When should you use your headlights during the day?

Using your headlights during the day is important for ensuring visibility and safety on the road. The correct choice emphasizes that headlights should be activated when visibility is low. This includes conditions like fog, heavy rain, or snow, where it becomes difficult for other drivers to see your vehicle. By using your headlights in these situations, you enhance your visibility to others, which can significantly reduce the likelihood of accidents.

In contrast, while there are circumstances such as severe weather or driving on highways, these do not cover the broader situations that can lead to low visibility. Furthermore, headlights can be beneficial any time of the day—especially in conditions where the natural light does not provide adequate visibility, which is captured in the other options. However, the main focus should be on using headlights to ensure that you are seen by others when driving in unclear conditions.
