What does a solid yellow arrow signal indicate?
Answer: B — Proceed with caution, yielding to oncoming traffic.
A solid yellow arrow signal indicates that you should proceed with caution and yield to oncoming traffic. Options A, C, and D are incorrect because they all indicate making a turn, while a solid yellow arrow specifically means to yield to oncoming traffic. Option A is incorrect because it does not mention yielding. Options C and D are incorrect because they mention making a turn without acknowledging the need to yield to oncoming traffic first. Therefore, the correct answer is B.
