When must you have your headlights on during the day?

Headlights are essential for visibility and safety, particularly in low visibility conditions like rain or fog. When driving in such situations, having your headlights on enhances your visibility to other drivers and allows you to see the road more clearly. This practice is crucial because it helps prevent accidents caused by reduced visibility, ensuring that you are more easily seen by others. While headlights are also required at dusk and dawn for similar safety reasons, the specific emphasis on low visibility conditions highlights their importance at any time of day when weather conditions impair sight.
