In what situation should you use your headlights during the day?

Answer: B — When visibility is limited due to weather conditions

Using headlights during the day is particularly important when visibility is limited due to weather conditions, such as rain, fog, snow, or overcast skies. In these situations, headlights enhance your ability to see the road and allow other drivers to see your vehicle more clearly. This practice not only improves safety by reducing the likelihood of accidents but also helps you remain visible in conditions where natural light may not be sufficient for safe driving. While there may be other moments when headlights are beneficial, such as in residential areas or during heavy traffic, it's specifically the reduced visibility scenarios prompted by adverse weather that necessitate using headlights to ensure maximum visibility and safety on the road.
