What does a flashing yellow light mean?

Answer: B — Proceed with caution

A flashing yellow light indicates that you should proceed with caution. This option is the right answer because a flashing yellow light usually indicates that you should slow down and be prepared to yield to oncoming traffic while continuing through the intersection. Option A is incorrect because a flashing yellow light is not synonymous with a red light, which means "stop." Option C is incorrect because you should not come to a complete stop at a flashing yellow light unless it is necessary to yield to oncoming traffic. Option D is incorrect because yielding the right-of-way is only necessary in certain situations, whereas a flashing yellow light is a general caution to proceed with caution.
