When you come to an intersection with no stop lines or crosswalks, what should you do?

Answer: C — Yield to any vehicles that have already entered the intersection

If you come to an intersection with no stop lines or crosswalks, you should yield to any other vehicles that have already entered the intersection. Option A and B suggest to proceed when safe, but in this situation, you should give the right of way to any vehicles that have already started crossing the intersection. Option D is incorrect because you must always follow traffic laws and yielding to other vehicles is a part of safe and responsible driving.
