Final answer:
It is generally true that headlights must be used when windshield wipers are on in poor weather conditions for increased safety and visibility. This is a common road safety law. However, one should avoid looking directly at bright lights to prevent vision impairment.
Step-by-step explanation:
The statement that you must use your headlights whenever you use your windshield wipers as a result of bad weather is generally True. This is a common law in many states, aimed at increasing visibility and safety during inclement weather. When visibility is reduced due to rain, snow, sleet, or fog, using your headlights can help other drivers see your vehicle. The headlights on your car serve a dual purpose; they help you see more clearly and make your vehicle more visible to others.
While there could be some variance in law depending on the state or country, it's a widely accepted practice to use headlights during poor weather conditions where windshield wipers are necessary. It should be noted, however, that drivers should not look directly at very bright lights, including oncoming headlights, as it can be damaging to the eyes and may temporarily impair vision, which can be particularly dangerous while driving.
