Answer: D — Slow down and prepare to stop

When entering an intersection with a flashing yellow light, you should slow down and prepare to stop. This is because a flashing yellow light indicates that you should proceed with caution and be prepared to yield to any oncoming traffic or pedestrians. Option A, speeding up, would be dangerous as it puts you and others at risk of a collision. Option B, coming to a full stop and proceeding when safe, is incorrect as you are not required to come to a complete stop at a flashing yellow light. Option C, treating it like a regular yellow light, is also incorrect as a flashing yellow light has a different meaning and requires a different response than a regular yellow light.
