Which scenario requires you to turn on your headlights at any time?

Turning on your headlights when visibility is less than 500 feet is essential for safety. This requirement ensures that you can see the road and any potential hazards clearly, while also making your vehicle visible to others. Poor visibility can occur due to various factors, such as heavy rain, snow, fog, or at night. By using your headlights, you enhance your ability to navigate safely and help other drivers notice your presence, which is particularly crucial in low-light conditions.

In contrast, while using headlights in fog or unfavorable weather conditions is important, the law specifically mandates their use when visibility drops below the 500-foot mark. Daytime driving typically does not require headlights unless conditions are severely poor, and while you should be cautious in construction zones, headlights are not universally required unless visibility is compromised. Understanding these specific conditions helps ensure that you follow traffic safety laws effectively.
