Final answer:
If you have your windshield wipers on, you must also have your headlights on. This is a safety requirement that helps improve visibility and prevents accidents during reduced visibility conditions.
Step-by-step explanation:
When you have your windshield wipers on, you must also have your headlights on. This is because when it is raining or when visibility is reduced, using your headlights can help improve your visibility and make it easier for other drivers to see you.
Having your headlights on in addition to your windshield wipers is a safety requirement in many countries and states. It helps prevent accidents and ensures that you and other drivers on the road can see each other clearly.
While it's important to use your headlights in these conditions, it's also essential to avoid looking directly at very bright lights, as this can damage your vision.
