If your headlights fail while driving at night, what is the first action you should take?

Answer: B — Try the headlight switch

When your headlights fail while driving at night, the first action you should take is to try the headlight switch. This step is crucial because the issue could be as simple as a malfunction with the switch itself rather than a complete failure of your headlights. By toggling the switch, you may restore functionality to your headlights, allowing you to continue driving safely without further delay. Taking this action before anything else ensures that you are addressing a potentially fixable problem right away. If the headlights come back on, you can avoid additional risks associated with driving in the dark without proper lighting. After attempting to adjust the switch, if your headlights do not respond, then you can consider reducing your speed and pulling over or using your hazard lights to alert other drivers to your situation.
