Final answer:
The red and white triangle yield sign is a regulatory sign used to instruct drivers to slow down and give way. Option D is correct.
Step-by-step explanation:
The red and white triangle yield sign you are asking about is a regulatory sign. Unlike warning signs which are typically diamond-shaped and meant to alert drivers of potential hazards, or guide signs which provide directions, a yield sign is used to instruct drivers that they must slow down and give way to any vehicles or pedestrians in the path they are about to enter.
Similarly, construction signs have a distinct orange color and are used mostly in construction zones. Therefore, the correct answer to your question is D. Regulatory Sign.
The sign described (red and white, triangle yield sign) is a regulatory sign.
Regulatory signs are placed by the government to inform drivers of laws and regulations they must follow.
Yield signs, like the one described, are regulatory signs that indicate drivers must give the right-of-way to other traffic at an intersection or merge point.
Therefore, the correct answer is D.
