When must your headlights be on?

Headlights must be turned on when visibility is less than 1,000 feet to ensure safety on the road. This regulation helps drivers to see clearly and be seen by others, particularly in adverse weather conditions such as rain, fog, or snow, where visibility can drop significantly. Using headlights in these situations increases the likelihood that other drivers and pedestrians can see your vehicle, contributing to safer driving conditions.

While it is true that headlights are also necessary at night to illuminate the road and improve visibility, this answer specifically addresses the broader requirement for conditions that affect visibility. Other options suggest circumstances that may not fully encompass the legal requirements for headlight usage, such as relying purely on personal judgment or only using them during specific times of day without regard for visibility conditions.
