When should you turn on your headlights?

  1. 1 hour after sunset

  2. 1 hour before sunrise

  3. 30 minutes after sunrise

  4. 30 minutes before sunset

The correct answer is: 30 minutes before sunset

Headlights should be turned on 30 minutes before sunset, as this is when the natural light is starting to dim and it becomes necessary to use artificial light to help improve visibility while driving. The other options are incorrect because they either mention a specific hour rather than the recommended time frame, or they suggest turning on headlights during times when there is already ample natural light. This can be potentially hazardous, as it may cause glare for other drivers on the road.
