Which statement about headlights is correct?

• A. Headlights should be on at all times
• B. You need to use headlights if you can't see a pedestrian 500ft ahead of you
• C. Headlights are not required in daylight
• D. High beams should be used in all conditions

Answer: (B)

Headlights are about visibility and safety in conditions where you can’t rely on your eyes to see far enough. The rule focuses on how far you can see clearly: if you can’t clearly see a pedestrian or other object at about 500 feet, you should have your headlights on. This helps you both see hazards and be seen by others, reducing the chance of a collision.

That’s why the statement about using headlights when you can’t see a pedestrian 500 feet ahead is the best choice. It reflects the practical guideline for when lights are needed to maintain safety in limited visibility.

The other ideas aren’t as reliable: headlights aren’t required to be on at all times in daylight, even if turning them on can help visibility in some conditions; there are times in daylight or in poor weather when you should use headlights, but the blanket claim that they’re not needed in daylight is not accurate. High beams aren’t appropriate in all conditions; they should be used only in very dark situations with no other vehicles nearby, and should be dimmed when another vehicle is present.
