When should headlights be used during the day?

Using headlights whenever visibility is reduced is essential for safety while driving. This includes conditions such as rain, fog, dusk, dawn, or any other situation where visibility is compromised. The primary function of headlights is to illuminate the road ahead and make the vehicle more visible to other drivers. By using headlights in reduced visibility conditions, drivers enhance their own ability to see road signs, hazards, pedestrians, and other vehicles, while also ensuring that they are seen by others. This practice contributes to overall road safety and helps prevent accidents.

In contrast, headlights are not specifically limited to residential areas, nor are they unnecessary during the day. Additionally, the time of day or whether a driver is alone does not dictate the need for headlights; what matters is the visibility conditions at the time of driving.
