To help others see you when daylight begins to fade, you should use your:

  1. Parking lights.
  2. Low beam headlights. ✓
  3. Emergency flashers.

Answer: B. Low beam headlights.

Use your low beam headlights to help others see you as daylight begins to fade.

Why this is the answer

The handbook says headlights make it easier for other drivers to see your vehicle, and it lists using them when the sun is low on the horizon. It also says it is illegal to drive with only parking lights. Among the choices, low beam headlights are the headlight setting for making your car visible in fading daylight; emergency flashers are described for pulling off the road when conditions are too bad to continue.

Why the other answers are wrong

Remember it

When the sun sits low, switch on low beams so other drivers can spot your car.
