When is it necessary to use headlights during the day?

Using headlights during the day is necessary when visibility is poor due to weather conditions such as fog, heavy rain, or snowfall. These situations can significantly reduce the ability to see and be seen by other road users, creating a potential hazard. Headlights enhance visibility for both the driver and other vehicles, significantly improving safety on the road.

While there may be other times when turning on headlights is advisable, such as in areas with high levels of traffic or poor lighting, the requirement to ensure visibility in adverse weather conditions is a critical safety measure and aligns with driving regulations. Visibility can diminish unexpectedly, making it important for drivers to use their headlights to stay safe and alert others of their presence.
