Using your headlights from half an hour before sunset until half an hour after sunrise and when visibility is reduced is mandated for the safety of all road users. This regulation ensures that drivers can see the road clearly in low-light conditions, such as dusk or dawn, and also enhances the visibility of the vehicle to other drivers and pedestrians.

Visibility is not only affected by the time of day; conditions such as rain, fog, snow, or any circumstance that impairs sight also necessitate the use of headlights. For instance, heavy rain reduces visibility significantly, making it crucial for vehicles to be seen and to see the road clearly, which emphasizes the importance of using headlights in such conditions rather than limiting their use strictly to nighttime.

The other options suggest a more limited use of headlights, either to certain time frames or specific conditions, which does not align with safety practices that aim to minimize accident risk by ensuring consistent visibility in a range of driving situations.
