When should you turn on your headlights?

• A. 30 minutes before sunrise/sunset
• B. When it is completely dark
• C. Only during the day
• D. When you pass a vehicle

Answer: (A)

Headlights should be on during low-light periods so you’re visible to others and can see the road clearly. Turning them on about 30 minutes before sunrise or sunset covers the twilight moments when darkness is starting to set in or fading, giving you better visibility and making you more noticeable to other drivers as lighting conditions change.

Waiting until it’s completely dark misses the time when you still need extra visibility, and using headlights only during the day or only when you pass another vehicle doesn’t address the period when hazards appear early or fade late. Twilight is exactly when lights help the most, so turning them on in advance of full darkness is the safer choice.
