs alert you to hazards or changes in road conditions ahead; Guide signs provide directions, destinations, and other information to help you navigate. This combination—Regulatory, Warning, and Guide signs—covers the legal requirements you must follow, the hazards you need to anticipate, and the navigational information you rely on. Construction signs aren’t a separate primary category; they’re temporary indicators typically treated as part of warning or guide contexts during work zones. Informational signs are usually considered part of the guide/signs category as well. Therefore the three types listed together as Regulatory, Warning, and Guide Signs best describe the standard classification.
