When should you use your low-beam headlights?

  1. When it is clear and sunny

  2. When you are following another vehicle

  3. When it is raining or foggy

  4. When you need to signal to other drivers

The correct answer is: When you are following another vehicle

You should use your low-beam headlights when you are following another vehicle. This is because using your high-beam headlights can reflect off the reflective surface of the car in front of you, impairing the driver's vision and causing potential danger. Options A, C, and D are incorrect because clear and sunny weather, rain, and signaling to other drivers do not directly impact your visibility while following another vehicle.
