Under what conditions should headlights be used?

Headlights should be used half an hour after sunset until half an hour before sunrise because visibility is significantly reduced during these times. Using headlights during these hours ensures that you can see the road clearly and be seen by other drivers, which is crucial for safety. This requirement aligns with safe driving practices that promote better visibility for both the driver and other road users, reducing the risk of accidents that can occur in low-light conditions.

While headlights are also beneficial in foggy conditions and during rainy weather, those specific scenarios do not encompass all scenarios where headlights should be operational, making the requirement of using headlights from sunset to sunrise a crucial guideline for driving safety at all times during low visibility.
