Final answer:
The statement "Yield also means stop if you cannot merge safely into the flow of traffic" is false. Yielding means slowing down or stopping if necessary, but not always coming to a complete stop.
Step-by-step explanation:
The statement "Yield also means stop if you cannot merge safely into the flow of traffic" is false. When you see a yield sign, it means you must slow down or stop if necessary, but you do not have to completely stop unless it is absolutely necessary to safely merge into traffic. Yielding allows you to give the right of way to other vehicles, but stopping is not always required.
