When should headlights be used?

Headlights play a crucial role in ensuring visibility and safety while driving. They should be used in foggy or rainy conditions, or at night because these situations significantly reduce visibility. During fog or heavy rain, the light from the headlights can help illuminate the road and other vehicles, but it’s recommended to use low beams in such conditions to prevent glare that can impair the vision of both the driver and others on the road. At night, headlights are essential for navigating safely, as they allow drivers to see potential hazards and for others to see the vehicle, reducing the risk of collisions.

The other choices do not cover the full scope of when headlights are necessary. Using headlights only during the day overlooks safety needs during adverse weather or nighttime driving. Similarly, restricting the use of headlights to city driving or highway driving fails to address the necessity of proper visibility in various environments and conditions.
