When must you use your headlights while driving?

Using your headlights from half an hour after sunset to half an hour before sunrise is critical for maintaining visibility and safety on the road. During this time, natural light diminishes significantly, making it harder for drivers to see other vehicles, pedestrians, and obstacles. Headlights not only illuminate the road ahead but also make your vehicle more visible to others, reducing the risk of accidents.

It's also important to note that while headlights are crucial at night, their usage impacts safety any time visibility is compromised. Other conditions, such as rain, fog, or snow, may require the use of headlights, but those specific situations are more about weather conditions rather than a strict requirement based on time of day. This distinguishes the requirement from the option that suggests using headlights only during nighttime, which would overlook critical visibility periods.
