When should headlights be used during the day?

Headlights should be used during the day when visibility is low or in adverse weather conditions, such as rain, snow, fog, or when there are heavy overcast skies. This is crucial for ensuring safety on the road, as using headlights enhances visibility for both the driver and other road users. In adverse conditions, it becomes more difficult for drivers to see and be seen, so turning on headlights can significantly improve overall road safety.

In clear, bright daylight, headlights are typically not necessary unless specified by local laws or specific driving conditions. However, drivers should also be aware of and follow specific regulations regarding their usage. Using headlights during the day in adverse weather conditions not only helps the driver see the road better but also makes the vehicle more visible to others, reducing the chances of accidents.
