What type of sign indicates an upcoming side road?

• A. Warning Sign
• B. Guide Sign
• C. Regulatory Sign
• D. Information Sign

Answer: (D)

An upcoming side road is a change in the driving environment that you need to prepare for, such as potential entering traffic from the side. Signs like this are placed as warnings to alert you to a condition ahead so you can adjust your speed and be ready to react. That reasoning is exactly what a warning sign is for: it signals hazards or changes in road geometry ahead. Guide signs provide directions to destinations, regulatory signs tell you what you must or must not do, and information signs give general information about services or locations. So the sign indicating an upcoming side road is a warning sign.
